Sidestepping the quadro vs geforce debate for the moment.
Is there anyone here running an nvidia geforce 8800 gtx with Houdini 8.2
in an windows environment? Or heck any other environemnt. I'm starting
to crack the iceberg in testing, and I know that with this relatively
new card and gpu architecture, there will be some driver issues. Maya
users have been complaining about the 8800 gtx for redraw so I suspect
the problems I'm having are purely driver related. I suspected 64bit
windows may be causing the problem but I'm hearing these redraw issues
with win32 as well.
I'm currently running forceware 158.22 on Windows XP Pro x64 driving
twin 1920x1280 displays.
With this driver set, the redraw gets corrupted really easy when I have
nView enabled [two independant displays]. After awhile, channel boxes
will fill with garbage characters. Within a few minutes I'll get a BSOD.
If I turn off nView and have the drivers treat the two displays as one
large 3840x1280 desktop, houdini is very stable, and fast. There are GUI
Clipping and some minor redraw issues but nothing show stopping.
I'll have to do more testing including:
- turning off the opengl/hardware accelleration via the environment
variable to confirm its a driver issue.
- running older drivers and beta drivers
- running rivatuner to softmod the 8800 into a quadro 4600
- installing ubuntu and see how the situation is on the linux side.
Worse case I can return the 8800 gtx and get a quadro fx 1500 or 45/4600
or just sit with the card and wait for driver improvements.
If anyone has gotten things working nicely, what version of driver are
