Question Blank screen on games’ startup

[Loopsuit]

Hi!

My issue is, when I have both integrated graphics and gpu enabled in device manager, a lot of games have a blank screen on startup. If one is disabled, the games will work but are lagging. I have tried updating both drivers, to no avail. What could be the reason for this?

Specs:
CPU - Intel® Core™ i5-12600K
GPU - Radeon RX 6600
Integrated graphics - intel UHD graphics 770
Motherboard - ASUS PRIME Z690M-PLUS D4
