Some odd stuff here. I installed Cat 11.5 as per the hotpatch instructions, even uninstalled and redownloaded a fresh game install from steam - all fine. Quick play about in the game, everything as it was, no problems. Go to CCC to enable Xfire to see if it works... and it's already on!
Default of course after a new driver install (I forgot all about that), but wow, crossfire worked! Went back in, tried a level - almost smooth, nearly all the stutter gone. Brilliant! Remarked to my mate about over steam as he was testing the patch too.. loaded another level...
bang, massive performance drop. After some testing, it seems that the first quick level I load post patch with xfire enabled gets decent xfire performance (stable 30-45, almost no stutter, prefs a notch or two higher than normal). The next, and any subsequent levels I load then revert to the traditional crossfire result: fps spiking from 5-20 average, massive stutters and loading pauses etc. Quit out of the game completely, reload and the first level will get good performance again - until I load another level, when it all goes bad.
Anyone had similar?
Also new prop is nice! Thanks team.
