JPCSP for Dummies

[gid15]

I think I have a pretty generic problem on the forums: my emulator runs unplayably slow. I try to run Fate/Extra, and no matter what config I set in the Video section, I simply can't get more than 5-8 fps. Character's don't have voice either, although I have SonicStage installed on my computer. I have Java 7 update 21, and jpcsp r3040. Specs:

• Intel P4 3.00 GHz x2
  
• 2 GB RAM
  
• ATI 5670 HD (1 GB)
  
• WinXP sp2
  

Maybe my rig just doesn't suit for this... but being a Type Moon-fag doesn't let me to leave it.

From your log file:

Code:

03:03:24  INFO      emu - GUI -     [ ] Use Software Rendering (very experimental, not yet complete, slow)

I see that you have selected all the "Disable something" options. They usually have the effect to reduce performance. Have you tried simpler video settings, e.g. only selecting "Enable saving GE screen to Textures instead of Memory".

Also, have you tried to reduce the value "Maximum method size" under the compiler settings, or select "Ignore invalid memory access (not recommended for test reports, but improves performance)" under Memory settings?

Other features like Frame skipping (under Options -> Video) or changing the clock speed (under Options -> Clock speed) might also help.
