The 3d wheels in the jfCarSet add about 240 polygons per car, so they will
slow things down a real lot, enough that I don't use 3d wheels. Also your
MX may be slowing things down (that's a total guess). If you need better
fps you'll have to turn the detail bar down in GPL.
Anyway, I have these settings in my core.ini -
[ Int Profile Values ]
value3 = Direct3D7:D3DDevice:0
value4 = Direct3D7:TossHighestMip:0
value5 = Direct3D7:TrilinearFiltering:0
value6 = Direct3D7:DoubleMirrorResWidth:0
value7 = Direct3D7:DoubleMirrorResHeight:0
value8 = Direct3D7:DirectMirrorRendering:0
value9 = Direct3D7:DisableZBuffer:0
[ Direct3D7 ]
D3DDevice = 1
TossHighestMip = 0
TrilinearFiltering = 1
DoubleMirrorResWidth = 1
DoubleMirrorResHeight = 1
DirectMirrorRendering = 1
DisableZBuffer = 0
