FPS problems on DX10

[KidJustKid]

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

The graphics card is an ATI Radeon HD 2600. It should be higher than min-spec, but I don't know how much higher.

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.

Minimum specs = can get to the main menu. Thats basically what they mean most of the time.

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.
