Material Editor slow as all get out sometimes... anyone else?

[JeffreyMcGrew]

So the Material Editor is taking FOREVER to open a lot of the time.

If I'm in a 3D view in realistic mode, it's much worse. But even opening up a blank drafting view, and closing everything else, it's still way slower to edit materials than it was before.

Anyone else struggling with this? I'd like to solve this one. It's a newish computer, big fat Nvidia GeForce 560 Ti w/latest drivers & a Intel i7. No slouch. However, the graphics card is unsupported for Revit.

If I turn off the graphics acceleration & restart Revit, it returns to normal speed. EDIT: Actually, this doesn't seem to matter. What does matter is if I'm in a view or not and what material I'm picking. Insane!

This is the only issue I'm having, 3D views with Acceleration on are working wonderfully.

So: just me? Anyone else? Anyway to fix this (other than get a card that's supported, which would be slower and more expensive than what I've got right now GOD DAMMIT)?

Hmmm.....I did notice some window rendering issues when I was testing that 580GTX...but I never tried to disable hardware acceleration... if I get the card back will have to try it. But I notice some slowness even now using a Quadro 2000...

Are you sure all file references are correct?

Slow as hell here too. Early stages of a pretty small project. Nothing much going on in there but having the rendering appearance show up takes forever. It eventually gets there but jeez it takes a while.

It's very slow on my desktop but not my laptop (which has a slower processor and less RAM) . Seems like it's looking for files and timing out. One thing, I had previously installed the Beta version of 2012 on the desktop -- I wonder if that has anything to do with it.

[JeffreyMcGrew]

References seem correct. However, some bitmaps are stored on the server. Investigating if that's part of the problem.

It's weird, if I simply switch the Material browser back to the simple materials list & Graphics panels prior to closing it, it works normally. It's when I leave it on the Property Sets list & Appearance that it's really slow in opening it next. Also adding a property set can be very very slow.

FWIW even on supported cards (Quadro FX3800) it seems slow to me on an i7 machine - certainly slower than the previous Materials Editor dialogue.

It's updating the material samples images that seems to take the time.

This worked for me:

Good tip that, many thanks
