[GC] FPS drop in Super Smash Bros Melee 4P Mode

[CodenameD]

When I play SSBM(EU) 2P mode or vs 1 CPU, FPS is around 50 - 60 FPS (which is smooth and fast enough for me).

When its vs 3 CPU it drops to 35 - 40 FPS (which is playable but feels laggy).

My spec is -

E5200 @ 2.5 GHz (CPUs: 2)
1 GB RAM
NVIDIA GEFORCE 210 1 GB DDR3
Windows XP Pro SP3
Dolphin 3 (3.0-201-dirty)

I run this with the following settings-

Enable Dual-Core: On
Enable Idle Skipping: On
Backend: D3D
Fullscreen: 800x600
Internal Res: 1xNative (640x528)
Anti-Aliasing: None
Anisotropic Filtering: 1x
Scaled EFB Copy/Per Pixel Lighting/Force Texture Filtering/3D Vision all off
EFB Copies: Texture
External Frame Buffer: Disable
Fast-Mipmaps/Disable Per-Pixel Depth: On, rest all off
DSP HLE Emulation
Enable DTK Musing: On
Audio Backend: DSound
Sample Rate: 48000 Hz
Enable EuRGB60 Mode (PAL60): On

Can anybody tell me if I can optimize it further by changing settings or using an earlier version of Dolphin. Ask me if you want any other configuration info or whatever. Thanks.

Your hardware is not good enough to handle 4 players. Your need a better cpu.

So if I OC it, will it be enough? I heard E5200s are good overclockers!

Or do I need more cores or something?

Although it's recommended that you upgrade your hardware enable to fully enjoy Dolphin, I see no loss in trying to OC first.
