Playing a game today I experienced some very severe PC side performance degradation, including my machine beeping at me a few times, and supcom experiencing second long lockups intermittently.
My specs are i7 - 3930k, 32gb RAM DDr3, Gigabyte ati 7970, intel 520 SSD (128gb) WD 3TB mech SATA HDD. Somehow, I doubted that FA was really grounding this machine as it's frankly pretty difficult to do.
Second FA Process doubling up on the memory and CPU side resources. I think this is referred to as a memory leak.
