@kisak-valve Recommended to make this a compatibility report and not a whitelist, Have discovered that both this and Vegas 1 have a "Don't recognize interface name: SteamUser021" error, planning to test whether or not https://github.com/ValveSoftware/Proton/pull/3886 would fix this and Vegas 1 too.
Hello @CDAGaming, please add PROTON_LOG=1 %command% to the game's launch options and drag and drop the generated $HOME/steam-$APPID.log into the comment box.
I can also confirm that #3886 fixes Rainbow Six Vegas 1 Launches, while Rainbow Six Vegas 2's shows a black small screen then fails, but gets further then the original error
The Log above is the original Rainbow Six Vegas 1 Error, while the bottom log is from after applying #3886 from https://github.com/stevenlafl/Proton/releases/tag/proton-5.0-7-alyx-2 to Rainbow Six Vegas 2
Works fine for me on one computer, and not on another with near identical specs (different CPU 5820k vs 5960x, everything else is the same).
I tested with Proton 6.3-6 and Proton GE 6.14-2, no difference, just shows application load error 2:00000065558.
I've attached the logs:
