This is the exact same issue I was having. Not on my G73 [though I have one] but on my DESKTOP.
It acts very similarly to an overheat, some kind of grahpical distortion, freeze, then a solid screen and [in my case] an error message. For me, turning AA down to 4x from 8x and disabling depth of field got rid of it.
I'm thinking it's some kind of memory hole, though I'm by no means a programmer. Rest assured it is a software issue, not a hardware one.
No, it's not overheating, i checked with my Hardware monitor and i run the GPU at 56C and mainboard at 48C.
what kind of miracle G73 do *YOU* have??? Mine *IDLES* at 56c. Runs the game about 90-93c Edited, Sep 6th 2010 7:35pm by seneleron
