Hi guys I have a ASUS radeon r9 280x GPU that I bought because I wanted to be able to play Battlefield 4 with max frames about ~60fps but I constantly get about 30fps it's really annoying.
I have a i5 2500k 3.3Ghz processor, 8gb ram, 850w PSU. And when I check my cpu usage when i play bf 4 it shows 50%? shouldn't it show 100%? my gpu has 47%. Is there any way to get my cpu to go 100% then and how?

280x is plenty powerful for 1080p, so that shouldn't be a problem (i thought you were playing on something like 1600p).

Try doing that and give us a feedback if it worked :D

Your CPU is plenty powerful, and it shouldn't bottleneck 280x. If i were you, i'd try this to get more FPS:

- OC that CPU, since it's a K version
- Install Mantle, since BF4 is Mantle optimized

Also, have you tried fiddling with the settings o_O
On what resolution are you playing?

No, it doesn't. YOu can try overclocking your cpu and also installing mantle and updating bf4.

No problem, i'm glad i could help :D

But it's odd that you couldn't get 40-60 FPS for BF4 without Mantle, since 280x is equal to 770...

Oh well, if it works, all is well :D
