Hesitant to ask and start another complaint post, but here goes (Seems we are all walking around on pins and needles this week!). I would like to update to 1.8 A of B or whatever is available. Trouble is I have an older PC and I am not building my next one until next summer when Vista has a patch or two behind it. I'm on version 1.61 which was a godsend, and smoothed out all the version 1.5 performance issues (just like frogboy promised) for my current Athalon 1700 and NVidia 6600GT (factory OC) with 1.5 gigs of memory. I stick to Large maps and occasional stars/habitable, and can't wait to go bigger but am resigned to now. So what I really want to know is whether all those wonderful changes listed in the 1.8 changelog will impact my current very satisfactory game performance. Anyone?
