INVESTIGATION: Poor Performance & Power Draw Issues Impacting AMD Radeon 6000 - 9000 Series GPUs

Warhammer 40,000: Darktide Performance Feedback
85

Hi Julia,

I’ve found form all my testing that having SAM / Re-Bar (same thing) enabled impacts the performance of Darktide negatively.

This is ALSO the case on NVIDIA GPUs as well. Though NVIDIA enables Re-Bar on a PER GAME basis at the driver level, whereas AMD is either always on, or always off. NVIDIA has Re-Bar disabled for Darktide, and when forcing it on using NVIDIA profile inspector, this caused performance issues.

My findings for having Re-Bar / SAM on is as such:

  • The max framerate experienced will be higher, but the minimum framerate with also be lower. (You don’t want lots of ups and downs in FPS, you want it consistent). This also introduced more stutters.
  • The only time this was NOT the case, was with driver 23.11.1, which was the last driver that “Just worked” with Darktide.
  • My personal optimsation settings I did in a separate post mitigates MOST of these issues, but if Darktide is your main game, I would reccomend having SAM / Re-Bar off if you use an AMD GPU.

Hope this helps.
