3440x1440p locked at 40fps?

[moparhippy420]

Ok so i just bought a 34 inch ultrawide 1440p/165hz monitor. First thing i tried was this game, and for whatever reason i cant get past 40fps. Prior i was on a 1080p tv, and had everything maxed out, running pure and csp.

I tried messing with settings, from lowest to highest and it made zero difference. Also tried acc, which a few quick practice laps on an empty track i was able to average around 60-70ish fps. Tried ghost of tsushima and red dead 2, changing no other settings except for 2560x1440 to 3440x1440 (my "main" gaming monitor is a 32in 1440/144hz) and noticed fairly close to the same performance.

I also can run ac in vr at higher framerates then i am on my ultrawide. All of the above is for referance, and reasons why i just dont by that "my system is too weak", not to mention ac is going on a 12 year old game.... I also use to run ac at 4k on a 4k tv at 60fps....with my old rx580....

As for my system specs:
Ryzen 3600
Rx6600
64gb ram
M.2s

So, any clue as to what the issue can be?

Make sure you are actually using your GPU and not your integrated GPU.
Make sure you are plugging the ultrawide inside the GPU and not anywhere else.
Make sure your desktop settings are set correctly and in your control panel you have correct setup.
Make sure you update your drivers.

I think you are also having a major bottleneck in your CPU, not a fan of your setup.

Umm...my cpu dont have intergrated graphics, so yes my monitor is plugged into my gpu. This aint my 1st pc.

Window settings set to correct resolution and refresh rate, drivers are up to date, if the werent up to date enough for a 13 year old game, i would be having way more problems then just this....

Also, my cpu is not a "major bottleneck" for AC, or anything else i do or play....especially at these resolutions....imagine thinking ANYTHING ryzen would be a bottle neck on 2013 assetto corsa...🙄 Yet still run everything else fine.

It kind of sounds like you are just regurgitating things you have heard before and dont really know what your talking about, just to try your end goal of bashing my system at the end.

But thanks anyway i guess.

CSP / pp filters like Sol, can have issues where they are stuck at low ish framerate, usually accompanied by jittery frametimes, try to full reinstall those. And make sure to try disabling any background apps that could be trying to hook to the game. From AV, through video recording/streaming, down to peripheral HUB software. Heck there was a bug in corsair keyboard drivers that caused something similar some years back.

I've also seen a case where CM itself was causing that when it was preloaded to be shown while driving. Afaik this is fixed now, but yeah just to show the scope of what could be wrong... a fok ton, so keep chipping at it! gl!

Did you try setting borderless fullscreen and disabling vSync in CM yet? vSync can have undesired results like half refresh rate at times.
Incorrect installation (not installing it manually) of Pure and such can also cause framerate issues.
Maybe someone woth VR can chime in on rather any tools/app settings cause it.

Yeah, your PC should be fine. AC is pretty damn light even with all the mods unless you try to fill up Le Mans or something with AI. Otherwise CM, CSP, Sol/Pure, and assorted mods create too much room for user-error so it is probably something dumb.

I have not tried borderless windowed yet, but will give it a try. Vsync is off in CM, though i AM running with freesync premium on. I havent had any issues with csp/pure on the current version thats installed, though this is clearly a specific "ultrawide" issue, so i wont immediatley rule out the possibility thats something got borked and is just now presenting itself in 21:9.

Ill try running in borderless and if no luck try a clean reinstall of csp and pure. See what happens.

I tried it with the filtering setting at default as well, with no pure or sol running. Also tried launching the game through steam itself, instead of CM to try "bypassing" any issues it may have caused, and nothing helped.

Im gonna try running in borderless to see if that helps as a previous poster said, and if not then yeah, i think im gonna try a clean full reinstall of pure as well. However now that you mention that past issue with CM, one weird thing i DID notice was on the 2nd or 3rd try, when i tried launching CM, it was super laggy and pegged my cpu useage at 100%.

Never seen that before. I had to close through task manager to kill it. It did it twice i think and launched normal after that. I have auto updates on, maybe it updated versions and something is wrong with a new version?

This is a long shot, and you probably already know about it, but maybe that tolerant fault heap bug got you?

I hope its something simple like fullscreen setting, or driver in need of reinstallation...

but if not... CM is integral part of the game now, if something lags it, there is good change it will also lag the game. So could be antivirus or or rendering of CM window being broken etc.

Just for clarity of testing, when you install CM with CSP, the kunos launcher will load up CSP as well, even with CM not running. So if you ever want to compare vanilla to modded, you gotta rename dwrite.dll (in games directory) so the mod wont start.

Oh and Johnny has a good point above, FTH was plaguing AC for a while.

Ah ok i didnt realize once its installed its pretty much always there and running, even launching through steam "normally".

Ive honestly used CM so long at this point i dont remember when the last tine i actually booted through steam was lol. Im gonna watch that vid that was posted and see if thats the problem i may be having.

I actually dont think ive had this issue before, so im gonna check out this vid, thanks! Your right, it could be a long shot, but at this point that seems to be all i have 😭

Ok, so, after some more digging and troubleshooting, i THINK i figured out whats going on here. I decided to switch monitors to my 32 inch 1440 16:9 and run the benchmark, as all my benchmarks on my ultrawide were roughly the same vs my standared monitor. I wanted to try ruling out any potential issues with the 21:9 aspect ratio.

So, benchmark, getting about the same. Some digging later, i find out that everyone says turn off extrafx in CM. That apparently its meant only for screenshots and is basically like a "reshade ray tracing". That turning it off was doubling peoples fps. So i go and click it off, run the benchmark again and 90-100+ fps.

Still gotta test it back on the ultrawide to be sure but seems like thats what was killing my framerate. Or at least a big part of it. Guess when i was running in 1080p i was just brute forcing it and got a solid 60, and maybe its disabled when in vr? Its still kinda funny that after all the troubleshooting it just took one click to double my fps.

I saw a mention about it but if I recall I been using it without issue though I am not sure what the settings are since I havent played in a while.
Comments mentioned they unchecked it because it was demanding so I figured nah that couldnt be your problem.

Maybe its bugged im not sure? I know i ended up getting in the 50s-low 60s with it on on certain "restarts", but thats still far lower then expected all things considered, and it wasnt concistent. It was just a couple times.

So...idk 🤷‍♂️ off seems to put me in the 100 range so later today ill see how it works and go from there. Maybe something is still borked with the install or something.

ExtraFX destroys framerates as its an additional rendering pass, I have a 3090 and it tanks my framerate @ 7680x1440 (though it looks so damn good).

Disabling it literally doubles my frames. Probably why its disabled by default.

My spare rig is a 3440x1440 monitor and its fed by a 5600xt with a 5600X, and it gets great frames, so you shouldnt have any issues with a 6600.
