even though i have an archaic nvidia 6200 in my links machine, i'm still a big fan of tweakforce modified drivers:

i've been using the xtreme-g 181.00 xp for quite awhile, with no problems. earlier, i tried the 185.20 xp. everything looked fine until after i took my shot. all of a sudden, the display would go into slow motion. i tried several tweaks to no avail. i just reinstalled the 181.00 xp, and links works great again.
