Game Benchmarks: Crysis

Gaming With AGP Graphics: Overclock That CPU!
By

Here's where we expect things to get interesting. Will the overclocked CPU unleash more performance or will Crysis be too bottlenecked by the graphics subsystem to show any gains?

There's a lot of data to sift through here, but the most obvious conclusion is that the Athlon X2 3800+ severely bottlenecked the AGP Radeon HD 3850. However, the CPU change doesn't seem to have much of an effect on the Radeon HD 4650 cards. Apparently, Crysis was already choking these graphics cards, even with the Athlon X2 3800+. Let's see if upping the physics detail has any effect:

If you look at the previous results, you can see that upping the physics detail has almost no effect on the simulated Athlon X2 5000+ CPU. Compare this to the Athlon X2 3800+ CPU, which definitely took a frame rate hit when physics detail was increased. This indicates that the higher-clocked CPU is shifting the bottleneck back to the graphics cards.

Also, as the resolution is raised, the bottleneck quickly moves to the graphics card. This means that the gains from the faster CPU had the greatest impact at 1280x1024. Having said that, the AGP Radeon HD 3850 was able to leverage its higher graphics performance across the whole spectrum of resolutions.
