Well, at least some things are working for you know, BTW Glide 64 does NOT falsely report FPS, it merely reports 1/2 the value of the actual FPS (for some reason unknown to me with my lack of programming skills

) To speed things up get a faster processor, or O/C your current one, N64 emulation is mainly Processor intensive, not so much video card intensive.
To O/C your Video card (if you are interested in that still) google 'Rivatuner' a neat tweaking utility for Nvidia and ATI video cards.
Glad it helped you a bit!
