We have been running SW 64 bit for about a year on one seat, running XP Pro x64 SP1, Starting with SW06 and then upgrading to SW07 SP3.0
SW06 seemed slow when first installed, but the O7 version seems better in this respect and loads itself and files about 25% faster than our 32 bit seat.
I had a lot of crashes at at first with 07 and these seemed to be graphics card related. For example, when switching between two loaded assemblies (each about 3Mb and less than 100 components), the Title Bar and Tree pane would change, but not the main window which remaind showing the first assembly. Moving the mouse over the Tree would cause pink lines to appear over this assembly, showing the outlines of parts of the model it should be displaying. Closing this model would leave the desktop showing in the main display pane, Sometimes re loading the model would recover the display but it would be unstable and lock up big time or SW would just exit.
Similar to Simon, I have an ATI FireGL Card, a V7100. I was using the SW certified driver 8.163.1. Switching to Software OpenGL cured the problem and indicated driver problems. My VAR suggested uninstalling all card drivers before reinstalling the certified driver, but this did no good at all. I then tried the driver cleaning tool i found recomended on this forum, before reinstalling, but it still didn't work. Finally, I downloaded the latest uncertified ATI driver for the card 8.323.0.0 (6/12/2006)from the ATI site and this has worked very well. Testing it (and deliberately pushing my luck), I have had as many as seven assemblies (including our biggest), several parts and a couple of drawings all open at once, I can switch between these with no troubles and even open an eDrawings viewer and load a large assembly at the same time.
However, I have found a method of killing it. Open the eDrawing viewer FIRST with a model over about 3.5Mb in size and SW will load with a hole to the desktop where the Main display pane should be and the system locks solid. Smaller than 3.5Mb, or opened AFTER SW, then all is fine.
One related anomaly that I have reported to my VAR, but they have not yet come back with an explanation, is that whilst Windows Device Manager correctly reports the installed ATI Driver Version and date, the RX Diagnostic report always shows an incorrect driver and date, so I guess it's looking in the wrong place!
Simon, I too find that DrawCompare is always running and I hadn't noticed it before!
Also on the 64 bit seat, but that may not be relevant, I have had a few spontaneous changes of Toolbox Fastener sizes when converting to 07 from 06. The assemblies involved have previously succesfully migrated through 04 and 05 without problems. SW and my VAR have not been able to find the cause of this and I wonder if anyone else has had similar experiences?
