Lewpy's GPU plug-in is developed using Pete soft plug-in as base. I don't think is better then Pete OGL1 plug-in exept for some features that are available only in glide3 but not very well emulated by wrappers. And, as Zeckensack says "ePSXe w Lewpy's Glide Plugin: looks very well, performs like dog on Radeons. Geforce cards should be okay."
Ciao.
P.S.: I have tested the wrapper with FFVII and the battle menu isn't displayed... probably the framebuffer isn't totally emulated by wrapper.
