Anyone with problems with ATI drivers read this.

Dan,

We are running similar systems. (AMD64 955BE, 4Gb RAM, Ati 4890, Win 7 here).
Here is the OpenGL section from my conf.ini :

[Render_OpenGL]
TexQual=3
TexMipFilter=3
TexCompress=0
TexFlags.UseDither=0
TexFlags.UseAlpha=0
TexFlags.UseIndex=0
TexFlags.PolygonStipple=0
TexFlags.UseClampedSprites=0
TexFlags.DrawLandByTriangles=0
TexFlags.UseVertexArrays=0
TexFlags.DisableAPIExtensions=0
TexFlags.ARBMultitextureExt=1
TexFlags.TexEnvCombineExt=1
TexFlags.SecondaryColorExt=1
TexFlags.VertexArrayExt=0
TexFlags.ClipHintExt=0
TexFlags.UsePaletteExt=0
TexFlags.TexAnisotropicExt=1
TexFlags.TexCompressARBExt=1

TexFlags.TexEnvCombine4NV=0
TexFlags.TexEnvCombineDot3=1
TexFlags.DepthClampNV=0
TexFlags.SeparateSpecular=1
TexFlags.TextureShaderNV=0

HardwareShaders=1

Shadows=2
Specular=2
SpecularLight=2
DiffuseLight=2
DynamicalLights=1
MeshDetail=2
VisibilityDistance=3

Sky=2
Forest=2
LandShading=3
LandDetails=2

LandGeom=3
TexLarge=1
TexLandQual=3
TexLandLarge=1

VideoSetupId=17
Water=2
Effects=1
ForceShaders1x=0

PolygonOffsetFactor=-0.0625
PolygonOffsetUnits=-1.0

In the Catalyst setup I use the following settings:

Anti-aliasing enabled, level=4x. Filter is Wide tent, samples=8x

Anisotropic is enabled @ 4x

Catalyst AI is Disabled

Mipmap Detail level at High Quality

Vertical refresh is On

Adaptive Anti-aliasing is enabled @ Quality

Triple Buffering is Enabled.......................

The last setting relates to Vertical Refresh which I use to prevent 'tearing' of the cockpit bars when I look around using TIR. If you don't use VR then switch Triple buffering Off.

Have a try with the stuff above. I get very good results with good eye-candy and useable framerates.
