|Those of you that has been using a NVIDIA card with
Maya has surely experienced the terrible slowdown problems..
They are usually triggered when you go into the PaintEffects view and paint something, when you go back to perspective view, the slowdown has appeared. And even if you delete all strokes etc. it is still there!
If you switch back to the painteffects window chances are that this
will run very well...
Using the viewport resizing with the center '+' of the 4view, I tried
to make the different viewports bigger.
Why??? I assume it has something to do with memory transfer to-and-from main memory? The reason why PFX triggers it I assume to be because it uses a lot of mem to all of its planes?
In any case I think, based on these observations, it ought to
be possible to construct drivers that does not slowdowns..
I have tried with a lot of the beta Detonator drivers off http://www.3dchipset.com/ these are usually very good, and something like 7.58 runs _much_ better than the 'certified' 6.50, I have also tried 10.80 and 11.01, I have not made any speedtests, but they seem to run very well aswell.
This test was performed using the Detonator 10.80 on Win2k on a geforce 256
preliminary tests suggests that Detonator 11.01 on Win2k handles all above situations without slowdowns!!!
