GH3 PC running badly on a $2000 gaming rig

Okay I built myself a gaming rig for $2000: HD 5870, i7 920 and 3x2gb ddr3 1333mhz ram and this game runs horribly while I'm running crysis on ultra high. If I force 3d clocks on the card then the game only uses about 1-6% of the card and if I don't force 3d clocks the card is at 2d clocks (157/300). I turned Vsync off in CCC and yet my game only runs at 60 FPS stuttery as hell and just horrible all over. All help appreciated.

Not sure if this'll work, but it's worth a try. Seems to have helped a lot of other people.

CCC doesn't do anything for GH3. You'll have to disable it by other means such as 3DAnalyze.

If you've downloaded 3D Analyze, just click "Select" and find your GH3.exe file. When you've got that loaded, there's some settings that you've got to apply, and here are mine for reference, and this seems to make it so GH3 runs really well without lag, but it essentially removes the background completely.

Performance Column:
Disable Lighting
Disable Two-sided Stencil

Hardware Limits (Cap-bits) Column:
Emulate HW TnL Caps

Pixel and Vertex Shader Column:
Skip pixel shader version 1.1
Skip pixel shader version 1.4
Force low precision pixel shader

Remove Shuttering Column:
Performance Mode

Z-Buffer Column:
Force 16bit Zbuffer (without stencil)

VendorID:4318
DeviceID: 592

Again, these remove all graphics except the fretboard and notes, so I'm not sure if you intend on running it with graphics or not. For me, I don't really care about having a black background. Also, I honestly have no idea what these settings due specifically, I found this in another guide and experimented a little.

The fact that the game lags at 60FPS is because of the engine. It lags even at 250FPS and above for me. Truthfully 60FPS and 250FPS are the same for human eye, your monitor also probably only updates the screen 60 times a second, so they are same, but the engine is just super bad so that's why it lags even at really high FPS.

I'm getting similar gaming rig: Core i7 930, 3x2GB DDR3 1333/1600MHz, Radeon HD 5870 in CrossFire (Crysis, you will kneel before me). Right now if I try to record with Fraps with my current rig* it lags like CRAZY, because Fraps limits the FPS to pretty low, looking forward to hopefully record HD video...

* GeForce 8800 GTS 512, Athlon 64 X2 Dual 3800+ 2.0GHz, 4x512MB DDR2 200MHz (=POS). Game runs fairly smoothly at 250-500FPS with V-Sync off and black background.
