2900xt Coh Benchmark bug?

[Clock.It]

Hi,
just wondering if anyone has noticed this and is it a benchmark bug.

When i first ran COH (the unpatched version) in 1360x768 all settings/sliders maxed (4AA) i was getting a minimum framerate of 47/ average 100/ max 180 approx. in the ingame benchmark.

Then i patched to 1.40 and the minimum framerate went down to sometimes 14, sometimes 27, but the average and maximum stayed the same.

Patched to 1.70 and the same result but i noticed while running fraps along with the ingame benchmark the minimum framerate never goes below the original 47 that i got on the unpatched version.

On the odd occasion it does display the correct value.

Is this a vista, benchmark or system bug?

COH with the 1.70 patch is abysmall. Just applying the patch dropped my framerates in the built in benchie by half. Went from a max of nearly 200 down to 97fps. The minimum has dropped to 14.7. It's a joke. So it's not just a 2900 thing.

It seems to be a benchmark bug with the minimum framerate on my system as the maximum/average framerate stay the same on patched/unpatched version and fraps reports a minimum framerate of 47 while the benchmark says 27.

Have you got dx10 enabled? That would account for the fall in performance.
