As per your question, when I delete the preference file, my computer didn't lock up at all.
Granted, I didn't play out an entire game.
But I did play for about 30 minutes or so and the computer responded perfectly.
As for my video ram and the mode I use, I couldn't even guess, but my system is primarily used for graphic design and 3D modeling, so I can't stray too far from that.
I downloaded the soundsprockets and have yet to try it out, but I'm not sure what you mean with regards to the new driver.
Do I need a new one? Will that cause conflictions with my other programs (photoshop)?
Also, is there a preferred color and resolution setting that I should apply before entering the game?
Thanx again
