Hello, I’ve run into a weird issue when trying to play some Warframe.

When running the game all of the performance stats seems to be reporting a solid 200+ FPS but the framerate feels choppy as if I were playing on 60 FPS. I’m playing on a 240hz monitor and I notice the framerate is not at all close to 100 even though both the game and mangohud is reporting 200+ FPS.

I’ve tried running GEProton 9.6, GEProton 9.7 and Proton Experimental through Steam but nothing seems to solve the issue. I’m also using VKD3D_FEATURE_LEVEL=12_0 to enable DX12 (DX11 has the same issue) aswell as gamemoderun for any possible improvements. Note that this all persists even without any flags. I have also tried disabling the Steam In-game Overlay but that didn’t help either.

Does anyone have any information on what could possibly be going on here or anything that could help? I will post my specs below.

OS: Nobara Linux 40 DE: KDE PLasma 6.0.5 CPU: AMD Ryzen 5 5600X RAM: 32GB (2x16) DDR4 3200Mhz GPU: AMD RX 6800 XT

Update: I found out that the issue seems to be related to KDE, when running in GNOME (Wayland) the displayed framerate matches what is reported via game and MangoHud.

    Should be something like - “gamescope -W 1920 -H 1080 -f %command%” I will also note that mine tends to crash/not launch if I don’t put Mangohud arguments BEFORE gamescope. The w and h arguments are just width and height resolution, so set those to match your monitor. The “-f” is for full screen.

      I removed all of my other arguments and tried to start with “gamescope -W 2560 -H 1440 -f %command%”, when I start the game the “Processing Vulkan Shaders” steam pop-up shows up, and when I click “Skip” (as I always do) it just disappears, no error or anything, the “Play” button on steam just goes back to green.

        Interesting. I haven’t had any issues with gamescope for a long time… Back when it was new I definitely had issues running things with it… But it’s been a long time since that’s been the case. I can recommend running steam from a terminal and viewing the output after trying to run the game with gamescope. It might point you in the right direction.

          Good info, I will try this tomorrow and report back.

            Might be worth trying gamescope on another known working game too. Would help narrow down if it’s gamescope itself or the game you’re trying to use it on.

              Got gamescope working but the issue still persists. I’m gonna try launching in different DE aswell as letting shaders fully compile.

                Launching it in GNOME (Wayland) seems to fix the issue. Very uncertain what this issue was but it seems to be related to KDE.

                (Also I did not let the shaders compile, so not a shader issue)

                  Weird! I’m running Bazzite kde (so fedora based, like Nobara but with different tweaks and it’s atomic), and gamescope gives me zero problems. Might be some weird combination of software versions between gamescope and kde in your system. Or just a general kde config problem. I love kde, but all that customization can absolutely come at the price of stability at times.

                    What KDE/Kwin version do you use? Would be interesting to compare.
