Revit 7 - Graphic Cards/ Configurations that do NOT work

[Wes Macaulay]

Same rules as last year: if video performance is poor when...

OpenGL acceleration is enabled in Revit
and/or

Windows hardware accleration is set to maximum
...then your setup is considered to not work.

(Given that overlay planes don't seem to help any of the cards I'm on, I've ignored that setting here as contributing to whether your video card "works" for Revit or not. Mods... do change this if needed!)

Win2000 SP4
OpenGL slows refresh times; overlay planes make it worse.
Windows HWACC > full, with OpenGL acceleration off video performance is comparable to 6.1 where OpenGL WAS turned on.

Windows XP SP2
nVidia Go FX5200 video card w 64Mb RAM

Driver versions A07 and A08 drop lines with OpenGL on and overlay planes off. Driver version A06 works fine.

Sometimes NOT using the latest version may be the trick to getting the most out of your video performance. I don't understand why some driver versions work and some don't...

We're way back on NVIDIA GeForce4 MX440 with 64mb and they are DEFINITELY NOT working for us...lots of ghosting issues with Revit 7--I'm getting elusive dancing lines constantly now.

Those cards aren't too bad. You need to find out who made those cards - take apart the computer if need be and find whatever you can on the video card to identify it. Or call the company who built the computers for you (is this one of those Compaqs you folks had down there?)... get the information from them.

nVidia cards can be next to useless unless you have the right driver.

It's one of the Sonys, and it's just about 2 years old. Seems, from my understanding, that we can't upgrade the video card because the mother board only recognizes the "old kind" (graphics cards are something I don't know much about).
We had open GL on for a while and then my computer freaked out this morning so we had to turn it back off. We are currently looking into some options and definitely the driver is one of them.
It was working fine for Revit 6 but when we upgraded to 7.0 we've noticed issues on both the sonys and the compaqs. Most of the issues I have had involve using an autocad underlay and then zooming way in on it to trace, that's when the lines start dancing.

Check on Sony's website to see if they have a driver for that computer... typically big mfr's of computers generate their own drivers for their own computers; but you should be able to look inside the computer to see if the video card is labelled or is otherwise identifiable. The basic nVidia drivers that Microsoft provides really don't work at all, with Revit or AutoCAD.

I looked at the Sony website and it appears that most desktop models do have Sony-provided drivers - I would recommend downloading the one for your model and installing it.
