Strange performance issue, low FPS.

[Miz]

For some reason this game maxes out at 24 fps on my computer, a fairly high-end build currently running a 1080ti as the graphics card. The graphics menu being "fullscreen on/off" and resolution doesn't exactly give me much room to figure out what the problem is either.

Anyone else know what might be the issue here?

1080 ti 7700K win 10 1703 with gsync 165hz acer predator same issue here fps 160 to 20 and card becoming really hot its really painful to play.
sry about my english lol

Does disabling full screen optimizations in the game executable’s Properties > Compatibility tab *without* the exclusive fullscreen command also fix this issue for you, Zhukov?

It has for me although the game still starts up at 22 FPS before jumping to 165 FPS as it loads to the main menu. I have only seen this behaviour in Unity games and then not all of them suggesting some kind of bug with specific versions of the engine’s borderless full screen mode, which it uses by default, on the Windows 10 Fall Creators Update.

In my experience though, Unity seems to have a lot of issues due to it not supporting exclusive full screen as standard, i.e. DSR does not work unless you force exclusive full screen, this 22 FPS bug and the infamous stuttering that affects games with large open level design. It’s not a great engine in my view for those reasons.

I wish more developers would take the time to add support for exclusive full screen or, better still, the devs of Unity itself add native support for it. I find it bizarre that it doesn’t; it’s like it was made with mobile games in mind first and PC second, which may well be the case.

-window-mode exclusive fixed my lag issues

I was getting about 40-50 fps and laggy main menu video but now it has shot up to 140-150

I am using a RX480 gpu with amd freesync 144hz monitor

Thank you whoever found this fix

Yeah, I can confirm what Doctor Hades here is saying. I tried it a few times more and suddenly out of nowhere I got a fairly steady 165ish fps, which tanked and went down to around 20 when opening the side menu (buildings, army etc) and whenever I wasn't using the default cursor but instead had a room or something selected.

The performance is all over the place and never good.

I too use a 165hz G-sync monitor. Wonder if it could be something about the g-sync?

I can 100% confirm this is due to 1440p. I recently just got a new 1440p monitor, coming from a 1080p monitor I was maxing out frames and now that I replaced my 1080p monitor with this 1440p one I get weird ups and down constantly. It's unplayable. It goes from 144fps to 23fps and then back up and down etc.

Try the solution posted elsewhere in the thread. It worked perfectly for me.

I'm almost positive that Freesync/G-sync will not work correctly without 'exclusive fullscreen'. (would explain why literally every person in here that has that kind of monitor is experiencing problems)

I've posted about this a few times on other forums for games that use the Unity Engine. Use the fullscreen launch option command for Unity Engine games.

here it is

-window-mode exclusive

It is a huuugee issue for some reason with people releasing their Unity games on steam without a 'exclusive fullscreen option'.

For some reason, the developers don't think it is that important. When in reality, it is causing enough problems that people are refunding Unity based games and the Dev's are losing money and don't even realize it.

So, definitely try and use that launch command for all your Unity engine based games.

I don’t know about FreeSync but G-SYNC supports both windowed and fullscreen games as long as you enable the option in the NVIDIA control panel. Anyway, not all Unity engine games are affected, e.g. The Last Tinker: City of Color and Oddworld: New ‘n’ Tasty seem to work fine on my system which uses Windows 10 Pro v1709. This issue has only started happening since the Fall Creators Update which suggests it might be related to WDDM 2.3 or some other changes that Microsoft have made to the Direct3D components that games use. This issue so far *only* affects a Unity Engine games; all other engines work as before but then those typically use exclusive fullscreen by default unlike Unity.

Same here, 7700k, 1080ti, drops to EXACTLY 37 fps every time i do certain things, such as mass-drop or collect creatures, or enter a fight. The -window-mode exclusive thing KINDA helps, but doesn't eliminate the issue and it still annoying. Thankfully, this isn't an first-person shooter, so its not a deal-breaker.

p.s. The game looks really-really nice, but this is the most bare-bones empty graphical options screen I've seen in quite a while.

Sorry for performing Necromancy on this post, but I'm happy to report this solution work out for me as well !
I have a 1440p FreeSync monitor, VEGA 64 Liquid + 1700X it defininitely mop the floor with the game's requirement....I too was getting a weird 20 - 30 FPS dip for no reason and it tend to stuck there just like that.....after using the method of

-window-mode exclusive

On the launch command, it fixes the problem completely. Amazing....

Thank you all so far.

I'm in contact with Unity to actually fix this problem. It would help to have some people with this issue to support us. If you are willing to do so please contact me at [e-mail]

Making borderless window fullscreen the default was intentional as this issue was not known, the performance impact normally is very low and it has alot of benefits for a strategy game that is often played with a second monitor. Making exclusive the default will likely result in alot of complaints too.

Unfortunately making it an option in the game isn't that simple and would require a launcher binary as there is no way to change the mode other than using the startup option. But this still is an option. First we will try if it can be fixed in the engine itself.

I never had any issues with borderless windowed Unity engine games until, I believe, Windows 10 Fall Creators Update (v1709) which was released in September/October 2017.

