Been using the beta drivers for a while now, and with those beta drivers I’ve noticed great improvement in framerate and overall performance. Considering that these final drivers don’t appear to change much, performance is largely the same, but its still much better than with the previous stable drivers.
Running a GeForce 560 Ti. Also note that I’m running on Windows 8 of course, and I’ve been getting better performance ever since switching to Windows 8, so that may help as well.
