And I have been downloading since 8PM,

Done a whole bunch of tests and research for Sli settings. those whose using Sli's should be aware of this.

Nvidia beta driver for bf3 is not stable for SLi. by using Nvidia inspector, found that bf3 profiles for Sli is not optimized for OC'ed GCs. yeap, overclocked cards (which includes factory-OC cards). mine heats up too fast and crashed before, same goes with some other Sli users worldwide experienced the same. What i did was to retuned the clock to standard non-OCd gcs (675Mhz for me 460gtx sli) and solved everything. this probably due to bad nvidia card profiling. dun forget to force alternate frame rendering 2  . ran on ultra quite good but i preferred low setting since cant spot ppl nicely on ultra. 

just hoped that the released ver of bf3 would have no bugs.

yeah i had that problem this morning, stucked at 100% then suddenly revert back to 74% still downloading..in the end i cancel download and need to re-download the damn thing again haish.. now can play de
