Its Because Of The Better Optimization of Battlefield 4 for the PC. On The Other Hand U can still play it on a fairly respectable fps and without lag if u can tweak it a bit try lowering the motion blur and anti-aliasing a bit. it will give u a boost. worked for me.

Is the r9 270 new? Have you tried uninstalling and re-installing bf3? I know it seems trivial but I had to re-install bf4 when I changed cards.

Well, BF4 makes use of more CPU threads, so it's possible you're getting a CPU bottleneck in BF3. That seems a bit unlikely though, since I didn't think the FX-6350 was *that* weak. It may be a software issue.

Umm... I don't think an R9 270 would run BF4 on ultra with smooth FPS
