Hello,

SPECS
PSU: 850 w xfx
Ram: 8gb corsair vengeance
Motherboard: Asus sabertooth 990 fx r2.0
CPU: Amd fx6300 @3.5ghz
CPU cooler: corsair h60 water
Gpu: xfx radeon 280x & 280 Factory OC version
Monitor: 3x HP s2031 running @ 4800x900 eye infinity


I have xfx radeon 280x and factory OC 280 in crossfire. I run triple monitors and I use to get 30 fps with only the 280x on ultra. Now I am get 60-80 fps in BF4 but terrible lag spikes. I lowered down from ultra to low and I still got big lag spikes. I decide to try it in campaign and I'm getting over 70 FPS constant with no lag spikes. My ping is always under 70 so I don't think it is that. Could it be a bottleneck because I am willing to overclock CPU. Is there something I should do to fix this problem?

Thanks in advance.

You need to over clock your fx 6300. Bf4 multiplayer is extremely CPU intensive , even my i5 3570k at stock a much stronger CPU then yours had framerate issues before a strong over clock.

Yes I updated all my drivers. The problem is I didn't have so many big lag spikes when I didn't crossfire. In multiplayer, on HIGH I kept a stable 40-45 FPS with no crossfire( just 280x).

I overclocked my cpu to 4.3 ghz and still no improvement. I get between 15-20 on low and 5-10 on ultra.
