FPS problem
Hey pro's:) just a quick question..
I had i5 processor 7gn with 16gb of ram and GTX 960 4g graphic card.
Now iv got AMD 3700X with 32gb and Nvidia 1660TI 6gb both with the same ssd and with both of them i got almost the same FPS with the same city i loaded (between 13-16fps)... How could it be?!
Is it true that no matter how good you computer is, its never be smooth enough? 😔

I unsubscribe mods that effect fps but still...13 fps is damn poor

Yes

The same Unity game engine and the same amount of computations and graphical detail.
You cannot do anything about the game engine, but you can do something about the rest...

This is the problem ... badly coded resource management ... on top of that , they never optimizedf anything .... just more DLC ...

Talking about water moving and people doing things is pointless ... if you can run GTA5 at 200FPS must be the code not the computations ...

i have almost the same config. and i get the same fps form 640x800 to 4k ...

BTW .... no , the eyes go up to 150 FPS , and with the "computing" done in the brain you can tell the difference up to 220 FPS .... do you really do not see the difference between 30 and 60 fps ?? something is wrong with your eyes maybe :)

Consider how much moving water there is on the map, for example.
Consider the number of moving units on the map. Limiting the size of the city to more manageable numbers will help reduce the burden on the engine and your CPU.
Remove unnecessary graphical detail such as fog, day/night and other weather effects.
Reduce the resolution and level of graphical detail.
Avoid use of any mods that require extra computations.
Whatever you do, then be satisfied if you can achieve around 30fps which is what you can perceive with the human eye.
I hope that helps.

What is the resolution of the screen you are using in both cases? Are all of your drivers up to date? What third party software is running? Do you have any unused controllers or other devices attached to the computers? Is your mouse optical and sitting on a shiny surface?
The author of this thread has indicated that this post answers the original topic.

Its mostly the game. Avoid using workshop for anything that isnt purely aesthetic as game will bottleneck on how much its able to utilize the cpu. On bright side in 20 years we might be able to run this game with 60 fps.

Could there be optimization issues, sure, the game is over 5 years old now.

Talking about things like water physics and active agents isn't pointless; they contribute to the majority of the strain on the system.

Comparing apples to oranges really isn't helpful either. Compare this game with a similar game which tracks tens of thousands of agents actively then we have a fair comparison.

The movie and television industry standardized at 24fps, gaming for the longest time was 30fps. Can your eyes tell the difference between 15-30-60fps? Of course, but the higher you go the lower real-world return you get, aka diminishing returns.

And to the nature of the OP: What is the population size, how close are you to the game limitations for things like vehicles, where are you getting low fps (downtown core zoomed in or zoomed out in a light density area), what mods do you still have installed, how many assets do you have loaded into the city?

Also, take the time to read this guide and see what you can do to optimize for the game:

If you want to increase your FPS, you can do some things in NVIDIA Control Panel.

I have a 32GB, 3600X and 1080 GTX card and I have 300mods, 925 assets.. Run at 4K resolution and run dynamic resolution at 175% and get between 25 and 40 fps.

The core issue is its not graphical related lag most of the time. You can run the game in like 360p and get same fps as 4k. (depending on gpu obviously) This game must have been hell when people had generally had slower cpu speeds.

It depends on a lot of factors. But generally if you have a 4 core processor, 32 GBs RAM, and an SSD then you are going to fix a bunch of 'CPU oprimizarion' issues. Then tweaking GPU performance will give you an added 10 to 15 FPS. At least it did for me.

If I turn off Dynamic Resolution (or set it to 100%),i get close to 50 FPS.

Maybe you don't realize that, but there are some mods on workshop, even quite popular that kills fps a lot. If resolution change doesn't improve fps it means that CPU is so busy doing other things that it has no time to prepare data to render frame quicker.
If your game runs in 13fps means that one frame takes about 77milliseconds to prepare data and render. On the other hand to get for example 60fps, one frame has to be prepared in 16milliseconds, I repeat 16ms (almost 5x quicker).
Some of the mods are poorly designed and all operations are done on UI thread, blocking other operations like frame rendering.

Now imagine that you have 5 mods where each mod eats 5ms to do its stuff each frame rendered (yes there are even worse optimized mods on workshop). They are run in sequence, not parallel, so 5 * 5 => 25ms/frame.

Game UI itself takes a lot of CPU time to refresh all components (~13k with most DLC enabled - update takes 5-25ms generally depends on CPU and RAM speed) and each mod and asset only adds own tasks to that pool which slowly makes game to crawl.

I suggest revisiting all of your assets you don't need and mods to check for any incompatibilities or performance issues (usually pointed in mod description or comments).
You can also try Mini FPS Booster, currently the only mod that speed up UI update a bit and wait for full FPS Booster.

OMG, your GTA5 game must be broke or something. I get over 3,000 FPS on my checkers game. Can't GTA5 optimize the game after all these years? It definitely has to the be the code, not the computations!

Contact the GTA5 devs and tell them to fix their broken game!

This game will max out at around 30 fps on any rig without workshop. But when you add workshop, they are external to the game and additional loads to the game. So FPS will suffer more and more as you add mods that alter the game.

Assets have a vert small impact on performance, but will hit you in the RAM dept. They consume large amounts of RAM, especially if you want all unique buildings on your map. 1,000 subscribed buildings is easily 16 GB, maybe more if you have high quality assets.
