I installed PCSX2 emulator in my Win 7 64bit machine and tried to load GTA : LCS game, till the cut scene i was getting around 50fps, but once the initial cut scene starts, fps dipped to 4~5. then after i waited for cut scene and played the game fps is still the same. I changed all the settings to low, lowered the resolution to 640x480, but still the same. Does anyone know what is the issue? Any way to speed up the game.
First of all, You need atleast a QuadCore to run PCSX2 compatible games smoothly. You will not get any more than 50fps to the max. Second, check PCSX2 site and forums to see if GTA is compatible ( Not necessary though, if You have a Quad ) and third try changing your Graphics Plugin to lower versions of GSDx and use the Speed Hacks ( Don't use Game Fixes ).
But, your rig is really weak for good games. I used to have E7500 + HD5670 and still had only 48fps for WWE SvR. Try to get an upgrade.
