I have noticed some improvements, but it depends on the graphics card, of course. We had been investing in Nvidia Quadro cards, which are great for heavy OpenGL work, but perhaps only so-so with DirectX (at least at the level of card we've been buying). With Revit 2010, a really good consumer level card seems to work better for a lot less money. Given Microsoft's move away from OpenGL, this seems like a good move for Revit.

Does the new caching scheme reduce a workshared model's network chattiness? One thing we're dieing for is WAN performance improvements.

No the caching I mentioned is related to Graphics and not Network performance.

Tsvetan -- I and many others appreciate the efforts you're making with graphics performance that we're putting up with the confusion & delay caused by the new UI.

We noticed an immediate improvement in display performance in 2010, which goes a long way to address the regression in performance between 2008 and 2009. We have a mix of Quadro, Geforce, FireGL and Radeon-based computers and all of them are seeing similar results on XP32 and Vista: faster than 2009, a tad slower than OpenGL in 2008.

As important as generation of a new view is, most users would likely tell you that navigation speed in 2D and 3D views is the most important metric of all. Frame rate is very important so that when you are spinning in 3D or panning in 2D you can quickly start and stop and not lose track of where you are, or be held back by the software.

We look forward to future improvements in this regard!

I've noticed a small increase in view performance in certain views, which is great, but this is offset by the poor graphical performance of the Ribbon UI.

The Ribbon in my experience is quite slow and sluggish, and a lot of the time I am able to think far enough ahead and place my cursor over a tool quicker than the Ribbon can regenerate. This is on my work PC. On my home PC, the regeneration delays are 4 times longer.

I'm hoping that The Factory is providing plenty of resources to improve the graphical performance in this area, to make the Ribbon perform far quicker than it currently is.

Thanks Tsvetan.

It's interesting that you mentioned the current system still supports OpenGL. Why is there only an option to enable DirectX hardware acceleration then?

I've noticed a considerable performance improvement migrating from 2009 to 2010. Keep up the good work.

David, Hardware accel is only enabled in DirectX because we had to focus our efforts on getting that right in this release.

Very interesting, thank you.

Is there any hope of there ever being certified graphic drivers for Revit?

All my other cad applications have them, it has always baffled me that Revit does not.

There will likely be little need for certified drivers because of WHGL, Microsoft's own test for drivers under DirectX...

Erik and others, see this poll:

I think this change should be put into Revit in the next Service Pack.

NOT A SINGLE PERSON WOULD COMPLAIN ABOUT THIS CHANGE -- THEY'D LIKELY DANCE FOR JOY ABOUT IT!

I have not noticed any speed improvements with Revit 2010, in fact, 3D views with shadows are slower to regenerate than with 2009.

We are using Quadro FX370M with 256Mb graphics memory and Quadro FX1500 with 256Mb graphics memory. Both with the latest drivers. Niether card is any faster than the other, and both are slower than 2009.

Are there recommended or certified drivers for graphics cards, in the same way as AutoCAD?

At this time, Autodesk does not certify or even recommend specific graphics cards for Revit. There are a few posts over at AUGI (including this one http://tinyurl.com/o2y9cg) where people are discussing hardware setups that work well, and those that do not.

Is the difference in the temporary dimension display a part of the DirectX update? 2010's are fuzzy and hard to read.
