low FPS @ 1500+ Guests, Good PC, Need Help
Hello coaster enthusiasts, first off id like to say that i do love this game and that i am not a stickler for graphics; i do not need everything on the ultra setting. However that being said, i have everything turned to OFF and graphics at the lowest it can go outside of Texture Quality set to high.

I have struggled since day 1 with this game to achieve stable FPS above 30-60 when i hit 1500 guests. I am aware this game is CPU intensive, but i have a good PC to my best knowledge and i have read post after post across multiple pages of people who are having low FPS on good rigs and players who are achieving SUSTAINABLE good FPS of 25+ AT 5000+ Guests. So what is going on here? Why am i dropping to 20 FPS at 1500?

Before i go any further on my tangent, i will post my specs.

NVIDIA Geforce RTX 3060
Drivers are up to date
Intel Core i7-8700K @ 3.70GHz
1920 x 1080 Res, 120Hz
Two 8xGB RAM, going to purchase more over the weekend

I apologize for the long winded post but for the tech wizards out there, here is what i have done:
1- I have unplugged the graphics card and placed it in the other slots available; no improvement.
2- I have adjusted all settings multiple times, restarted the game doing so just for extra caution; no improvement.
3- I have used NVIDIA Geforce Experience to update drivers and optimize settings; no improvement.
4- I have played on career across multiple maps and the same issue arises; @ 1500 guests my frames plummet to 20-30FPS.
5- i have gone into the NVIDIA control panel and adjusted the preference from Performance to Quality, and Quality to Performance; no improvement
6- I have deleted as many objects and scenery as i can to reduce the strain to load everything
7- I use the ingame steam option to monitor my FPS in the upper left corner, so i can get an understanding of whats going on.
8- I have tried using an older GPU, my 1070 GTX to see if there is any change; no improvement OR change. BOTH seem to run the same regardless of an upgrade to 3060 [which leads me to believe something is wrong with my PC elsewhere]

Now before anyone says "But 20-30 FPS is great, i get sub 10!" Yes, i understand some players would love to be getting 20-30 FPS, i have read pretty much every single post on these discussions about the FPS issue, but my concern and question is why im dipping into those numbers on my PC at ONLY 1000-1500 guests. I really begin to feel it at 1000. And at 700+ the FPS monitor already is going from 60 to 40 and lower, with all settings at lowest and all optional settings turned OFF. [Texture Quality @ high]

Even when i zoom all the way out, which i know is not doing much because the game is calculating all those guests AI and pathing and whatnot, but even then i get the same 20-30 frames. If i even click on any of the tabs [coaster, scenery, building ect.] my frames drop to 5 for a few seconds as it load all those options. [which i guess is to be expected?]

Id like to have a serious discussion on this with players of the game who may have an understanding of whats going on; lets leave rudeness out of this. If anyone can help id greatly appreciate it; ultimately i just want to understand why my FPS is dropping so fast around 1000-1500 every time on any map with the bare minimum settings + bare minimum scenery while OTHER players [barring their own PCs being better/worse then mine] are getting similar or the same FPS of 20-30 at 5000+ , ive read many reports of players getting a good 25-30FPS at those guest numbers, while im sitting here dropping to 20 at lower guests.

Any thoughts on whats going on?

Other people will advise you better than me that's for sure but, the extra RAM that you intend to buy most likely won't make a lot of difference. Maybe a little. Some of the problem with the game is CPU bottle necks.

There is also a lot on Youtube and other articles at the moment about some kind of conspiracy with RTX cards and drivers apparently beginning to ruin gaming. I haven't looked much into it but might be worth a look to find out if anybody is suggesting fixes.

Thank you for the comment. I will do some more searching then on that subject you've mentioned. Its such a shame, i absolutely love this game and ive tried everything in the book that i can think of. The only thing i have NOT done is swap my power settings to High Performance because i dont want to push my computer any further if it is the CPU that is being strained by Planco. The CPU gets to about 70% usage at 1500 guests.

I have read many other discussions of people having better components for their PC struggling with the game, and then people with less powerful gear playing at buttery smooth 60FPS on ultra. It just...makes no sense to me. I dont know whether its just poor optimization , which people have also said, or if its my set up of my computer itself that is the issue.

I would just like to play the game , even if at low-med settings [the game is beautiful still at medium], without my FPS taking a nose dive at ONLY 1000 guests into the game. :(

Regardless, i'd like to keep this discussion open for the time being in case anyone else can come up with a general idea, or even a guess, as to what is going on with my PC/game.

All good points bro. I am quite lucky with it all probably as I like to build the coasters and buildings and try to get them as good as I can but never really go for the full parks and thousands of guests. Maybe will try it one day and compare notes with everybody.
Spooxa Jan 20, 2023 @ 4:15pm 
Im with you on that. I dont plan on ever going past 2000 guests once i finish the career mode and start custom maps or challenges. I dont need thousands upon thousands; i feel comfortable sitting at 800-1200 guests and just watching them do their thing.

