Hi, I was also wondering is there some way of getting this Directx 10.1 for Win7-64 and will it be beneficial to games othere than AC.
Im not sure if it was down to this or my card getting old but I used to get 7.6 in the win7 benchmark test now I only get 7.3 no matter what I try. May be someone could shed some light on that coz ive lost performance in games over this. Games like gta iv have become unplayable and Im oblivious to the reason why. Ive tryed reinstalling my comp with lots of difrent typs of hd setups and win7 home/ult but nothing makes my card run like it used to.
one thing you could check is the temp's on your video card and CPU, a similar thing happend to me, used to be able to run just about anything without an issue, like Crysis with settings on the 'medium-high' end, but after a while (months) i was unable to get even playable frame rates on anything, even with all settings on minimum.
Then one day i had to open my comp case to swap out of a dvd drive and noticed that my heatsinks were completely clogged with dust and crap. (temps were still in 'acceptable' levels, but still pretty hot) so i completely cleaned it out and installed a new high performance CPU cooler and added a couple case fans, and problem solved.
amazing what a few Degrees in temperature change can do with a computer, and im glad i caught it before it really caused some damage.
hope this helps with your problem.
