I’m trying to figure out how to use Gamescope specifically for HDR on my setup, but I’m dealing with some performance issues. I have an RTX 3060 mobile GPU and a Samsung Odyssey G60SD 1440p 360Hz OLED display with HDR capabilities. I’m running EndeavourOS with the latest KDE on Wayland and using the latest Nvidia proprietary drivers. I’ve managed to get HDR to work on my desktop, but when I try to play ‘Shadow of the Tomb Raider’ through the Heroic Game Launcher, the HDR option is greyed out unless I add the environment variable `DXVK_HDR=1`. Enabling it makes the game look washed out, which isn’t ideal. When I activate Gamescope, it does allow HDR to work but the performance tanked from an average of 53 FPS to 34, with added ghosting. I’m new to Gamescope and want to know if there’s a way to enable HDR without losing performance. Is it possible to render through Gamescope purely for HDR without the upscaling that seems to create this lag?

Looks like you’re struggling a bit with the setup! I’d recommend checking the Gamescope docs more thoroughly. They’ve got specific advice that might help clear up these HDR and performance issues.
It sounds like you’re hitting some common snags. First off, you might want to avoid using the `–hdr-debug-force-output` option because it can impact performance. It’s best to run Gamescope using your native resolution. If your monitor is set to its native output and you’re also rendering the game at that same resolution, there shouldn’t be any upscaling happening, which might help with performance.
You definitely don’t want debug settings messing with your config. Here’s what I’m using for my Nvidia card that you might find useful: For SDR, run `gamescope -W 2560 -H 1440 -w 2560 -h 1440 -r 170 -f –force-grab-cursor –hdr-enabled — env VKD3D_DISABLE_EXTENSIONS=VK_KHR_present_wait %command%` and for HDR the same, just keeping everything consistent. If you have FreeSync or G-Sync, don’t forget to toss in the adaptive sync flag.
Are you sure about that? I ran some tests on my 4070ti super and found that I actually got more stuttering and just a slight performance loss with Gamescope. My frame limit only registered properly on one game, too. Maybe it’s an Nvidia-specific issue.
