Performance bug: The slower the simulation speed, the higher GPU usage. Paused game eat 100% GPU

5 votes

When I pause the game, my GPU goes to 100%, as indicated by the Windows 10 Task Manager-GPU-3D. Running the game would only takes 30%-50%.
And strangely, the slower the simulation speed, the more GPU it takes. (Speed 1 takes more GPU than speed 3)

I think it's a bug.

I am using Nvidia GTX 1080 FE + AMD Ryzen 9 5950X (Zen 3)

Not a specialist but it actually may be related to that FPS has no limit at the moment, so less CPU is loaded with game logic, the more it can load GPU with drawing frames.
Let's have devs check it out and maybe merge to corresponding report later. Thanks for reporting.

I can confirm. I noticed it because several times after I paused briefly and returned, the fans of the graphics card were at maximum speed.

I thought the FPS limit was set to 60 by default? At least that's what the Steam overlay shows me at maximum.
