Symptoms

When playing Solo, the game runs incredibly smooth. When playing in duos or trios the game is hovering around a solid 30-40 FPS. Editing in-game settings doesn't seem to affect the FPS at all. If your teammates die and leave the game, the FPS jumps back up to normal and smooth.

Reproduction

I can confirm that I am experiencing the exact same issue.

Only an issue for me after the newest DaD patch 2024/12/27 Patch:6.7#Hotfix 75. No issues before this patch on both Steam and Lutris

Launching Blacksmith launcher through Lutris (I have tried steam aswell with no difference).

I have tried disabling/enabling the following options:

• Many different Proton versions
• DXVK
• VKD3D
• D3D Extras
• Esync
• Fsync
• Feral gamemode
• mangohud/gamescope
• all kinds of environment variables
• In-game launch options (-USEALLAVAILABLECORES, -dx12, -dx11 etc.)
• Disable Lutris Runtime
• Prefer system libraries

Nothing seems to fix the issue. Seems to be related to fetching of teammate data (hp, buffs, class, name) as the performance comes back to normal GPU utilization when teammates leave the game, or playing solo the performance is amazing. Solo is still multiplayer which leads me to think that fetching the teammate data is the issue. It doesn't seem to be the UI elements, as hiding the UI via in-game keybinds has no effect on the performance issue.

Newest update to Dark and Darker has made this issue even worse. Using Mangohud, I was able to see that CPU and GPU utilization fluctuates from 30% up to 60% usage, but it quickly drops back down.

Frame Latency has gotten worse when not even in an official game. Sitting in the lobby gives me from 60ms to 140+ms latency on my frames.

Starting to feel this is more of a Dev issue on the Dark and Darker side.
