There is a checkbox in Editor → General → Miscellaneous → “Use Less CPU when in Background”
And it’s work great! Both CPU and GPU are relaxed when editor is not an active window, can the same result be achieved with packaged game?
I tested, both in PIE, and packaged game, when game is minimized and not active, it’s still uses the same amount of CPU and GPU…
Thank you in advance, I think it’s a really important issue to solve, hope for some useful solutions!
