Question by CSEJereH · Jun 04, 2020 at 06:16 AM · performance optimization

Build performance is better when game window is out of focus

We are facing this rather weird issue. When the game window is active the performance is stuttering around 30 fps, but if I open new window, e.g task manager and the game is running in the background out of focus, the frame rate increases significantly.

Enabling VSync fixed the issue on a different project, but doesn't work with this one.

We have two screen setup and two different builds running on each screen.

Any ideas what might cause such behaviour?
