NVIDIA Optimus BSOD

If you own an Alienware m11xR2 like Eileen, and are playing Torchlight II with frequent blue screen of deaths after around 20 to 40 minutes of game time, there is a fix for this. According to the pooled sources that I have found, this is related to the shader clocks being on the high side. A working solution is to download MSI Afterburner, enable the ``Legacy GUI'', and shift the clock speed of the shader down by around 50MHz. I usually run this tool after launching Torchlight II to ensure that I am indeed running on the NVIDIA GT 335m graphics card as opposed to the integrated one.

After quitting the game, I always reset the clock rates. No harm doing that, really.
