Read the info on performance. Switched everything (other than what needed to be left on) off or to low, resolution down to 1080p.

Tried GeForce experience ‘optimized’ settings for Darktide.

Weirdly changing the settings lower than GeForce recommended ‘optimized’ doesn’t seem to make a difference to the FPS. 4k or 1080p the FPS stays the same!

I have anRazer egpu and a 3090 card. I get high FPS on other games, even things like ‘Control’ in high rez with ray-tracing on high. I’ve also never had issues on the Vermintide 1 or 2 games.
