Hello fellow forum members,

I have been running into a little problem lately. the problem is prefomance when i play GW2. I use 2 Graphic cards Sapphire HD6870 both are the same 1GB each in Crossfire. On maxed out setting 2 cards i run @ 16FPS, with a single card also maxed out setting it’s between 40 and 50FPS. Does anyone know what can be wrong i lookad at my settings and as far as i can see nothing is wrong. I know that the cards are still 1GB but becourse i have two i have more raw power in the end.

Probably ur PCI-e bus speed is going down to x4 when u activate craossfire which causes poor frame rate

U need to be at least at x8 (both cards) to bypass the bus bottleneck in GW2.

I have used the gpuz that comes with my republic of gamers mainboard. The lanes are working @ x16. But on THE bottom it states crossfire is off and catalist control centre says it’s on and in the bios it’s says the same.

It may be aswell a driver issue, try clean all the drivers and get the 13.1 for a fresh install. I guarantee GW2 supports crossfire properlly, so the problem definitelly has to be on your side. Did u tryed unpluging the cards and plug them back in?
