Game Performance Looks Laggy, FPS Counter Between 120 - 165 FPS

[nice_bnuuy]

Good evening, this is a bit of a weird question.

I am giving Linux Mint 21 a go on my gaming computer after using it for studying and programming and loving it quite a bit. However, I have done some testing with games and I am noticing some odd framerate behavior. While playing Doom Eternal, the built in framerate count hovered between 120 - 165 FPS, but during gameplay there would be moments where the framerate felt more like 30-40 FPS, but the framerate count still hovered between 120 - 165 despite the jittery looking moments in gameplay. My specs are as follows:

GPU: AMD RX 6600
CPU: AMD Ryzen 5 5600X
MOBO: ASUS B550-PLUS TUF
RAM: 16 GBs 3200 MHz

Is this some sort of frametime issue? How might I go about trying to diagnose this issue? I am somewhat new to troubleshooting on Linux and this is the first time I have ever run into an issue such as this.

Before you post please read how to get help

Need more details.
Kind of impossible to miss that " how to get help' this considering it's blue with a pink background. ( why does no one read this ..*sigh* ) " how to get help" link...step 5.

You can post that info that way via that terminal command ( i prefer inxi -Fxxxmprz ) .

or

Open your main menu ( windows logo button on your keyboard) type without quotes " system reports" , select it. left click on that " system information" button on the left, left click " copy", come back here. click that </> button ( fifth from the left right above where you type your responses), then paste it ( makes reading all of it much easier to scroll too without taking up much space on the page.

This will tell us how LM 21 " sees " and deals with your system including much graphical/driver information. Saves on much speculation for everyone.

5900x cpu + 8GB rx 580 sapphire nitro+ gpu here and doom 2016 and eternal run like a champ at 1440p medium to high ish settings at 70+ fps with very rare stutters in native linux steam.

Given you have a video card that is noticeably faster than my rx 580 worst case and average case over 35% faster...Yeah.this is not normal behavior for that game with native linux steam client with everything else reasonably accounted for with proper drivers..etc.

Turn on VSYNC. Try to match the refresh rate of your monitor with the fps. AMD FreeSync supposedly does this thing automatically. It is supported to a certain extent on Linux. I don't have an AMD gaming card currently and personal experience. You can of course manually adjust the refresh rate, for example to 75Hz and set VSYNC in-game to 75 FPS and so on...

[nice_bnuuy]

VSync is turned on, both in game and in the operating system as well from the looks of it (I don't see any option for VSync in settings manager anywhere, unless I missed something, plus I don't notice any tearing on the desktop when doing any tasks).

Understood, here is the output:

My set up is similar to yours (Ryzen 9 5900, RX 6600, B550, etc.) and while I haven't seen what you are describing in Doom 2016, I have seen it in World of Warships under Wine with DXVK. FPS stays high as indicated by MangoHUD, but game looks choppy on ultra settings (especially in port). I'm working around it in this one game by using FSR, but the game just isn't that intensive and it shouldn't be taxing my set up at all. I too have tried various combinations of vsync and freesync to no avail.

My only suggestion is to try Proton-GE by Glorious Eggroll. It allows you to enable AMD FSR on any Steam game whether it's built into it or not.
