Doing that won't turn off Desktop Composition (the forced vsync) in Windows 8.1. As far as I know, switching to the Classic theme in 8.1 doesn't turn Desktop Composition off like it does in 7.
If you're still curious on disabling the DWM stuff in 8.1, check out this link. I still don't recommend it unless you know what you're doing.
But again, I might be wrong on my assumptions. I'd wait for more feedback from someone else.
