Serious Sam 2

Serious Engine 2, the game engine for Serious Sam II was developed alongside the development of the game itself, and was a brand new revision of Croteam's prior Serious Engine that was used for their previous games, such as Serious Sam: The First Encounter. The more advanced features of the engine include detailed refraction effects, high-resolution textures, high-dynamic range lighting, and light bloom effects

Running Serious Sam 2 v2.070 at 1600x1200 makes for impressive game play thanks to high-dynamic range and a graphics engine that still looks good today.  At 1600x1200 the AMD Athlon 64 5600+ takes the lead, but we know from testing this game for a number of years that each map hammers system performance differently.  On the map Branchester the AMD 5600+ has a 50 frame per second lead over the Intel E6300.

Keeping the settings the same and moving over to the map Greendale (which is the screenshot posted above) we can see how a bigger out door scene runs on both processors.  The scores are much lower with just 22 frames per second between the two procesors.
