Also there seems to be Intel drivers merged together with the ATi drivers.
What's up with that?
No idea. Maybe to be sure your chipset is up-to-date as possible when loading the newer drivers - there's even raid drivers in there - looks like motherboard updates. AMD chipset drivers are there too. Direct 3d version of these is 750, while the next newest I could find are 735 in the 10.3b betas. Terry 'CatalystMaker' Makedon is tweeting that he doesn't know where these came from and 'he would never load them himself'. Sounds fishy. :0 Ie don't expect any support since this is in no way official, pre-release, beta, alpha or anything else. It's just ripped off the driver team's computers. These drivers are so much further down the line and they are leaked internally. There's even some people joining the guru3d thread saying that they are fake. (Which is funny because they are doing a great job really running real games on real hardware on my machine ;p).
They're very green and are intended to be the 'WOW' drivers for after Fermi release according to a poster at Guru3D. Another obvious sign supporting the 'stolen / leaked' theory is that this one rar includes everything the driver team works on. MCE Drivers, Crossfire profiles, APP profiles, .net, Visual C++ run-times, Online Registration, Communication opt-in, ATI problem report wizard, Hydravision, Opencl, opengl, d3d, avivo, CCC, WMD, HDMI, WMV decoder, install manager, and everything in between all the way down to the video encoder integrated into CCC. It even has smartgart for AGP... They are the most complete set i've ever seen; however you might find parts of it to be useless bloatware, and there could be tons of bugs yet to be ironed out. It's a bit overkill IMO, I always go for the minimal installation. You can still manually install only the display driver if you wish and keep older CCC versions, or even no CCC at all. This definitely isn't for the newbie who will likely install over his old set, BSOD, and need to call tech support to figure out how to boot back to windows. Someone else posted gains in BC2 from 55 fps to 75 fps, but I haven't noticed anything that big. In BC2 my 4890 is only slightly smoother on these than the 10.3b march 29 drivers, and there is still flickering in some of the grass textures.
