Bf3 low frame rate and screen glitches - CPU Problem?

AngryStud1 · Aug 5, 2013

While playing battlefield 3 single player, I normally tend to get around a 60-70 fps rate average while playing on ultra settings. After beating the campaign earlier yesterday, I decided to try out multiplayer for the first time, and noticed a significant drop in frame rate while playing online. On servers with around 32 or less people I was getting around 34 fps average, but on 64 player servers my frame rate became almost unplayable (around 19-22 fps average). Sometimes when I play online my screen will glitch out (It's hard to explain what exactly it looks like) and makes seeing anything 5 feet in front of me literally impossible. It's been annoying me a lot as of recently, so I decided to do some "testing" to try to find out the culprit. I joined a 64 player server with my phone hooked up to my msi afterburner server, to check my gpu usage while I was playing. Throughout the whole game My GPU usage went from around 55%-80%, with some spikes of 85% when things got really graphically intensive. I then used the CPU frequency monitor on AI Suite II to watch my CPU usage while playing, and I was getting 100% usage across the board. With this in mind, I figured it would be best for me to try playing on lower settings, so I went from ultra settings to low settings, and noticed absolutely no change in frame rate. In other words, I had almost the exact same frame rate on lowest settings than I did on ultra settings, maybe with the exception of 5 extra fps on lowest settings. This is leading me to believe that my CPU, which is the bottleneck of my build, is what is limiting my frame rate by so much. Here are my PC Specs:
Motherboard: Asus Crosshair V Formula-Z
GPU: MSi R7770 OC edition, 1GB ddr5 RAM
CPU: AMD Athlon II X2 B24 Duo Core @ 3.0 Ghz
PSU: Antec Earthwatts 650 watt power supply
8gb of 1333mhz ddr3 Ram

Am I correct on my assessment? Would upgrading my CPU to an FX 8350 (which I plan on doing anyways) help boost my fps back to something manageable while playing online servers, or is it my graphics card that is limiting me?

your cpu is the problem here because bf3 is really cpu intensive on big maps and alot of players, 8350 would definitely fix the problem

Thanks for the reply on such short notice. It's glad to hear that my assumption was correct. Hopefully once I upgrade my processor I should start to see some decent and playable frame rates in multiplayer. In the case the CPU is limiting my frame rate, is it also the culprit for my screen glitching out the way it does in multiplayer, or is that just a problem with the game or my GPU?

could be the drivers but maybe cpu is stressed to much so it cant take that much items on the display

As my drivers are up to date, I am going to assume that the CPU is in fact the culprit to the screen messing up the way it does. Again, thanks for the reply.
