Setting help for PCX2 9.7 Fight Night Round 3

[npbsurfr]

My system is:
E6600 OC @ 3.4
4gb DDR2 @ 1066mhz
Nvidia GTX 260 OC @ 725mhz
Windows 7 x64

I can't seem to get Fight night round 3 to be anywhere near playable. I figured my system would be more than able to handle to proccessing requirements. Any ideas of configuration?

GDSX sse3 D3D 10/11 native with allow 8bit

And the problem is? Any screenshots?

The performance is horrible!

I toyed with the configuration yesterday, and I had it flying. But somehow this morning the performance isn't even playable.

Frame rate seems to hover around 60fps but every few seconds I'll get a CPU lag that will completely throw my game off.

But the FPS continues at 60FPS? In that case try turning the speedhacks off, specially VU cycle stealing and EE cycle rate.
