I thought I make my first post in here to share my findings in overclocking processor and graphics card. I think it's better to put it in this thread than to post a new thread about this.
First off, I've got the following setup:
Core 2 Duo E6750 (2.67 GHz stock)
2 GB of Corsair XMS2 DDR2 RAM (2 x 1024MB in dual channel)
GeForce 8800 GTS 640MB (Albatron, G80 core, stock at 500/1200/800 MHz engine/shader/mem)
MSI P35 Platinum motherboard
I've had my processor clocked at 3.2 GHz since the day I got it and been completely satisfied with that. Then Black Shark comes along and really puts pressure on my processor - I read about it in the forums and realize, hey maybe I should overclock some more to see what happens?
I'm not very fond of playing games in other resolutions than my native (1680x1050) and prefer games running at at least 50-60 FPS. I prefer to use anti-aliasing and anisotropic filtering but see no real need to go beyond 4xFSAA and 16xAF.
This wasn't really tested using scientific methods and systematic variations, but some results can be seen anyhow.
Lower (initial) settings:
C2D @ 3.2 GHz
GeForce @ 645/1493/933 Mhz
BS with everything at low except texture detail set at high, no AA or AF.
This gave an overall FPS in BS of: ~30-40 in cockpit and about 50-60 FPS outside view.
Higher settings:
C2D @ 3.5 Ghz
GeForce @ 660/1528/1005 Mhz
BS with texture, scenes and view distance at high as well as heat blur on, 4xFSAA and 16xAF.
This gave an overall FPS in BS of: ~60 in cockpit and about 100-110 FPS outside view.
Conclusion:
A faster processor is definitely the biggest improvement to get higher FPS. A minor clock difference of about 10% gave a boost of almost 50% in FPS in the cockpit. I haven't tried using AA or AF at the initial settings, but I think that there had not been a significant hit on FPS, should I've used 4xFSAA and 16xAF.
I hope this information helps someone with something they are wondering.
