With the push for Wayland and gbm in the driver, a feature that would assist significantly in games is the support of gamescope. Game scope relies on the VK_EXT_image_drm_format_modifier for gamescope to properly operate.
Is this something Nvidia is working on or can get started to help accelerate Wayland and gaming?
Hi jrgiacone,
we are aware of the request and it is coming soon. We are working with Valve to ensure Gamescope runs well on our driver.
Below is the link for reference.
Hi amrits, do you mind if I ask for the timeline on this? Is it within the next few weeks, months, unknownā¦? Iām thinking this could solve some of the issues on sway where the game seems to flicker due to having issues holding mouse priority, This is noticed in games like stardew valley when running at a lower fps than your refreshrate. If you constantly keep your mouse moving there is no flickering.
Personally, with card prices coming down to earth Iām looking to punch out to AMD with my next card if this isnāt remedied in the very near future. Why wait another several months for everything to (hopefully) be hammered out?
I have seen the PR, and it seems that NVidia just makes sure gamescope go on running even without the VK_EXT_image_format_modifier API, without LUT support.
Looks like the most recent beta drivers have gamescope working, not at full performance but itās a start, awesome work nvidia. I saw open-source kernal module potentially too, maybe user space is next? @amrits
Ok so you can get a proper GPU usage if you set - sudo setcap ācap_sys_nice=eipā /usr/bin/gamescope
However for some reason if you go higher up the resolutions, itāll trigger some hard fps locks and very fluctuating gameplay locked to something like 10-20fps.
Tried debugging it to no avail. Real showstopper so far.
We see this issue with Gamescope producing very poor performance. @amrits could you attempt to reproduce this issue on your end and verify whether this is a driver issue?
