Serious Sam 2
The first edition (or should we say encounter?) of this game was quite the hit among the gaming community thanks to its amazing graphics and plentiful gags. Visually, the most impressive new feature is HDR rendering, which is supported by the GeForce 6, 7 and ATI Radeon X1x00 families. It makes reflections and lighting effects look much more realistic, not to mention much better. The Radeon X1800 XT can really pull ahead of the field with HDR rendering enabled.
