FPS drops over time

Sage009 · 07-29-2016, 08:16 AM #1

Using Dolphin 5.0 in OpenGL while playing Project M netplay, the first match and main menu FPS is a perfectly fine 59-60. However, every subsequent menu and match lowers my average FPS. If I play long enough, I can drop my FPS down to 20.
I have no idea why this happens, and it has never occured in any previous build of Dolphin.

You're right, checking that worked. Thanks.
I'd still like to know what the problem is and why that fixes it, though.

From brawl wiki page

"With Friends" Menu Problems
After connecting to the Nintendo WiFi Connection, when you enter into "Brawl", "Friend roster", "Team Multi-Man Brawl", or "Home-Run Contest" sub-menus the game will suddenly drop to 1-5FPS and display Src\PixelEngine.cpp:193 W[PE]: (r16) ALPHAREAD errors in the Log. This is due to a known slow/problematic codepath, and can be avoided by enabling Skip EFB access from CPU. This error only appears when interacting with Nintendo WiFi Connection menus. See issue 6553.
