As your hardware is well up to the requirements for those games, I must
presume there is either a driver problem, or another task is kicking in and
taking over for a moment. If the 'jitter' happens at the same time in the
game, then I would suspect drivers, if it is unpredictable, I would suspect
something else competing for the CPU (although don't rule out drivers here
too).

Get yourself the latest driver for your 7600GT, then see if the problem goes
away. If it doesn't, then close all other applications and investigate
processes that are running at the same time as the game. Search the web for
each process running and kill and non-system processes and see if the
problem then goes away.
