I always found complicated jumps and maneuvers were much easier to hit on higher frame rates. I remember once trying for weeks to pull of a move in COD that someone else was doing and being frustrated and not being able to pull it off. The next week I bought a new video card and boosted my frame rates hugely. I hit the jump on the second try and never had a problem. I say the higher the frame rates, the more precise the head shot is.
