Before you ask, yes, I am using nGlide, 1920x1080, and the 120hz monitor setting (my monitor is 144hz) on nVidia hardware. Also, i am using nVidia inspector version 1.9.7.3, but I don't know how to use it / make profiles for it. Even after renaming sin.exe to quake2.exe, it still didn't work, then when i double clicked sin.exe, it showed the intro videos like normal, but i skipped them and then the black screen showed up once more. Even when running it in compatibility mode for windows XP it still black screens and plays the sound. Another thing to note: When i alt+tab and close the window, the process doesn't auto-close, and I have to close it manually. Any help would be appreciated greatly! Thanks!

Thanks a bunch! Worked like a charm!
