Hello there,
Is there anything like certified drivers for nvidia gpu's? A couple of years ago we had issues with our ati firepros running very slow and buggy. I did some search and found certified drivers by autodesk and it fixed everything. Right now I can work on scenes with around 15million polys without problems and I'm using fairly old hardware.
Look for older or any certified drivers, try swapping the quadro with another gpu like a gaming one. Any chance you could try an older 3ds max version?
cheers
