Game uses 100% GPU when alt-tabbed

[MysteriousAeon]

Title. The game just decides to use 100% of my GPU when I alt tab, returns to normal when I return to the game. My GPU starts to burn just because I multi task while playing this game... Devs, optimization please?

I've not had this. And I alt-tab a lot. And pay attention to my GPU.
Are you sure it's the game? Check with task manager.

Yes, it's the game. Only happens when the FPS limiter is set to "No Limit" and the game is in true fullscreen mode. Reducing the limit mitigates the issue.

Yeah, well. You shouldn't have uncapped FPS.
Then your game will just run at like 50K FPS for no reason sometimes.

I uncap the FPS and cap to 141 from the NVIDIA Control Panel because I use GSync. What kind of response is "you shouldn't have uncapped fps" ? This issue only happens when alt tabbed and is obviously an issue with the game itself.

I personally hate unnecessarily high FPS.
Unity games which begin running at like 500 fps or 15k FPS annoy me a lot.

Did you even read my reply?

Hello, thanks for your report! We have identified this issue and are actively looking for a way to mitigate it. The game is currently running at full speed when it's background with all rendering stuff, so the next step is to pause the rendering or lower the framerate to a predetermined value when being alt-tabbed .
Again, thank you again for your report!

Hello it's reasoning is simple. I noticed it too, when i alt tab, i hear loud coil whine from my GPU, because its rendering crazy amounts of Frames in game. For now, you can simply limit your fps in game options to your max monitor refresh rate (which i suggest doing anyway in all games).

for nvidia users just turn on the "background application max frame rate" in 3d settings of nvidia and cap it there. it will only cap the fps of games when they are out of focus or alt+tab-ed
