If you are having problems running Lock-On (harddrive overload, not enough memory, bad fps, seemingly laggy... etc) you might want to give this article a try to see if it is a background program in Windows that might be the cause?

How to perform a clean boot to prevent background programs from interfering with play (this way you can work backwards and eliminate the causing factor, if there is one).

Hmm, Lawndart, I tried the first couple steps that Microsoft gave from your links to perform a clean boot, but one of the steps requires me to "disable" some programs such as anti-virus, video device DRIVERS, joystick profiles, etc. I do not understand, if I disable these, sure I might get better frames in LOMAC, but I will get virus's, my video card won't work, and my joystick will go a-wall. Is this process simply to eliminate variables one by one, so that you can find out exactly what is causing a problem? The reason I'm asking, is because like everyone else, I could use a couple frames, but I'd like to be able to fly with my joystick, and not my mouse

Think I'll quote myself on this one.

I don't disable a whole lot of things when I fly, but if you have problems it's a way to troubleshoot and identify at what point the game starts getting sluggish, by enabling background ops one by one.

I do turn off things such as auto-update, anti-virus, Win firewall (useless), internet security or anything that could slow down connection speed or randomly start chewing the harddrive while flying. I use some of these while not flying, but we do or die when it comes to lag!
