Failed to create a D3D device

My previous report as a game faliure was due to corrupt files, not Proton. I used "verify integrity of game files" in its settings and TYJ it works!
Frequent crashes
Frequent crashes seemingly related to placing or going though portals. Also crashed in between levels.
Too slow to enjoy
Unplayably slow, even on lower than low settings
Perfectly playable with V-Sync enabled
G-Sync is not engaging, leading to major tearing

See Portal RTX to know how to start this mod.
gamemoderun mangohud PROTON_ENABLE_NVAPI=1 %command% -autoconfig
The launch options seem to be required for functionality. performance is roughly on par with Windows, with DLSS averaging about 90fps in 1080p 80ish in 1440p.
Read the title.

Need launch options, otherwise won't run at all
PROTON_ENABLE_NVAPI=1 %command%
I've tried just playing with the default Proton (no dice), then found this page recommending enabling NVAPI (thanks guys!), tried current Proton Experimental and Proton-GE 8-3 - every time the same issue: the game randomly hangs every few minutes. You have to kill it externally and restart, and hope it even saved (first time there was no save, so I had to listen to the whole intro again, then raced to some checkpoint before it crashed again ;))
The whole idea of adding RT to such a technical mod is just wrong anyways. If you're a gamer, don't wait for updates. Skip this title and try the non-RT version.

Missing views through portals. Camera offset position (same as for Portal RTX).
It is necessary to append some settings to “Portal Prelude RTX/dxvk.conf” else the game will cause GPU hangs and (usually) resets.

if i went below my native res in fullscreen the window would be very messed up, worked fine in Windowed
Be careful about adjusting your RTX settings while in game, do it in the lobby or your PC might freeze.
You need PROTON_ENABLE_NVAPI=1 to launch the game.
Use -autoconfig to fix the resolution on startup.
After some tweaks i made it work, but as a 3440x1440 144hz gamer the fps is just too low, even after tweaking the RTX settings
The T Posing makes it difficult to play the game - it's playable but often your view is obstructed by the character clipping through the cam
Text in menus was off, also character was T Posing causing clipping issues.
