Persona 4 40 fps, hits 60 fps if you go to window then back fullscreen
I don't know where to post this, so I'll give it a shot here.

I'm using the latest revision (1614) on Windows 7 RC x64. Specs are a C2D E7800, 4GB RAM, and an ATI 4770. EE and VU Clamps are on normal, the only speedhacks on are the ones down the middle.

I am using the GSDX plugin, latest revision SSE4, DirectX10. I am also using the newly introduced MSAA at x4. I've used both SuperVU and MicroVU.

The issue is when playing fullscreen, I'll sometimes enter a new area to have my FPS drop down to somewhere in the 40's. I ALT+TAB it back to into a window and it instantly hits 60 fps no problem. The weird part is I then ALT-TAB it back to fullscreen, and it still runs at 60 fps. This happens on the map area and the bedroom area.

The game is running at 720p.

Any ideas?

Do you have vsync enabled?

I do, I'll see if turning if off makes a difference
It seems the slowdowns have gone away. I'll let you know if anything changes.

But with vsync on, why would alternating between a window and fullscreen mode fix the problem?
