Dimensions drag speed in Revit 2010

[jzee.101345]

I have just had some time playng with new release of Revit X64.
Along with some perfomance gain comparing to 2009 X86 version I've discovered some slowdown during dimension manipulations. When I'm trying to move dimension value digits they switch to the not antialiased mode then moved to a new position and became antialiased again as I click the mouse. While in 2009 version digits always stay antialised during manipulations and perform it more smoothly. It doesnt depend on font type used, but it seems to me that speed depends on the number of values dimension chain contains.
Can somebody confirm the same behavior or is it just my issue?

Might be a graphics card thing?

Can't say I've noticed any difference in dimensions so far in Revit 2010_64

i havent tried it in 2010 yet, but if i had a dimension string in 2009 that was more than 50 entries/dimensions along the string, it would lag terribly. but if i did the same thing with 5-6 dimension strings for the same entries in the same location and select them at the same time and drag them together, there is no lag. so typically i would do that rather than having a super-mega dimension string, i would have a couple that do the same thing; especially with the 2009 jumping dimension locations when you would add or remove a dimension and some of the dimensions on the string are not in their default location on the string.

Confirmed - my dimensions do it as well from time to time. Using RAC 2009 X64 on Vista Ultimate X64 with ASUS EAH4850 512MB DDR3.
