It's better to have VSYNC always on, unless you have trouble recording
videos with FRAPS (slowdowns), or have a lower-end comp and too many hi
details cars installed.
According to Zeckensack's documentation,
trying to apply trilinear filtering is useless if the game doesn't
support mipmapping, I don't think that C2 does so Generating Mipmaps
will fix that AND apply trilinear filtering on them.
A negative LOD
bias increases the sharpness of the textures with trilinear filtering,
max is -3, it doesn't have an effect on the framerate, but can cause
shimmering in too low resolutions I think. Need to lock the value, as
C2 might use its internal lod bias if it has any.
Old games like C2 won't kill your comp if you add some 2X or 4X anisotropy :]
It's
useless to load most fancy shaders as C2 doesn't use any, Simple
Shaders are enough and don't make C2O look like a psychedelic progie.
And
for the Thread Policy: I think that choosing Classic is the safest
option, unless someone experiences craches running the glidewrapper
while another opengl program is running.
Ah and refresh rate, I'm not sure that it really works with XP, anyway "by app" is the safest.
