So I just got a new laptop (Lenovo Thinkpad T400). It's obviously not a hardcore gaming machine, but it's vitals are respectable: Intel Core 2 Duo P8600 (2.4GHz) 4.00GB DDR3-1066 RAM (2 from Lenovo, 2 installed by me) ATI Mobility Radeon HD 3470 (256MB) Vista Business x64 Ran 3dMark06 and got a score of ~2500. There are a few games I'd like to be able to play. One of them is Civilization IV: Beyond the Sword. However, when I run it (albeit at max settings, 1440x900) I get fairly poor performance. Like low 20s FPS. For comparison, I can play Fallout 3 at 1440x900 with High texture setting (all others minimized except for draw distances at about middle) with similar frame rates. Any ideas what the deal is? And why Beyond the Sword keeps triggering the UAC popup whenever I run it? Thanks. PS I couldn't tell where to put this, so my apologies if it's in the wrong place (sorry!). It's not really a BTS bug, but definitely does concern BTS. EDIT: To add to the weirdness, when I'm interacting with another leader, the FPS jumps back up to 50 (same as it is in the opening menu).
