I'm curently playing MH3 on Dolphin r7723 but the screen is too bright so it caught lag.
How can I lower the bright ???
Could you post a screenshot?
Reduce the brightness of your monitor/screen?
btw: Your Dolphin revision is a little bit outdated

idk why but I had tried to use the newer Dolphin but it lagger than this one,and I idk where the srceenshot had gone when I take the srceenshot btw Im using Mac OS X
Screenshots are saved in Dolphin/User/ScreenShots
yeah I had already looked in it but it no where to be found
Are you sure, you press the right button? (F9)
Try to make a screen capture (with a capture tool)
btw anyone know which Dolphin is best for MH3 ???
Well, just try some revisions and choose the one which works best for you.
Hint:
older revisions: Faster than newer ones, but less accurate
newer revisions: Slower, but more accurate.
Dolphin 3.0: balanced between speed and accuracy
