While alt-tabbing and minimizing the game my GPU reaches high load values (in Fullscreen and Windowed modes, thanks to @J_P)
This problem occurs while on the main menu:
and on all of the minigames too; Minigolf picture (same happens with the others):
Strangely this problem does not occur while playing on the Plaza:
I don’t know if it’s a known problem or if it’s just about optimization… after searching for similar topics it appears that nobody has ever reported such issue and I’ve decided to mention it just in case.
Just tested this, same here. Happens if you alt-tab while the game is in true fullscreen mode. Doesn’t happen with borderless window.
Condo cranks it to 99% in an instant.
CPU: Intel i5-4670k
GPU: NVIDIA GTX 980 (364.72, not the latest drivers)
OS: Windows 8.1
Edit: Forgot to try windowed. Same as borderless, no GPU usage spike. So it’s just fullscreen, for me at least.
