Fix for PSX4Droid Lag Identified

You may or may not know XDA member zodttd. If you use PSX4Droid (an Playstation 1 emulator for Android), then you owe this dev a thank or two as he is the one that created this app. The emulator runs fantastically well on most devices but it has a problem. As time goes by, performance decreases (you may see FPS drops). After seeing this, zodttd decided to look into the problem and found the culprit coding for this. He has provided his findings as a guide for devs to cook this solution into their kernels and roms.

Please leave some feedback for the dev in case you find some other “oddity” in the code.

Hi,

I am the author of psx4droid. It’s a PSX emulator that uses a dynarec. Due to the nature of this code I can have to invalidate the instruction cache on these Android’s ARM processors. Just like Yong must do in GameBoid.

I noticed performance loss on the Evo 4G, MyTouch 4G and potentially others. As do some people running GameBoid (though this emulator lays heavy on frame limiting as it runs faster than 60 FPS so it’s not noticed as much).

You can find more information in the fix thread.

PSA: You Can Optimize Your Note 4’s Recents Menu & RAM

The Note 4 never had the fastest Recents Menu, and despite its 3GB of RAM, its app-holding capabilities only got worse on Lollipop. The infamous RAM bug that plagued the S6 is indeed an annoyance on the Note 4's 5.0.X ROMs. Rumors of an update to fix all of this were confirmed with the first reports of the 5.1.1 update for the Russian Note 4, which seemingly improved the Recents Menu and RAM management. But it'll be a long time...
