Poor performance since BIOS Update
Hi everyone,
M18x R2, 680m SLI, 16GB mem, i7 3920XM running Win 8.1.
Due to problems with onboard sound I updated BIOS to A12 (from A03) and this resolved the issue. See link for details http://en.community.dell.com/owners-club/alienware/f/3746/t/19582819.aspx
However, since the new BIOS update my machines performance is terrible e.g:
Before BIOS update
BF4 settings on Ultra, AA deferred off, lighting HBAO, Nvidia 337.50 Beta drivers 90 - 120 FPS, BIOS A03
After BIOS update to A12
BF4 setting on medium, AA deffered off, lighting to SAO, Nvidia 337.50 beta drivers 25 - 40 FPS, BIOS A12
Has anybody else encountered this? Can anybody help? I didn't make a copy of the A03 BIOS and unfortunately it is not available on the Dell website. Does anybody have a copy of it?
Regard, Mark
