Hey guys,
been trying to follow guides and advice on getting to max the frames to 60 and still seem to be struggling. This is including max AA as well but still can't accomplish. I'm only getting 35-40 and sometimes with larger areas it can spike with the rendering. I'm only really interested in the single player mode as well if that takes into account. This is also just running single screen @ 1920 x 1080

I'm running:
- 3 x 7950 tri-fire configuration (reference gigabytes) - both which are o'cd to 1100/1400mhz and cooled
- i7-950 clocked to 4.0ghz
- 20gb of Dominator-GT 2333mhZ
- X58-UD3r gigabyte mobo
- 950w Antec PSU (not sure if this becomes relevant but it doesnt appear to be overloading/underpowering)

most of these devices have dedicated air or LCS hybrid systems, so temps never exceed 50 on GPU and CPU etc.

I constantly see driver support issues and cross/tri scaling to be poor but cmon, really? this bad..? Also, there is minimal boost between 2 cards to 3 cards. I'm not sure if this is game is that GPU intensive or if the PCI-slots have something to contribute..I JUST NEED AN EXPLANATION!

theres a new beta released yestarday which is supposed to help in crossfire configurations.

I think I heard somewhere that SLI/Crossfire setups have problems with C3

Try with a single card.

It also seems people with high end cards are having serious performance issues while mid range cards perform fine. Try avoiding SP levels which have ropes because apparently, they have been "extra" tessalated and are full of steroids almost cutting your FPS in half (this is a bug and not intented)
