Code:
- Added support for the following GPUs: GeForce GT 705 GeForce GT 720 GeForce GTX 860M GeForce GTX 870M GeForce GTX 880M GeForce GTX TITAN Black - Fixed a bug that could lead to crashes when running Left 4 Dead 2 with threaded optimizations enabled. - Updated the makefile for the NVIDIA kernel module to work around a bug in older versions of GNU Make that prevented the NVIDIA kernel module from building correctly.
