I blogged last week about converting my new ThinkPad to Vista 64 - well that has been short lived. I lasted about a week before making the decision this weekend to roll it back to Vista 32.
I really thought that if I had to roll back it would be an application that just didn't run. I did my homework on drivers and Lenovo seems to do a pretty good job of having decent 64 bit drivers.
So what was the straw that broke the camels back? Powerpoint! I had a couple of slide decks I had to review and provide feedback on and it was just too darn slow to the point that Powerpoint was completely unusable. All the other Office applications performed reasonably well and would have done just fine. The problem with Powerpoint was it seemed to depend on splwow64.exe which would just hog CPU any time you changed slides or did anything of value in Powerpoint. For example, changing slides was taking 15-25 seconds - I'm just too impatient for that.
I really did though like having my memory report my full 4G of memory being available to the OS and other things ran really well. I think out of this little experiment I have set the baseline for me to give this a try again. To run 64 bit, I will have to have 64 bit Visual Studio and 64 Bit Office Suite.
I'm now back on Vista 32 Ultimate and almost done re-installing all my stuff.
