I like to add from yesterday, that I noticed my system was affected by this beta. It seem to have broken or caused a Nvidia driver breakdown. Where other games namely SF4AE was lagging too after I run this beta. Restarting the computer fixed it.
GPU-Z, GPU Core Clock was effected, idling at 405Mhz. When its should have been 50.6Mhz.
I am using Window 7 Home SP1 x64 up-to-date. i3 2120 - 8gig - Nvidia 470 with the latest 301.42 WHQL.
