On guild wars 2 im getting around 50-60 fps on normal gameplay and dropping to low 20's during big events making it nearly unplayable, also when i change my graphics setting it doesnt seem to make a massive difference.
I put on precision x to look at my GPU utilization, and both cards are running at around 45-50%, when I turn SLI off Card 1 goes to 99% making me think that something is bottlenecking, and it makes no difference to my FPS, but that seems strange as when I run other new games both cards run at 90-99% and SLI makes a big difference as it should do.
Operating System: Windows 7 Home Premium 64-bit
Processor: Intel(R) Core(TM) i5 CPU 760 @ 2.80GHz (4 CPUs), ~3.4GHz
Memory: 8192MB RAM
Graphics: 2x NVIDIA GeForce GTX 470
Display Memory: 4049 MB
PSU: Antec truepower 750W
I have the latest nvidia beta driver: 310.54
So basically is it time to upgrade my CPU or is it just guild wars 2?
GW2 is not optimized for sli so your system is fine. Some games just don't use sli well and really nothing you can do about it on your end, even changing cpu will not change it. It was talked about in the gw2 forums upon release about the poor sli performance. In the future they may work with nvidia to improve this as they did add better triple monitor support a few months in. At first skyrim didn't support sli at all and great strides came later for support.
