Hi Vangel76,
I had this happen a little while ago when I enabled DX12 on my machine. I found it was due to the project’s Antialiasing settings. on my machine, I was trying to launch with MSAA enabled and had to change it to Temporal AA. I create a youtube tutorial about it which might help if you are unsure about how to do this.
Hopefully, this should help.
Thanks, .
