strange thing

This sounds crazy but my 5600ultra actually runs better with 2xaa than without? Benchmarks show the card losing points as i expect but when im playing games,they run smoother very noticable. Anyone have this experience with their video card?

That's the way it was designed. Your 5600 Ultra is basically a DX9 Ti 4200 that doesn't suffer from a huge performance hit with eye candy enabled.

if you turn vsync on with 2xaa off it will be smooth hehe, but why would you want to turn it off
