[Wine] 460 GTX performance on SC 2

[defenestrator]

Hello,

I'm trying to play SC2 with the following setup, and it's only playable with the lowest settings.  I think I've already put in most of the tweaks that people typically point to.

Can I get advice on how I can get reasonable fps for higher settings?

Here's my setup:

GTX 460 1GB
Intel Q6600 2.40ghz Quadcore
3gb memory

nvidia 260.19.06
wine 1.3.3

screen resolution: 1920x1200
wine direct3d settings:
DirectDrawRenderer: opengl
Multisampling: disabled
OffscreenRenderingMode: fbo
UseGLSL: disabled
VertexShaderMode: hardware
VideoMemorySize: 1024

Thanks.
