Reinstalled the entire game and validated. Started a new game.
Biggest problem I had was only mentioned once (by Barak on p.6)
Cities. Click on one, and it will show you the city that was previously clicked. So I have to Return to game then click the city I want to look at again to see it.
Switching focus takes 5-10 seconds to update the screen; previously it was near instantaneous.
City View cycler does not work at all.
A number of times, "Choose Production" was the only option available to me. After production was chosen, the button would not change. I would need to change to Wealth (no unit or building would work, Research might), wait 5-10 secs for it to change and then it would give me the "next turn" button. Changing to the production I wanted worked fine after that. At least until next turn. Queuing production in every city might fix this, I suppose.
Also Unit Cycler was very buggy.
Improvement - The game Never lags (as in processing for a few seconds seemingly randomly) This is quite possibly related to the bugs above. If it's a choice, the old way was better; at least you wouldnt misdirect your units with fatal consequences.
Turn processing times seem no different.
RE: RETIRE
So you can see the graphs and whatnot, to analyze your loss without playing it all the way to the bitter end. That's the point of it; not HoF. And it's pretty cool.
Processor Pentium(R) Dual-Core CPU E5800 @ 3.20GHz, 3GB available RAM
Video Card Intel G45/G43 Express Chipset.
Video settings were at lowest available before, and did not change.
I haven't really tried it with higher settings because of Teh Pheer.
