It's sad, I used to think HL2 was optimized really well, but after doing a ton of benchmarks I realized that it really isn't =\. It's sad that I can get higher FPS in games like Crysis and Oblivion on the highest settings than I can HL2.
Of course, I think the benchmark for HL2 is borked for me as the first half of the level has a slight pink tint to it similar to those that you'd see if a map had missing textures
. I can still see the textures, but it all has a slight pink tint.
I get about an average of 320 FPS on the highest settings in World in Conflict.
