Yes, I shudder at the thought also, but i noticed something today when playing with the 'graphicsconfig' in autocad 2011...
now, obviously they dont make a GTX 460 with 4gb of ram. i have the 1GB version. is there a way that autocad is using shared memory for their driver (since i dont have a special quadro driver)?
in the same regard, could this be happening in revit also?
since we only really have 2 3D options in revit
"use hardware acceleration"
"use anti-aliasing for 3D views"
i only bring this up as i was testing the newer beta geforce drivers. I noticed the using gpu-z to show the gpu load, it never really got about 5% regardless of if i had 3D enabled in autocad or revit. I also noticed that whether i had 3d enabled or disabled in autocad or revit 2011, my cpu usage would max out at about 15%.
we share our office space with an civil firm, they have civil 3D. gpu usage (autocad 3d enabled) maxes out @ 30%, and stays in the 0-5% range with it disabled (assuming 5% is just windows aero, even though we both have them configured as windows basic to reduce on system overhead)
specs:
i7 870
8gb ddr3 1600
geforce gtx 460, currently 270.51 beta driver (previously 267.91, 267.24 beta, 266.58, and 260.99)
win7 x64