Since then, even with Windows 10 v1803, many Unity engine games exhibit odd issues with the default fullscreen windowed mode and the issue may be tied to G-SYNC which I use on a 165 Hz ASUS ROG Switft PG279Q monitor. Usually, forcing proper fullscreen mode via the -window-mode exclusive toggle fixes the weird 24-30 fps issue that can lock to that or sometimes jump between that and 100+ fps seemingly at random! Alt-Tabbing to the desktop and back can temporarily fix it but the issue comes back unless you force exclusive fullscreen.

Unfortunately, not every game works when exclusive fullscreen is forced so this is more or a workaround than a fix. Sometimes forcing exclusive fullscreen can cause a game to crash on exiting to the desktop or even display a black screen necessitating the use of Task Manager to close it down.

I suspect that the changes that Microsoft have made to Windows 10 (v1709 uses WDDM 2.3 and v1803 uses WDDM 2.4) have somehow messed up G-SYNC's borderless window support which is what Unity uses by default. NVIDIA, however, seem to be terrible at fixing issues of late so I suspect a fix may be slow in coming or never come at all. If the Unity developers can make it so that their engine supports both Exclusive and Borderless Fullscreen as standard then this issue can be fixed by a simple change of Graphics settings.

Why Unity defaults to borderless fullscreen rather than the exclusive fullscreen that every other PC engine tends to use is a mystery. Borderless fullscreen generally runs worse than exclusive fullscreen, even if only by a small margin, and it's only advantage really is that it makes Alt-Tabbing to the desktop and back much quicker. Personally, when I play a game I really use Alt-Tab (I can count the number of times I've used it on the fingers of one hand and still have fingers left!) so Borderless Fullscreen is more a hindrance these days with the framerate tanking issue.

[Doctor Hades]

Just out of curiosity, is there anyone experiencing this low 24-30 fps framerate issue who is not using either G-SYNC or FreeSync?

I suspect the underlying issue may be with those and the changes to how fullscreen works in Windows 10 to support the Game bar (making exclusive fullscreen games work like borderless fullscreen to support the in-game overlay unless you disable the fullscreen optimisation in the game's Properties settings).

I haven't try turning off Free Sync, but as I mentioned, after applying that exclusive fullscreen command, it fixes my problem. Just to be clear again I'm using a Free Sync monitor.
Then again Free Sync for my case has never been " perfect " BUT this could be only my specific monitor I can't say the same for the rest. Even til now I still get flickering in games when during loading screens. And maybe even some weird lag and such in some games.

Not really sure if it's a Driver issue, monitor, or just the game itself. My friend had an Acer Free Sync monitor he didn't have any flickering like I do. And I've already RMA it before thinking it was the monitor faulty at first but it isn't, I'm using a BenQ XL2730Z

damn, been trying to find something about this since i got this game. fixed it for a short time with messing with tabbing out and such. but yes i have a MSI AMD R9 390 GPU and a fx-8350 CPU OC'ed @ 4.5GHz and randomly at times or even loading certain area's differently i get random frame rate's. one time it could be as high as 300, other times as low as 10... but i'm going to try that command and hope it fixes it. i'll report back after some testing.

EDIT/UPDATE:
Well, ran through a few levels. so far it made the V-Sync work right, the area's that dropped the FPS bog down were not as low as before and stayed pretty consistent(on any graphics and/or resolutions, windowed or fullscreen stayed around 38-40FPS before the command it would drop as low as 9FPS which it will do that when changing the overall graphics bar but locks it around 15FPS til a new area/sub area is loaded.) and the cut scenes were finally working right(higher FPS, no desync of the audio and no stuttering) but the cut scene's matched what ever problems with the area your about to load into next. the VERY first cut scene and area you play both stayed about 39FPS. all the sub area's easily came strait up to 60. think this is a bug in certain area's honestly from how it feels, but i could be wrong. overall this command seemed to fix half or majority of my problems but the odd thing is... even though it's about 40FPS it stutters or at least makes it feel like it's less than 30FPS... unless the game is just easily noticeable with not being 60FPS or higher. not sure if anyone else notices that or not but trying to point everything i can out that may help or be information needed.
Also, i don't have any high end screens nor do i have any "sync" other than V-sync and Enhanced-sync(which is a newer sync by AMD that is ONLY useful for FPS that's going OVER your monitors refresh rates). i also haven't noticed too much heating problems while playing this game(except if vsync is off but about the same as any other game.). but i honestly don't pay attention as a game like this shouldn't be causing problems like that lol. also, i am running 2 monitors but i have tested unplugging the one and no difference.
Also, yes windows 10 has been getting a LOT of flak because there is a LOT of problems with the OS still that's greatly affecting games and even basic programs... this most recent update was even released by accident about 3 or what ever days before they planned and there was MANY bugs in it STILL i found almost a year before... such as the new BSOD(Black Screen Of Death) which was a mix of the update and even cleaning programs and driver's for the monitors them selves and everyone kept trying to pin it on the GPU driver's when majority of the time it wasn't the driver's lol. but think they fix majority of that about 2 or 3 months after the update went live. but this is why many I've come across still prefer windows 7... also... a tip for anyone having problems with windows live enabled or related games... you have to manually update the live crap by uninstalling it then finding the installer online.

1.5.1 launches in exclusive fullscreen by default and contains an Option (Borderless Window Fullscreen) to switch to borderless window.
In borderless window mode the game doesn't minimize anymore and the mouse is not caputured, intended to be used eg on a second screen or for streaming.

The performance problem due to Adaptive Sync on Windows 10 should be gone in default exclusive fullscreen mode.
