Quake 2 RTX problems with SteamOS
Has happened with all SteamOS versions but currently I am on SteamOS beta 3.6.9
I've noticed that SteamOS is capping the Quake 2 RTX frame rate to 20fps and hindering performance. I know this because sometimes I can glitch out SteamOS to uncap the frame rate and increase performance but it's very difficult to pull off, it's what I had to do when making a Quake 2 RTX optimization mod for Steam Deck
How I noticed this: At first when I finished the optimizations the game ran fine on the preview build, I got the game running at 30fps with a dynamic resolution of 70-80% The first issue I noticed tho is when pulling up the built in performance overlay (this also helped confirm that SteamOS was the issue), the FPS would cap to 20fps and drop performance, I thought it was weird but nothing too big Then when I restarted the Steam Deck, this issue became permanent even without the performance overlay, it was capped to 20fps and dynamic resolution dropped to 40-50% (this is all at 800p, 1080p has different scales) The way I was able to glitch back the performance sometimes was by switching from preview to beta than back to preview builds in SteamOS.
I really do hope there is a way to fix this as I have been trying to show off the RT capabilities of Steam Deck and right now the software is the biggest issue for this game
