Game lagging with my hardware on low details

[Belhade]

I decided to flush my .ini last night. Removed my UserOptions.ini and started game. Default graphics were almost all set to High. My game ran almost perfectly. No lag, no clipping, no warping, no stuttering. I was getting a solid 20-25 FPS in battle (which for me is good, as long as it's stable) - this includes an armor column, then mass infantry battle at Camp Collins. I've never seen this game look so good - and it was a nighttime battle, too! Previously I'd set everything to Low options, or turned off, since my system is on the lower end of the specs - but turning it all back on and cranked up worked great. We're talking a Phenom II x4, nVidia 460GTX 76mb, and 4GB RAM. And Win7 64-bit.
