Guild Wars 2

In 90% times my video driver crakitten snow storm stages in this fractal. I have GTX 660ti video with latest drivers. What should I do? Or is it a bug?

Check the temperature of the computer while you are doing that fractal stage. It may be overheated and that could cause it to crash

75 C max. I use many benchmarks, but no one caused my driver to crash. This happens only in Snowblind fractal.
