Probably win7 is cheating you..use display changer II to ensure desktop is @60i. An alternativate is create a custom modeline without 50hz, for example 686x483@60i
interesting ,
Mame & others sega model 2 model 3 is running fine , so its the desktop that isnt really 640x 480 60i then?
dolphin (triforce) i cant get to run 60 either fullscreen (maybe thats a another problem)
i will install crt emudriver again then try the display changer II to see if its fixed
have no knowledge of custom modelines i did notice if i put my desktop to 640 x 480 it has effect with certain emulators [Supermodel i run at 544 x 480 resolution] if i use a higher desktop res the supermodel screen isnt as good , duckstation also i set it to a high res i think 1280 x 240 duckstation would run 50 fps aswell
If i put the desktop to 686x483@60i will it have influence of the emulator res
