Area 51 (Midway PC) & Quake 4 graphics issues

I am running a 3 GHz PC, 2 Gigs RAM, Radeon 9250 256 MB card.

Area 51 runs very choppy until I run the update patch A51 US Patch 1 2,
Then everything has a white outline, it smooths out a bit and is at least play-ably smooth.

Quake 4 has some kind of strange color problem and looks like a television that can't pick up the station properly.


Any recommendations on fixing these? Far Cry, Doom 3 and other games with great graphics run great at the highest or at least medium high setting.

 

Area 51 seems to be slowing in part because of the built in mouse smoothing effect.

I can't find anything on Google about disabling it, if anyone knows how, please let me know.
