Latest nightly build, updated cores, Win10 / i7, 1660 Ti, updated video drivers, etc. Happens in windowed/full screen modes. Never had this issue before, tried a zillion settings nothing has worked for me. When I load a PSX game using the Beetle PSX HW core it flickers black screen and then during gameplay its flashes as seen in the video below. For Saturn using medafen core its extremely slow and noise crackles like mad. In game play its extremely slow as seen below. I have no issues in PC games, Dolphin, PS2, MAME, PSP, etc.
PS1 SAT
Thanks for any help, its driving me mad and can’t use either system.
