The official version of the AMD Catalyst 12.1 driver is now available based on the Catalyst 12.1 preview driver released a few weeks ago. Sadly the Catalyst 12.1 driver has no support for the new Radeon HD 7970 GPUs and neither does the new AMD Catalyst 12.2 Preview Driver that was also made available together with the release of the official 12.1 version. For AMD AMD Radeon HD 7900 Series the company recommends users to use the 8.921.2 RC11 driver at least until an official release of the drivers becomes available.
But back to the AMD Catalyst 12.1 driver, as expected from the preview driver released earlier, the new driver adds support for the use of AMD HD3D technology in conjunction with AMD CrossFireX configurations – both for native stereo 3D games using HD3D as well as games relying on the middle-ware partners such as iZ3D and DDD TriDef 3D, as well as well as the new Stereo 3D mode over HDMI 1.4a connections supporting 1080p at 30Hz, but only on compatible displays (anyone tested this already?). Other improvements and fixes in this driver release are oriented at more general things and not at stereoscopic 3D support. As for the Catalyst 12.2 Preview Driver, some improvements to Eyefinity support, but nothing apparently especially targeted at stereoscopic 3D users… maybe in the official 12.2 driver next month we are going to also see support for Radeon HD 7970 as well as other new features such as Eyefinity stereo 3D support with active displays as well as support for 1080p 60Hz 3D mode (anyone know of a 3D-capable display product already supporting this?). So stay tuned for more form AMD and meanwhile do not be in a hurry to pull the trigger for a Radeon HD 7970 if you plan on building a stereoscopic 3D gaming rig.
