In order to help you further with your problem, please make sure the following are all provided.

• The version of PCSX2 you are using.
• Any non default settings you are using.
• What games you are trying to play and if you are playing them from ISO or DVD.
  

Thank You.

try VU cycle stealing at LV-2
if still slow you need to get a Phenom or Intel-i CPU...and a gddr5 video card

i upload some pictures, and you say me what to do,

Start by disabling ALL game fixes.

Try these

• Change the Round mode to Nearest and Clamp Mode to None in Both EE and VU's section.
• Use Speedhacks : All the Reccomended ones and EE Cyclerate to 2 and VU Cycle Stealing to 1
• Use Native Resolution and disable Texture Filtering
• Change Windows Power Plan to High Performance : Important
  

Also, I heard that its better to use 30/25 as FrameRate in pcsx2_vm.ini.

Well, thanks, but one problem, my fps is lowing in some effects, like sun

What do the ee% and gs% say when you get those slowdowns ?

umm... Wait a second
EE 54-47%
GS 70-50%

Tried enabling/disabling 8-bit textures ?