My gripe is that i am told i have fairly good components for my PC to run this game, yet it struggles even at low settings with only 1000 guests.[Going from 60FPS at 400 guests to 30 FPS at 900-1000, then droping to 20 FPS at 1500+]

There is an issue somewhere here, but is it the CPU? The Game? Other hardware? No idea. Thank you for your advice, im doing as much searching for answers as i can.
MrHappy Jan 20, 2023 @ 4:35pm 
It definitely is a long standing complaint. As you have noticed, even on the best PC's. It's the game. I bought Red Dead Redemption 2 today as it was on sale and even on my lowly GTX980ti card it runs like a dream in Ultra Graphics even though the entire thing is full on cinematics in gameplay.

But, despite a couple of little flaws in Planet Coaster, many of which are fixed and vastly improved upon in Planet Zoo. You have bought a good game which is a lot of fun.

Whatever happens don't blame your computer :) It's not that. In all honesty I can probably get the same Planet Coaster performance as you.

And yup I am not even sure at this point if it's worth updating my video card. People seem to be having lots of errors and crashes in various games with the newer cards. I am kinda happy that everything works even though this particular game seems to struggle no matter the hardware.

I did see somewhere else with an RTX complaint that just ensuring it is pushed in all the way makes a difference, even a slight offset in the way it is seated in the slot seems to be making a lot of difference for people. That was on the Red Dead forum when I checked earlier.

i heard someone here on the Planco discussions mention pushing in their graphics card just a smidge and it gave them silky smooth frames. I did try that, hoping it would work. Sadly, no deal. I have 3 slots to put my GPU into, and its currently on the top most slot. The 2nd slot is close to the power supply and offers very little air flow; though i did try it in the 2nd slot; no change. The third is just directly sitting above the power supply and there is no way i can put the card in there physically. Bad layout i know

I do still have my GTX 1070 in safe storage, so if anything happens to the 3060 such as crashes or hardware failures i will just go back to the previous.

Its so strange because the performance of the GTX 1070 was and is identical to the 3060 im using right now in terms of FPS. I know the game is heavy strain on CPU though, im aware of that, id just like to find an answer as to what i can do within my power and limits to fix these issues. And thanks for keeping a conversation going with me on this, i hope you're enjoying Red Dead 2 :) !
MrHappy Jan 20, 2023 @ 8:43pm 
Action shooters are not usually my style but yeaaah :) Instantly impressed by Red Dead. Thanks.

Perhaps take a look on the Frontier Forums for additional Planet Coaster recommends as well? Been a while since I have been on there properly but you might find a gold nugget of advice I guess.

Conversation. Well, lots of toxicity in gaming and for a moment I found myself sliding into it. Or dragged into it maybe. People are sometimes doing themselves more damage than they might realise.

Hey, first my Specs:
RTX 3080
Ryzen 9 5900X 12 Core CPU
32GB 3600 MT/s RAM

I have similar issues but with higher amount of guests. I looked into so many threads and everyone is talking about CPU bottlenecks. My Park is not that big. Maybe it uses 20% of the map but with 6000 guests. Some people talking about 60+ FPS with 6k guests and their system is like an Intel i7-3820 and GTX 970. I get around 25 FPS while playing with lowest speed and 40 Fps if the game is paused. With hyperthreading disabled (SMT on AMD) I get 5 more fps. Either way, my CPU is not fully utilized by the game. Always between 60% and 70%. GPU is chilling at 35% and RAM just 4GB of usage. Some people talking about too many effects/rides/coaster/animatronics can cause fps drops too, animatronics especially when they perform at the same time. There was a video on youtube where some guy tested stuff like rides and when he removed coasters support for tracks, especially for wooden coasters his FPS goes up from 50 to 80. I can not confirm anything of this. Read more down below about my short tests.

The other thing is Dirext X 11 is limited. It can only utilize 1 CPU core for DirectDraw calls. Read more here: https://steamcommunity.com/app/493340/discussions/0/1693797713964863251/

I've read many threads where people with many years old CPUs have the same problem around 1000-2000 guests and I think there are some people who are maybe not telling the truth about their FPS. If they are telling the truth, what is the trick? 6k-7k guests with an CPI i7-3820 sems not real. They append Screenshots of their parks but no FPS Counter everywhere, hard to believe. And we all know the internet. You can say almost everything and there will always be someone who will believe you.

Anyway, I started some testing. Deleted everything in my Park. I got 10 more Fps, now at 40 Fps with 6k visitors. After some time the number of guests dropped to 4k and I'm back at 80 Fps. Dropped more to 2k and FPS went up to 120. Then started over again and deleted some rides with more scenery and animatronics, nothing happened. Started over again, let out guests down to 4k THEN the same rides as in the previous attempt and gained FPS from 35 to 60. Wtf? I did some more tests but was not able to figure out a way to have more than 5k visitors without dropping below 30 FPS while the game is running on slowest speed.

The only thing we can do is Upgrade our CPU's and hope the new CPU is able to run that one Dirext X 11 thread which is responsible for DrawCalls faster. Development for PlanCo stopped years ago. They won't port the game over to DirectX 12 because that's not that easy (and not cheap). We can only hope PlanCo 2 gets announced some day and will use DX 12 or newer or some other good new technology.

