Dude!! I got almost the exact same computer specs as you do.. Check my profile.. All my games run near perfectly for me.. I use lewpys glide pluggin most of the time and petes d3d pluggin sometimes.. Try playing your games at 640x480 with 4xFSAA on using lewpys glide pluggin.. Or 1024x768 with no FSAA using lewpys glide pluggin.. For pixelated 2d though, you can't beat using the first config.. If you need an exact configuration for a game of lewpys glide pluggin, let me know.. I got all of the games you mentioned so far.. And do also read the documentations that come with epsxe and the pluggins like the fellow above suggested..
