What worked in my case is to set scalability “on” in target hardware, i also set directx 12 as default rhi.
First I changed Tdr Delay and disabled nvidia mpo like someone advised but this didn’t solve the problem. I didn’t revert these settings back to default though.
By the way I have a gtx 1060 6gb and haven’t geforce experience.
I3 7100.
