Anbernic RG405M Performance Regression with version 1.5.1. of GammaOS

GammaOS version 1.5.1. has some real improvements over version 1.3.3. The ability to change performance modes with the touch-screen, rather than a button combination, being one of them. However, when playing higher-end consoles, there is a notable performance regression. In this video, that can be seen with both GameCube and PlayStation 2.

If you want to stick with consoles up to the PlayStation or Nintendo 64, the upgrade to version 1.5.1. is a no-brainer. For higher-end consoles, you may want to stick with version 1.3.3. and put up with a few inconveniences.

Performance mode was used in all tests. Dolphin 5.0-21395 was used for GameCube and NetherSX2 was used for PS2.

Have you experienced this performance regression?

I've also made a bug report over at https://github.com/TheGammaSqueeze/GammaOS/issues/169
