Yet more Crossfire woes

[Cyanide]

Yesterday I tried out these ATI Drivers and they killed my Crossfire setup - it was running like a pig and I lost around 10fpd in Crysis. This morning I uninstalled them, used a driver cleaner then went back to the latest drivers from the ATI site. Still got naff fps in Crysis.

I tried taking out the second card and running without it and it was fine, was getting around 35fps in the Crysis benchmark. I then proceeded to pop the second card back in and re-installed Catalyst so it'd recognise it. Down to 29fps and CCC doesn't seem to realise the second card is there. It's given me the option to enable Crossfire, which I have, but it's only showing one card in all the options (Overdrive etc).

GPUz only ever shows one card but Everest, which usually works fine, isn't reading either for some reason.

I'm pretty much certain it's a driver issue but I haven't got a clue how to fix it, anyone got any ideas?

What was your performance like before you tried out those ATI drivers?

I was getting around 38fps on the Crysis Benchmark (my cpu's limiting the Crossfire)

Have you done system restore to see if you can get back your previous driver state?

'Not the go to previous driver' option on the device manager but the backup and restore part of windows.

I tried those drivers as well, and decided they were a bit rubbish, so went back to the standard 8.1s. Haven't run any games since but 3DMark gave me 18200, so I'm guessing everything is set up OK again.
