Not trying to be needy or take away from the work you are already doing, but can we have an update on what is going on with the crossfire issue?
I'm running
2x ATI 6990's
16 GB of GSKILL Sniper DDR3
Windows 7 x64
AMD Hexacore Black Edition
Obviously you can see my hardware can shred the game, as it sits now I see distant soldiers running in stop frame animation. The FPS lag spikes are terrible. I really want to help test the game ( why I paid ) But as it sits the game for me is unplayable.
Thanks.
EDIT: Have done all workarounds/updates
Ok first of all I will guess that you builded your own rig and that iven if you builded your self you ended up spending a big chunk of money for it....If you had it some inetrnet vendor building it for you,well then thats just plain waste of money and I will thell you why:
1.You dont sport crossfire m8,you are running QUAD fire...(im sure you know that already)
2.You dont gain anything with more than 2 GPU's in games,actually you end up losing FPS and game becomes buggy and problematic,tri-fire,quad-fire......
3.Games have issues with dual cards these days and iven if game gets optimized better by the dev team and the vendor new released drivers and you actually see 80% increase over a single card,do expect to have minimal hiccups from time to time.BC2 for example was a hicup and a half.As for tri-fire or quad fire in your case well m8,your better off shutting down one of your GPU if you want hustle free gaming.....
4.What in earth told you that your CPU or any other hexa or soon to come out hexa/octa from sandy bridge(strongest Intel) can actually push them 2 cards of yours to be fully utilised in gaming??? when comes to gaming the GPU are the legs but the CPU is the blood flow,you got no blood flow,you got no legs to run.I can maeby see 2 years down the road a CPU that can actually push 2 of the 6990's but then I doubt that they will be properly utilized in any games....
5.The only good Tri-fire and quad-fire is good for is a 20-30 min benchmark on furmark or some other stress software....
Sorry to say this but you end up spending lots of money for incoming future headache.You could of been just fine with 2x 6970 or 2x 580's...Iven the strongest I7-2600K OCed to hell cant push these dual single GPU's to its full potential,and yet you bought AMD x6 for quad set up,damn homes....My advice sell one of the 6990 and save your self some money and headaches while you still can,the 6990 are still popular and are short on production....
Im running two AMD Radeon HD 9670 in Crossfire and I dont have any problem. Running with 80-100 fps almost everywhere.
Ok...now go in game,turn on fraps or type the FPS command in the game console,pick up the PPSH,get into fight with someone who is returning back fire and while you aim and shoot that PPSH look how the game becomes sort of laggy or glitchy and then look how your FPS drop to 30-40 FPS...
I get good 80-100 FPS with my 6870's but.......they tend to drop to 30 ish when bugs start to show...after I disabled one of the cards,I get steady 55-60 FPS....with very few bugs.
