I upgraded from 413 to 420 hoping to eliminate momentary freeze-ups which lasted a second or two but 420 also does it, maybe even more. I am running full install, with cachesizemegs set from 12 to 18 to 24 to now 32 with no improvement. I'm running 3dfx Glide with dual Voodoo 2's, A3D Vortex-I with stereo surround sound OFF. Other sys. specs: P-II 450, 128MB, STB Vel 4400 as main card, DSL hookup with 3COM e-link card. HELP!!!!!!!!!!! THX!!!!!!!
