received a PC patch this weekend, with fixes for the Nvidia-associated stability issues high on the agenda. The patch notes mention corrections for "some stability and startup issues on machines that have both Intel and Nvidia graphics hardware" and "some small improvements to TressFX hair rendering." These chief issues led to Nvidia apologizing
for the game's unstable performance at maximum settings on its GeForce cards.
Going by the Steam
forums, the patch does provide significant improvement for some of the stability issues, although by the sounds of it TressFX is still somewhat flaky.
