I have a Quadro FX 3700 and want to know if Maya supports Quadro SLI.
Well it draws polygons faster yes (tough i dont have one i just observed one once, but please read on to understand what your up against). But no extra support for sli is there no. But thanagin thats how sli is supposed to work, no extra support needed.
Im supprised your ganimg rig does not speed thinsg up since atleast my maya works faster even on the 9800 GTX SLI settings when tested. However read on its really hard to measure.
However please note:
drawing speed is seldom a a maya users bottleneck, as all of the dg is done by the processor. So yes its really hard to get out a scene that actually seems at firts glance faster on a dual setup. Since having a character move about on screen does in general NOT GET ANY faster just because you hit two gfx cards on the machine.
So assuming a rig that runs at 12 fps would go double that is a fairytale, its still going to be 12 fps. Since the likelyhood that of those 12 fps the botleneck being the gfx card is allmost 0!
So whet this means that the only way you can see a speed increase is by actually having a lot of things on screen where the polygon/pixel fill draw is the limitting factor. Thsi is hard to achieve. But you can do this if you switch hi quality drawing on and have a lot of cg shaders.
Second problem si that the bandwidth of your transfer inst any faster as its absloutely as slow as it ever was, so deforming things diont get much faster.
But at the end of the day the difference will not be worth it. Unless you have a studio with a lot of internal dev and multipas ogl renders inside maya.
So to test this again:
amke sure you have a scene that on simple scelne with minimal deformation, history anim,and a LOT of textures in high quality mode. Then make sure your gfx cards v sync is off, because this will act as a limitior. Then set the plaback to all frames. then chek out the results. Ona long looping anim.
So at teh end of the day you cant just slap more hardware without knowing where your problem is.
So instad if you need more on screeen feedback power make sure you have the fastest processor on the market, then if rendering speed multiply cores. If you need some fancy custom preview feedback thats running on a lot of cutom code get a second card. That gives touy the base guidelines.
