Crossfire performance not up to par?
So I'll jump right into it: I'm well aware that Crossfire doesn't actually double the performance (at least not in every game) but the performance I've been getting in some games doesn't seen to be at all acceptable. I ran the in-game benchmarks for F1 2011 and DiRT 3 both with crossfire disabled and enabled, details as high as they can possibly go, and here are the results:
CrossfireX Disabled - DCII clocked at 810/1250MHz
F1 2011 - Avg. 51 / Min. 45
DiRT 3 - Avg. 56 / Min. 47
DCII Clocked at 850/1350MHz
F1 2011 - Avg. 52 / Min. 47
DiRT 3 - Avg. 58 / Min. 48
For the next round it's enabled and both cores will now be running at 820/1250MHz as the Sapphire card runs 10MHz faster than the DCII at stock; both games running under their respective profiles, and as DiRT 3 seems to have a handful of them I used the dirt3*.exe profile.
CrossfireX Enabled - clocked at 820/1250MHz
F1 2011 - Avg. 73 / Min. 61
DiRT 3 - Avg. 104 / Min. 90
Clocked at 850/1350MHz
F1 2011 - Avg. 73 / Min. 61
DiRT 3 - Avg. 108/ Min. 92
F1 2011 annoys me the most because the performance gain isn't even as much as the gain seen in DiRT 3 which more or less does in fact double over using one 6950. Both games use the same engine but it seems DiRT 3 is a bit more optimized as far as the engine goes. I've more games on hand, most of which aren't installed but I'm wondering if this is at all normal.
I don't remember my performance with a single card in Crysis 2, but with Crossfire I'm seeing anywhere from 80-100+, and this is with mods.
