Its your cpu dude.. Its bottlenecken your system.. I should know.. I use to have an amd k6-2 533.. Well, use petes d3d pluggin or ogl pluggin and press the "FAST" button in the pluggin config.. Then change settings from that to get to your desired graphics.. Check for a balance between speed and video quality.. You can also try the software pluggins too.. And please read all the documents that come with the pluggins and epsxe.. Then check the epsxe FAQS.. This will help you a lot in configuring epsxe for optimal performance on your system..
