Just posting here to see if anyone else is still getting bad frame rates in BF4, because i am. Starts off well with about 125fps, then drops to about 60-70
System:Xeon e5-1620
Asus Rampage 4 Extreme
2x Sapphire R9 270x's (4 gb)
16gb of Team Vulcan 2133
750watt Corsair PSU

Ideas?
 
Generally, random frame drops without heat issues would be either driver, network, or power related. Corsair power supplies tend to have not so reliable amperage on the 12v rail, namely when you are going to the upper ends of its rated supply. Not enough to destroy a card in most cases, but it is enough to hamper its performance. What model is it, the only one I would use with crossfire is the HX750.
