I have found that Lock-on is the most demanding currently available game by
far. Not only does it excercise the GFx, it is also heavy on processor
resources and memory. I have found that this game will create artifacts on
my overclocked card even when benchmarking software (3DMark, etc) suggests a
stable picture, whiich suggests lock-on is trashing the graphics even more
than the benchmarkers.
Its also pretty hard on the player's patience though - hard core flight
simulator. Not a game you can pick up in an afternoon, compounded by no
out-of-box printed manual and it is a little buggy even after the current
patch
