That doesn't explain why the original poster would get more FPS with
VSync on.

I've read benchmarking articles where disabling vsync could increase
your FPS by ten or more. And they were on newer systems. But it wasn't
on the Unreal engine. I believe it was on Quake2. And yes, you could
easily get 60+ Hz with monitors in those days. I believe I had mine at

Anyway, I can easily benchmark my UT and will be giving it a try with
this option on and off.
