How come Pcsx2 only lags on me in fullscreen. It runs perfect when I play it in the window form. I just really want to play fullscreen mode. I used to be able to play fullscreen but after I reformated it, I couldn't get it to work in fullscreen again. I also tried installing the beta but same thing. When I click the fullscreen button, the CPU% on the top goes from about 10-30% to about 90% for some weird reason. It drops from 60 fps to about 10 fps. I am also using PCSX2 0.9.6.

Computer Specs:
Windows Vista Ultimate 64 bit
Intel Core 2 Duo E6750 @ 3.2GHz
EVGA 9800GX2
4G(4x1GB) 4-4-4-12 Corsair XMS2 RAM

PCSX2 Specs:
GRAPHICS
GSDX 890(15.00, SSE2) 0.1.14
CPU
EERec checked(everything I name is checked)
VU0rec
VU1rec
Multi thread GS mode
Limit Frame
everything else I left default.

switch to SSSE3 gsdx that cpu supports it.

that's not how you go fullscreen (that's maximizing the window, which is not fullscreen >_>)
To go fullscreen you have to set the "Resolution" option in gsdx to the size you want for DX9 or set that option and then hit "Alt+Enter" for DX10

Alright thx guys it stopped lagging now after I changed the resolution.
