Stiv I am also experiencing this issue, beginning the moment I completed the 1+GB update pack origin had waiting for me today. After the origin update I am having the flashing color issue but I am not using any Nvidia cards, I have XFX 7970 Ghz edition crossfire x3. I am currently using 13.11 catalyst drivers, and tried both reinstalling the drivers, as well as downgrading the 13.9 all with the same results. Also, I am experiencing framerates around 60FPS in single player, using 3 crossfire cards both at 5760x1080 eyefinity, and at 1920x1080 and 1920 x 1200. If I drop settings from ultra to low, I get nearly 100FPS, but I am reading about users with Nvidia GTX 780's SLI hitting as high as 200FPS!?
We need a chart for MAX fps we can expect with crossfire setups, SLI setups, and single card setups so we have an idea of whether we are hitting the performance marks we should be getting, or if something is wrong, which is what I expect. is 60FPS normal for eyefinity 5760x1080 with triple crossfire 7970 GHZ edition, 32GB memory @ 2400MHz and an 8 core 4.4GHZ CPU using Samsung 840Po SSD? I feel like this is the best game ever made but it is plagued by poor performance and users like me who spent nearly 10k $ on systems to exclusively play this game need some explanations/direction/hope that these problems are being acknowledged and worked on. Is this color rainbox flickering issue reported to be effecting AMD users as well as Nvidia? Thank you
