Well I installed crysis 3 today and was shocked how poorly it uses Crossfire.
Need all 4 cards to work to push my resolution @7680x1600
With only 2 cards the gpu loads are 100% each
With 3 card the gpu load also drops to about 40-50%
When I have 4 cards in crossfire I only get 40-50 % load on the cards.
So my performance is the same with 2 cards 3 or 4 video cards..Wish I could find a fix.
I overclocked my 3930k to 4.8ghz and the fps did not increase nor gpu loads. so its not a cpu bottleneck.
I read that crisis 2 had the same broken scaling for crossfire.
