All options have been tested,drivers from 10.2 to 11.3 without effect. Bloom on/off,Settings low/high,etc etc.
I'm using now 11.4 beta drivers and black screen only two times at hour.
Main problem is Gigabyte mobo with 2 pci-e x16 slots,yes both cards with x16 speed. If i have only one Card installed,then i can play without Black screen. NVidia or ATI,if you have Gigabyte mobo you have problems on Vanilla BFBC2.
