I’m trying the Sonic 2 multiplayer test that @Alphanu uses to demonstrate interlaced switching working correctly. However, I’m having trouble getting that to work on my Nvidia card. What ends up happening is that every time it switches into or out of interlaced mode, the image gets squished in various ways. Sometimes horizontally and sometimes vertically.
Eventually it will come around back to the correct resolution but the next switch to interlaced will mess it up again.
A quick remedy is to turn on a Custom aspect ratio but that messes up the rest of the game that’s in progressive, giving me the same image problems.
