When was the last time you used it?
I would also like to point out that I have ALWAYS asked the users to please inform me of any difficulties they find of using the Mod to help me make it better for them. If you have found any sort of crashes, ESPECIALLY, let me know right away! But as it stands right now, I have not recieved any sort of complaints of crashes since Beta 2.
Remember, I can't fix it if I don't know about it.

What are your system specs? I know my PC isn't low end, or even average anymore, but when it was on the average side I was still able to have 20 enemies shooting at me at once while still running at around 17 fps.
Graphics running "out of frame", I've only encountered when an enemy gets knocked down. They will mostly just get back up, but sometimes they'll loop through their entire library of animations until you kill them, which I've been aware of and been trying to fix since V1.06, but this has also occurred (for me) in the official versions of FPSC.