If you want you can share your park via Workshop and I can see how it runs on my machine.

thank you for the response and for the thorough testing, Torpedo. I have not started a custom or challenge park yet so i have been doing the career mode to get those out of the way. Given, i am aware those maps are prebuilt by the developers and have tons of scenery going on; in the Downtown career map i selected 1 prebuilt building and it had nearly 2000 decorations alone!

That being said though, even on the emptier, smaller maps of the Career mode, even in an almost empty park with only 2 rides and maybe 500 guests, my frames are already notably comparable in dropping when it goes from 500 guests with 90 FPS, down to 40 FPS at 900 guests , with only 4 rides.

Interestingly enough, my PC setup which is less powerful then yours but still good im told, gets those same numbers when monitored. CPU being used at 60-65%, sometimes spiking to 70%, GPU sitting at 35% with the built in fans not even spinning or being on, and 4GB of ram being used. The CPU is definitely being eaten as we know Planco does this with all the unique guest AI, however im getting these numbers at a lower end PC setup. So perhaps it really is just a matter of hardware upgrades sadly.
Though that begs the question whether people are lying about getting buttery smooth 60FPS on their lower end hardware. I shouldnt believe everything im told or read on the internet, though i find it telling when multiple sources say the same thing : "I am getting better performance on a lower end hardware setup compared to higher end". But then there are players who have your experience; having a great PC and running it completely fine at 6k guests. What is going on???? This is so boggling.

Im just curious as to why my FPS is dipping so low at lower guests; while you are able to run it with 6000 guests comfortably? Is it really that i just need to get a new CPU to handle the bottleneck?

Like you, i have spent countless searches looking all over forums, reddit, steam, youtube ect. trying to figure out this problem. It eludes me. What is going on in my PC specifically that is causing this dip so early into the game? With all graphics set to LOW; all options turned OFF ? Not all computers are created equal, but my set up is not horrible, yet my PC is struggling with this game. Its a downer, i dont expect to play at ultra, but id like stability in my frames, even at low graphic settings, and not have to worry about watching the guest numbers climb and going "Oh boy, cant wait to see my FPS drop to 15-20 at 1600 guests!" :(

I know how you feel. It's super frustrating to see FPS drop and you can't do anything about it except stop expanding the park. I did some tests in career mode and I can see the same behavior with dropping frames the more guests in the park.
Results of first Sci-Fi scenario:
Fresh start: 233 guests, 175 FPS (175 Hz monitor), GPU 100%, CPU 30-40%
At the end (all challenges done): 1,5k guests, 115-120 FPS, GPU 70%, CPU: 40-50%
Temperatures both fine. GPU not above 50°C and CPU not above 65°C in both cases.

As you can tell, there is a turning point within the GPU usage. At some specific number of guests GPU load drops to 70%. And I bet with more guests in the career mode test park the load would drop even more while the CPU load would still increase. The GPU starts to calm down because the "cpu bottleneck" everyone talks about isn't a CPU problem but more a software problem with DirectX. The thread responsible for DirectX’s DrawCalls slows the game down, because the game depends on the calculation and waits for it, therefore the GPU won't have to render as much as it can, resulting in less load. Calculating thousands of guests regularly to check if there are new shops, new rides, walkways, etc. is not that cheap for a single thread.

Another thing I forgot to mention for my 6k guests park: Changing graphic settings from ultra to low just raised the FPS about 2-3 FPS, so not worth it.

I hope so much that Frontier will look into this problem some day. I’m not a gamedev but a dev, so I can barely imagine how hard this will be. But sometimes you just need the correct idea to make it work and get around the problem. Just around 2k people are playing this game simultaneously, which is not much, but it’s not dead. 2k people who absolutely love this game.

Well i am grateful for the help and knowledge you've provided. Thank you for that. It is saddening however being unable to diagnose the problem, as complex as it is. On some rigs it seems fine for people, for others, its just a mess.

I too hope Frontier comes back even if only for a moment to help either shed some light on this issue [if they know what the problem is] or make a patch. Understandably it is likely a complex issue with many moving parts, so i wont hold my breath. Though if a miracle arises, hopefully a dev at Frontier sees these posts , albeit the chance is unlikely.

2k people may not seem like alot but just taking a look at the workshop and all the dedicated youtubers and streamers who still love this game; its a passion. This game is a love letter to the older RCT games alot of us grew up on and still love to this day. I hope Frontier sees and knows theres still a dedicated player base and doesnt forget us; i understand they've moved onto their other games and want to move onto other projects but there is still alot of love for Planco, even despite its flaws.

On a positive note, i want to say; despite my dismay at the low FPS issue and the complexity of looking for a solution, i love this game. Hell, i'll likely spend months playing it even though the FPS issue torments me. And hopefully a solution is found by the community if not by Frontier themselves. If i get any change to the situation i'll post whatever i know. Thank you everyone :)

it's an 8700k. Might wanna upgrade that, you are several generations behind and the 8700k loses even to ryzen 2000 cpus
