[osg-users] Lagging while 3D maneuvering

[L. Voerman]

Hi Knut,
after basic checks (os - driver version - driver settings) I guess I would
try to make "identical" screenshots on the problematic machine and a normal
machine,
and get photoshop to subtract the results.
This could point out differences in:
stereo - quadro cards can do stereo and might only show one eye.
anti aliasing - quadro's can do more (lines for example) - this might cause
a performance hit
anisotropic filtering - different defaults?

Further options:
driver setting for "Threaded optimization" - not sure what the "best"
setting is - but I think it changed performance for me once.

Laurens.
