[News] Gamescope added support for ReShade shaders on Linux / SteamOS (www.gamingonlinux.com)

The documentation for Gamescope has now been updated to note it supports a "subset of Reshade effects/shaders" and so this provides an easy way to layer "shader effects (ie. CRT shader, film grain, debugging HDR with histograms, etc) on top of whatever is being displayed in Gamescope without having to hook into the underlying process".

To be clear, this functionality isn't available in SteamOS yet but hopefully it will be coming soon.

This is the best summary I could come up with:

Gamescope, the microcompositor from Valve that is used on the Steam Deck that can also be used on desktop Linux, just got a major upgrade.

The documentation for Gamescope has now been updated to note it supports a "subset of Reshade effects/shaders" and so this provides an easy way to layer "shader effects (ie.

CRT shader, film grain, debugging HDR with histograms, etc) on top of whatever is being displayed in Gamescope without having to hook into the underlying process".

Using Reshade effects will increase latency as there will be work performed on the general gfx + compute queue as opposed to only using the realtime async compute queue which can run in tandem with the game's gfx work.

Using Reshade effects is highly discouraged for doing simple transformations which can be achieved with LUTs/CTMs which are possible to do in the DC (Display Core) on AMDGPU at scanout time, or with the current regular async compute composite path.

Pull requests for improving Reshade compatibility support are appreciated.
