my VRAM is fine however when is try to change fixture materials my GPU overloads saying it’s out of memory.
This might be a corrupted file issue. Verify your Steam game files. If the fixture you are trying to change is from a mod, then it may became an issue after updating the game. Reinstalling the mod or not using it at all will be a solution. If nothing of this isn’t working, try reinstalling the game. I am simply giving some general things you can try. Without any more details, I doubt you can get better advice. You should try asking in the Discord server for a more immediate and helpful advice than this one. Good luck
Can you give us a rundown of your PC’s hardware specs? Thanks.
