Hi @Austin001316. Unfortunately there is not a whole lot of information to go of off here. Could I please ask you to enable Aftermath and reproduce the crash again? To enable Aftermath please change the line "#dxvk.enableAftermath = False" to "dxvk.enableAftermath = True" in dxvk.conf. After this is enabled and you experience a crash, a crash dump file might be created in the same directory as the executable. The file extension should be ".nv-gpudmp". Please upload that file to help us diagnose the issue.

By beside the exe, you mean hl2.exe correct? I enabled aftermath but did not find any files related to crashing, .dmps, .nv-gpudmps or anything else that stood out. I tried to check the other folders as well but did not see it anywhere.

The line was already there in my .conf, so I uncommented it. After uncommenting it I ran the game, it crashed, but no dmp.

I tried running again, and this time got a different crash. Instead of the popup telling me to collect any logs and submit here, the game just disappeared, no popup and still no dump.

[Austin001316]

Third time running it now(the crashes seem to be more frequent when doing challenge levels/just going faster)

Got the popup this time.

No dumps I can see.

Only these logs in the log folder the popup points me to, they will be attached just in case.

I also added NvRemixBridge.log that I found in ".trex" folder.

Hey @Austin001316 - thanks for the update. Would you please try updating Remix to the most recent top of tree build from main?

Here's how to do so, if you're not familiar:

• Download and install the latest full release, 1.2.4 at time of writing, then extract the files into steamapps\common\PortalRTX\bin and overwrite any pre-existing files
• On the dxvk-remix actions page, click on the most recent entry with a green check mark
• On the next page, in the Artifacts section, click the 'release' version of the x64 package to download it
• Extract those files into steamapps\common\PortalRTX\bin.trex and overwrite any pre-existing files

Then see if you can repro the crashes you've been experiencing. Please let us know how it goes - thanks!

Still crashing after the changes, this one the game froze as entering a portal. I've attached a screenshot of the last rendered frame.

This one did include a .NV-GPUDMP, I've attached all logs and the dump.

bridge32.log
bridge64.log
remix-dxvk.log

Github did not allow me to directly attach the gpudmp, so i have uploaded it to mediafire here.

Do this :Your game is crashing because DXVK is being loaded into Portal RTX.

RTX Remix cannot run with DXVK — it causes Present() to stall and freeze.

Go to: I:\SteamLibrary\steamapps\common\PortalRTX\bin.trex\

Delete these files: d3d9.dll, dxgi.dll, any dxvk* files/logs.

Restart PC → run the game → it will use native D3D9 and stop crashing.

[Austin001316]

Upon deleting "d3d9.dll" the game runs at 4 fps max. I tried again today with d3d9 and it crashed once more with a smaller gpudmp file, and this crash caused both of my monitors to go black before coming back.

Hey @Austin001316 - have you tested Portal again on the latest Runtime build from the main branch, as per the comment from a few weeks ago? If not, please give it a go with a fresh install/update of Remix and let us know if the crashes persist. Thank you!
