FF-VII-CRISIS CORE lag problems

[StrifeDemonVII]

Win 64 (running java and jpcsp on 32 though)
2g ram
ATI Mobility Radeon HD 4200
Total available graphics memory 893 MB
AMD V120 Processor 2.20 GHz

Using Jpcsp r2041 build

So ive tried tweaking some configs but it seems almost completely unplayable between 5-10 fps in actual gameplay, the graphics seem alot more choppy than ive seen on some of the help videos too...any advice?

Try older revisions like 2002 and see if it helps you. Set maximum method size to 100.

all i can say is that ur clock speed is seemingly low? im just new here

What are your settings. Turn off vertex. That seems to slow down a lot of games but actually speed up others.
