Abnormal GPU usage
New, WishlistPublic


GPU temperature and fan speed is high when at the main menu screen (with top down view of the map) but as soon as I go into a mission especially multiplayer mission, GPU temperature and fan speed decreases. FPS is also affected.

I can confirm this because I have MSI afterburner installed and enabled software auto fan speed control.
It will adjust my gpu fan speed according to the gpu temperature.

Steps To Reproduce

Just run the game.
If you have msi afterburner, enable the auto fan speed control and observe the behaviour of your gpu temperature and fan while in main menu screen and while in a mission.

I thought GPU usage is suppose to be low while at the main menu and increase when you are playing in a mission. But in my case stated above, it was the other way round.

Are you starting with -world =empty?
If I put every option at minimum with -world =empty I get 800 FPS in the menu.
Nothing strange about that as there is no frame limiter and there is almost nothing to render.
You can enable vsync to limit FPS to 60.

"Are you starting with -world =empty?"
In my case, yes and I really don't think this invalidates the bug report.

There is no FPS limit in main menu. Which is the cause.
