"Display driver stopped responding and has recovered"

[TonyS]

I already tried that. Just tried again and I triple checked that I hadn't missed anything out and that the value was set (http://i.imgur.com/JzwA68U.png), but it's still happening.

Roughly a minute and a half into the attack, the PC totally froze and I had to do a hard reboot. It worked totally fine up until then though.

This was with these drivers.
