Finished this game for the first time last week, picked it up a while back in a steam summer sale, and finally got around to playing it. Its way better than i was expecting!
(not the point of this post, but it does add context to why I am late to the party)
There is a known bug on PC where if RT is enabled the game becomes unstable, random crashes where the screen freezes and the audio keeps playing.
There are many threads on Reddit and Steam forums about this, all are old, and the only solution on PCGW was to disable RT.
Anyway, I wont go into all the boring bits of how long it took, but the fix for this ended up being pretty simple:
"
- Install and Open NVIDIA Profile Inspector
- Search and open 'Marvel's Guardians of the Galaxy' profile
- Scroll down to '06 Rendering Features' section
- Find 'Experinmental - Raygen Scheduler Override Shader List' option
- Change from its existing value of 'ReflSpec_RG' to value 0x00000000
- Apply
- Open the game with RT enabled
Raygen Scheduler Override controls the way RT pipline handles information, by removing ReflSpec_RG expect a 1-2% Framerate drop, however the game will be stable as it returns to using the developers intended pipeline, Rather than NVIDIA's override.
"
Testing:
(Start of chapter 6, when flying into knowhere, was a consistent repeatable crash for me) outside of that, all chapters can randomly just crash, including chapter 1, but harder to consistently replicate.
Note:
-If you're not familiar with Nvidia Profile Inspector, it just exposes driver level profiles and options so you can change them yourself rather than NVIDIA. Its downloadable from Github.
-I have submitted an edit to PCGW so others grab the fix from there or this post, either way.
Hope it helps someone who wants to enjoy RT on modern hardware in this great game :)
