  • I had this issue when I was using -F fsr, you could try disabling that if you’re using it. I also have to do ENABLE_HDR_WSI=0, since I have that enabled for MPV but setting it to 1 makes Gamescope break.

    My current launch options are ENABLE_HDR_WSI=0 DXVK_HDR=1 gamescope -f -H 2160 --force-grab-cursor --hdr-enabled --hdr-debug-force-output --hdr-itm-enable -- env MANGOHUD=1 %command%. I may also have ENABLE_GAMESCOPE_WSI=1 set as well, you could try that.

    Using NixOS with Linux 6.8, Plasma 6.1, gamescope-wsi_git, and an RX 7600.















  • My current MPV config is here (in the NixOS syntax but it should be understandable). The profile is what applies the SDR->HDR effect, only if the video is in SDR.

    I have target-peak set to 550 nits which seems okay, but I have control + scroll wheel bound to turn it up and down. If you go to 200 or below it seems to disable the effect, which is good for 2D animated content. EDIT: even with inverse-tone-mapping disabled this still messes up the image. You need to actually disable the inverse-tone-mapping and then set target peak to either auto or something above 200 in order to actually disable it. You can check with --tone-mapping-visualize.

    I also generally turn the saturation up to like 15 or 30 or something since it can look washed out. Gamma looks best at 0 generally, but in dark scenes to combat blooming I might turn it up to like 5 or 10. I haven’t messed too much with the tone mapping curve but I’m using what the documentation says is recommended so it seems good.


  • I have a Mini-LED HDR monitor (Acer XV275K P3) and it looks great. It gets super bright with black blacks. I didn’t want to risk burn-in, it covers the full 1000 nits that most HDR content expects, and it was only $550 which was quite a steal. There’s occasionally a little blooming in dark scenes in movies, but in games it never gets that dark and there’s mostly very bright things instead.

    I have HDR working on Plasma 6 with an AMD gpu on NixOS, although recently Gamescope/Steam has been a bit bugged. MPV still plays movies perfectly though. I even set up inverse tone mapping so SDR videos get converted into HDR, which looks a bit better than normal SDR imo.
