LOL, don't blame me.
What do mean when you say the weapons are slow?
IMHO UT3 blows UT2004 away in every aspect, And I really love the graphics, yes you need a pretty powerful rig to take full advantage of UT3, I play it maxed out @ 1920 x 1200 and its a good time.
Lately I play under the name: iBlast and MurdaOne, are you still using Primus?
