NVIDIA has been pushing for WHQL certification for their drivers, but sometimes issues slip through QA, both at Microsoft and their own, internal team(s). Sometimes these issues will be fixed in a future release, but sometimes they push out a “HotFix” driver immediately. This is often great for people who experience the problems, but they should not be installed otherwise.
In this case, GeForce Hotfix driver 361.60 fixes two issues. One is listed as “install & clocking related issues,” which refers to the GPU memory clock. According to Manuel Guzman of NVIDIA, some games and software was not causing the driver to fully wake the memory clock to a high-performance state. The other issue is “Crashes in Photoshop & Illustrator,” which fixes blue screen issues in both software, and possibly other programs that use the GPU in similar ways. I've never seen GeForce Driver 361.43 cause a BSOD in Photoshop, but I am a few versions behind with CS5.5.
Download links are available at NVIDIA Support, but unaffected users should just wait for an official driver in case the patch causes other issues, due to its minimal QA.
