Hi VickM! Please don't do anything about changing priority of TF2 (above normal at the absolute max) as it tends to cause stability issues and doesn't really do anything with performance anyway.
Someone posted on Ozfortress a couple days ago in a thread titled "Game Booster". It's some form of Razer software (which I found shifty and gimmicky sounding at first) but there's a few testimonials in there, one of which belongs to probably one of the most reliable people on Ozfortress.
From my understanding unfortunately, it requires you to own a Razer product, but I'm sure you may be able to acquire it/use it by "other" means.

Hope this may help you.
Also, you don't need the -noforcemaccel etc launch options - m_rawinput 1 overrides those (if you use it, anyway).
