Cemu, the popular Wii U emulator for PC, has received yet another update! This marks the release of version 1.15.7c, which is now available for download to the general public.

The update adds controller information to the on-screen overlay, which is used to show useful info about the active input profile when launching a game and also includes a new, optional low battery indicator (turned off by default). The CPU JIT recompiler has also been improved, thus helping to further reduce microstuttering in-game. A good number of issues and oddities were also addressed, such as a crash occurring when using invalid shaders and some framerate issues with a few games. As a result, titles such as Pikmin 3, Paper Mario Color Splash and Yoshi's Woolly World should run better using this version.

You can read the official changelog below:

# Cemu detailed changelog for 1.15.7c
# Patreon release date: 2019-05-17
# Public release date: 2019-05-24

# New in 1.15.7c:

general: Enabling the overlay should no longer cause graphic bugs in games

# New in 1.15.7b:

CPU/JIT: Fixed a bug leading to random corruption of the instruction stream

# New in 1.15.7:

general: Added visual indicator at game boot which displays the used controller profiles
general: Added controller low battery warning (can be turned on/off in settings. Off by default)
general: Global precompiled shader setting should no longer reset to auto (#63)

general: The internal process of updating system.xml is now more robust
Previously there was a slim chance to lose all settings when Cemu crashed or was force closed
while settings.xml was being updated

CPU/JIT: Optimized recompilation. This process is already fast enough to generally not be noticeable but
it can lead to delay and micro-stutter in cases where a lot of new code is recompiled at once
Examples where the bottleneck becomes apparent:
Frame drops or audio crackle on first loading screen
Initial delay when booting a game
With the optimization, these should now be slighty less severe

GX2: Improved the accuracy and behavior of GX2WaitForFlip + GX2SwapScanBuffers
This fixes an issue where games would run at the wrong framerate (e.g. Paper Mario Color Splash)

GX2: Fixed a bug in texture decoder for format BC4 (#59)

GX2: Fixed an issue where Cemu would crash if a game setup invalid shaders
This resolves crashes in Pikmin 3 and Yoshi's Woolly World

Note:
(#xx) refers to bug tracker issues fixed by this change. See http://bugs.cemu.info/projects/cemu/

I still have 1.15e - is the improvements huge compared tot hat version?
I rather not do all the texture caching all over again (and no, copying the cache does not solve this issue)

I wonder if we ever get a build like dolphin / pcsx2 etc where caching is a non-issue.

that team is doing incredible and made good money with their Patreon
I wonder if they will do the same for the Switch? have they considered it? or maybe they are already behind one of the WIP emulators?

that was rather fast.
the last update before this was released not too long ago.

The CPU JIT recompiler has also been improved, thus helping to further reduce microstuttering in-game.

This is probably a stupid question but I’m going to ask anyway. Why not simply patch games before playing them? Loading the game for the first time will take way longer but it should improve performance. Emulating modern systems is a very intensive task.
