try this combination :
pcsx2 version : 976
-speed hacks : x1.5 cycle rate , INTC Sync Hack ; Enable IOP x2 Cycle Rate and WaitCycles Sync hack (you can let this one disabled if you want) and the others disabled
-advanced : all to nearest , none ; enable flush to zero and denormals are zero
-CPU : VU SKIP
-Graphics : GSDX 962 0.1.15 (NLOOP Hack and Texture filtering on grey ; D3D internal res : 1900 x 1400 ; native disabled )
using this settings i play the game at almost full speed (90-95% , when i play it on fullscreen i don't even realize that it isnt' full speed)
My system specs : Intel E2180 Dual-Core @ 2Ghz(not overclocked) ; GeForce 9500GT(512 mb) ; 2GB RAM ; Windows XP SP3(i don't know if this matters
i hope i somehow helped you
i have another problem with this game ,at the Z Survivor for example , at the 3rd fight (my character - gohan) after i win , it "freezes" but the character still "moves up and down his body" if you know what i mean , while standing still , when the camera approaches his face , then it does nothing , when the "result" screen is supposed to appear it just doesn't , if you can help me i would be really happy ^^.
btw , i am using the PAL verion of this game.
