I have been testing the demo out a bit in the respects to the effects of overclocking to the performance in the game. What I have done is overclock one component and one component only at time then ran a full cycle of GPU tests for the 64Bit version of the demo. The results are rather strange I must say but here they are as follows.

SPECS:

Intel Core 2 Quad Q6600 1066FSB
2X 1GB Geil Black Dragon DDR2 800MHz (4-4-4-12)
Asus P5N-E SLI NForce 650i
Nvidia GeForce 8800GTX 768MB
Windows Vista Ultimate x64

The Crysis demo was ran with all the settings set to ‘very high’ bar the shadder setting that was lowered to ‘high’. The resolution was set to my monitor’s native resolution of 1680X1050 with anti aliasing disabled.

BENCHMARK RESULTS:

1. On my first benchmark I tested out my system with all the components at their default specifications. The average FPS score I got on crisis was 22.92 FPS.

2. My second benchmark was with the memory overclocked from 800MHz (4-4-4-12) to 1066MHz (5-5-5-15). The average FPS went up a little to 23.36 FPS.

3. The third test was with my graphics card being overclocked from its stock settings to settings identical to the 8800Ultra. The results where strange with it not scoring much more than the ram overclock 23.57 FPS.

4. My 3rd overclock was done to the quad core CPU that was overclocked from 2.4GHz per core (FSB 1066MHz) to 2.7GHz (1200GHz). The results were by far the best out of each component overclock with the benchmarking results showing and average of 25.34 FPS. Being the biggest increase to the game by far.

I don’t know what this means but for some reason the graphics card being overclocked has had next to no effect on the game, nor has the memory. While the CPU overclock has had a 10.55% increase over stock speeds while the rest have not even reached 3%. Does this mean that the demo is extremely CPU bound just now, or has it got something to do with the rumours I have been hearing about the demo not utilizing all the cores?

Does anyone know more?

I think not utilizing the cores, I get like 20% usage on 1 core and a few percent on the other cores (which is probably just the windows crap that runs in the background).

These are my benchmark runs, at high, you can see the CPU benchmark doing better than the GPU bench. This is probably do to Video RAM, as I have the 320MB.
