Framerate drops to zero while using Razer Viper 8K Mouse

Warhammer 40,000: Darktide Bugs
1

Issue Description:
While using a Razer Viper 8k, whether in main gameplay, menus or during cutscenes, the framerate drops to zero if the mouse is moving at anything other than a very slow pace. Works fine with a different mouse (Razer Taipan)

Steps to Reproduce:
Plug in Razer Viper 8KHz (RZ01-0358)
Start game.
Move mouse in wide sweeping motion from side to side
Observe that sound/music continues to play, but visuals stutter or freeze. If done in character select screen, note physics bugs, like chains flopping erratically after ceasing mouse motion.

Platform:
Steam

Approx. Time of Issue & Timezone:
2022-11-21T08:37:00 UTC

Reproduction Rate:
100%

Thank you for your report. Any chance you could upload your user_settings.config file and launcher log?

You can find these by doing the following:

  1. Press the Windows key + R
  2. Enter %appdata% within the search input and select ‘OK’
  3. Navigate to AppData\Roaming\Fatshark\Darktide\

Update:
I was able to resolve the issue by setting the polling rate for my mouse to 2000.
When it’s set to 4000 or 8000, I actually get minor performance issues systemwide, but it’s dramatically increased while playing Warhammer and so it’s the first place I noticed it.
