What Video card settings should I use with JPCSP and which config settings go faster?

[chessplayerjames]

Okay, I have JPCSP v0.6 1975 32-bit (Windows 64 bit OS though). I am currently playing Kingdom Hearts Birth By Sleep, and a lot of the times, it either slows way down or it just stops altogether, but it didn't used to do it so often. Here are my computer specs: Windows 64-bit Ultimate, Dual core intel processor @2.5ghz per core, 4gbs ddr2 RAM, 500gb HD, 500mb video card (nVidia GeForce 9300 GS series) and onboard sound, if that makes any difference. I want to adjust my settings so that JPCSP can go its fastest. And one other thing, I set JPCSP to go into 640x480 resolution whenever I start it, so that it will be bigger, without actually changing the zoom size (changing zoom size doesn't work at all -_-). Is it possible that will slow down the emulator? And if it does, if I changed it for a larger (smaller JPCSP) resolution, would that make it go faster? Here are the options I have selected in JPCSP:

General: Save window positions on exit.
Video: No options selected.
Audio: No options selected.
Memory: Ignore invalid memory access.
Media: Use media engine; Decode audio files with Sonic Stage
Compiler: Use Compiler; Maximum Method size...50

Okay, I want to speed up JPCSP, without disabling audio, because auido rocks. Ever watched a movie without sound? Kind of the same thing, so I don't want that. By the way, will making the maximum method size larger or smaller be faster?

Okay, I am going to list my video card setting here:

Anisotropic filtering: Off
Antialiasing - Gamma correction: Off
Antialiasing - Mode: Off
Antialiasing - Setting: None
Antialiasing - Transparency: Off
Maximum pre-rendered frams: 0
Multi-display/mixed-GPU acceleration: Single display
Texture filtering - Anisotropic sample optimization: On
Texture filtering - Negative LOD bias: Allow
Texture filtering - Quality: High performance
Texture filtering - Trilinear optimization: On
Threaded optimization: Auto (BTW, does JPCSP support multi-core?)
Triple buffering: Off
Vertical sync: Force off

Okay, remember, I want performance over quality. I don't care if I lose a few pixels and somebodys face looks like they had a bad plastic surgery, I just want to be able to play the game as fast as my computer will allow. However, I do want to keep sound. Thanks in advance for your help, and sorry for all of the post, cause its really long. Thank you makers of JPCSP, I like it a lot.

BTW, I noticed using CW cheat slows down the game. Is there anyway to bypass that or no?

Thanks again.
