About the ATI/Win 7 64 known bug. The problem there is, I have windows XP media edition, and an Nvidia 9600 GT graphic card. Edit: I also have the memory leak, but since I can't alt-tab much, I can't find out what increases memory usage easily either. (I'll try the maximize window thing next.).
@Stardock: PM me and I'll happily help with doing whatever is needed to help identify the problem.
@Rune_74: Yes, I agree completely. The game flows much better, although I did have to go sleep for a while. Now I'm back and going to log a lot more hours on this. 
Changes:
The biggest change is in many of the small details. Character creation has less oddities, more icons (for talents/weaknesses, for instance), the nations include information on what race they are (The Yithril are just 'Fallen', but the rest are a specific race.). The Yithril no longer start with an exceptional longbow, but they start with piercing weapons researched, so you can create archers from the start. BIG advantage as far as I can tell.
Interface has a few more subscreens, the Hiergamon infromation windows has more consistent links and descriptions - better organized, tabs for the spellbooks, etcetera.
One surprise - casting spells is no longer an action you can do; you need to click on 'abilities' tab and 'channeler' to cast spells. A little unintuitive, but it's still on the character, at least.
About tactical combat, bows no longer shoot at 45 degrees to the right or left of the target and still hits. Jay. 
Unfortunately scrolling with ASDW or edge scrolling is not enabled, you need to zoom out and then in to do anything at range. That's a bit clunky.
I did get an all-white tactical screen (landscape and units, not interface), which was a Beta 4 bug as well. I think it's connected with the out of memory thing, but not sure. I did take a screen shot but not sure how to put them here.
More huts, more quests, more lairs, more STUFF.
