Here is my current setup:
AMD Phenom II 1100T Processor (3.3GHz)
Gigabyte 870A UD3 motherboard
8GB Ram
Radeon HD 6950 GDDR5 2gb
750 watt
When the match starts, and there's nothing going on, it i'll hover around the mid-upper 40's. Once the fighting starts, though, my FPS quickly drops to the 30's and often dips into the 20's. There are some levels, especially when I use my heat vision, that my FPS just stays in the 20's-low 30's.
BTW, my graphics settings are bottomed out...everything set to Low with no AA, and it's been like that for the best year. When I first got the computer, it ran MWO on medium-high settings just fine.
On the systemrequirementslab.com, it shows that my computer should have plenty of power to run it. I bought the computer in 2011, so I don't know if it's simply time for some hardware upgrades or if I have a software issue going on....

Any advice?
