INTEL CELERON [email protected]
XFX HD4550 512mb DDR2
2GB Kingston DDR2 667mhz
Using 0.9.7 r3113 version
GSdx Settings:
Resolution:640x480
Texture filtering: on
Allow 8-bit textures: off
DX 10/11 mode,hardware ofcourse
Almost all speedhacks enabled,except the last one in the down right corner,that causes black screens,cant remember its name lol
What screenshots do you need?

dont enable all speedhcaks, untick them all, then reenable them 1 by 1. and test each time you do so.

moreover, set gsdx internal res to native.
Your cpu may be a bit weak though. Don't expect miracles.

Damn still slow
Anyway,other games that i have tested work fine
Rock band and rock band 2 work at 60fps constantly
Yakuza also works at full speed
Budokai Tenkaichi 3 works at around 45fps but its fully playable with no slowdowns
Only game,beside this,that is slow is GT4.
I guess my graphic card is too weak for those games
