I Know exactly what your problem is ..
You are using NTSC-U version ..
if you use the PAL version you'll never get any lag and the game will run very smoothely
be sure to rip XA Streams to MP3 and use Enhanced XA Detection ..
the only disappointment is that the music is different from the NTSC-U version .. it is not the same CREEPY and SCARY music but it is not that bad ..
if you want to stick with the old music try the old RE with no director's cut NTSC-U version .. that should do it ..
