I have tested the same game on 2 pc's GRAN TURISMO 3 and sometimes Gran turismo 4

First PC

  • Core 2 Duo E7300 2.66 overclocked at 3.1 GHz (safe) it has 3mb of L2
  • Radeon hd 4650 Pretty ok graphics card for the 4xxx series (512 MB)
  • P31-ES3G gigabyte
  • Windows 7 Ultimate
  • 2Gb of DDR2 memory 667 MHz

On this PC i get about 17 Frames in game while racing and 60 on menus and 30 when 3D cars rotate in selection. I see some improvement after the Overclock

Second pc (this one has ton of ram and video memory but no processor power)

  • Core 2 Duo E4600 2.4 overclocked at 3.0 GHz (Thats 1.5GHz per core) (Safe) It has 2mb of l2
  • Redeon hd 6570 2Gb of ddr3 memory
  • 945GCM-S2L gigabyte
  • 4Gb of DDR2 memory at 667 MHz
  • Windows 7 Ultimate

On this PC i get about 12 Frames in game racing 60 on some menus (not all) and when 3D cars rotate <20 Frames. Also i see some improvement after the Overclock.

First PC is pretty solid machine why cant it handle PS2 games? Gran Turismo 3 is not the only game i have tested on both machines but it has solid 3D graphics so i use it as a benchmark and i really wanna play this game.

Is the emulator only Processor hungry or?

I know that the PS2 doesnt have a lot of ram and a lot of processor power why cant i handle it? Can some1 please give me a detailed answer what kind of specs do i need and yes i have all the setting set fine in PCSX2 (everything but 3D is a problem)

Thanks for for taking your time reading this and leave a comment if you have any questions.

PCSX2 is extremely difficult to get working well. Almost every game requires different settings, and every machine will require different settings. It took me hours to get a game stable, and then it still wasn't working well. We can't really answer this question, it all depends on a hundre factors –  Simon Sheehan Aug 13 '12 at 3:18
    
The other issue is that an emulator takes around 10x more power than the original system did, and it's not optimized in the same way. PCSX2 is a long work in progress with maybe only 60 games fully stable, out of thousands of titles –  Simon Sheehan Aug 13 '12 at 3:19

You'll want to do a lot of research, and visit the PCSX2 forums. They have a LOT of detailed information there and guides –  Simon Sheehan Aug 13 '12 at 3:23

Don't worry, my quad core struggles even. Also it's 3GHz per core - its not divided into two ;) –  Simon Sheehan Aug 13 '12 at 4:54
