[2024] Nvidia graphics driver 551.23 does not function properly with Darktide

I think the issues are separate. For your buddy, it sounds like his Anti-Virus is quarantining part of the Darktide installation. I expect this is the Darktide.exe, and he is using Avast, based on similar reports I’ve read recently.

I understand you have some overheating issues which is usually hardware-related. Have you experimented by rolling back to the previous driver?

Certainly try deleting your user_settings.config if you’ve manually edited it.

You will need to disable Steam Cloud Saving to start with, otherwise it will automatically restore the user_settings.config:

1. Navigate to your Steam library
2. Right-click Darktide
3. Select ‘Properties’
4. On the ‘General’ tab, scroll down to ‘Steam Cloud’
5. Disable ‘Keep game saves in the Steam Cloud for Warhammer 40,000: Darktide’

Assuming you’re using DLSS, there is no need to use NIS, from what I understand.

I think this might be outside of what we can help with unfortunately - I would recommend contacting NVIDIA as they will be best equipped to advise on next steps.
