When I use DX 10/11, I get very rubbishy framerates of usually 2-6, compared with ~25 on DX9. The problem is only ingame - the menus give me a 60 FPS. I've tried *someone's* tesselation fix, which has no effect. All FPSs taken from Fraps.

My GPU is good enough for DX10, and the problem is not RAM or anything. (lower when using DX10/11, PC specs are 4-core, 4GB RAM, 2.39GHz, Vista 32.) Turn times are very good compared to what other people are getting - 5-10 seconds even in late-game.

The graphics card is an ATI Radeon HD 2600. It should be higher than min-spec, but I don't know how much higher. Any ideas what's causing the problem?

TIA,

Kid

That's exactly min spec, and it has been observed that Civ5 runs in general very bad under DX10 (-> even if your card was not the issue, then it would probably not run that great).
 
Thanks, DX9 is fine for now, and I'm swapping that card out soon for a dual-screen set up for music production.

Well I've have no actual problems per se, just annoyances, and DX9 is fine for now. As I said, won't be for much longer.
