I've got a Voodoo 5 5500 running on a p3 933mhz, 512 mb ram box. I didn't think i'd have speed problems with n64 emus since my playstation emu works beautifuly. But thats just the newbie in me not understanding that all consols are different and the n64 is extremely difficult to code for.
I basically can't find the right plugin for my card, that gives me a good cross between quality and speed. Also should i be using a glide wrapper as I think that might be what started my problems.
I got rid of it and it definately helps, also disabled chang blending mode if invalid for card seemed to really help for some reason. I have everything else enabled except frame buffer emulation as it seems to really slow down the system for some reason unless i choose BLACK option.
