News - Cemu 1.7.4 (Patreon)

Cemu 1.7.4 is scheduled to release on 2nd April. As usual, the update will be available for 5$+ Patrons first and then a week later (9th April) for everyone else.

Important things first, here is the BotW preview video for 1.7.4:

We'll leave it up to you to spot all the improvements! Disclaimer: Compared to Cemu 1.7.3, the FPS will not improve.

Btw. if you want to discuss BotW or Cemu in general, we really recommend joining the discord or subreddit. Patreon's community and comment pages easily get cluttered with too many comments and it's hard to keep track of individual conversations.

General upcoming changes

The upcoming Cemu version is mostly a bugfix release. The changes include:

• Graphic improvements
• Minor optimizations in the graphics backend
• Minor tuning for shaders to speed up compilation
• Graphic packs now can alter texture formats and not just the resolution
• Lots of bug fixes

Fixed flickering due to buffer cache

We finally managed to track down and fix a long standing bug that caused model flickering under very specific conditions. This issue was most prominent in Twilight Princess HD, but it also affected other games to a lesser degree.

Example video of the flickering: TPHD 1.7.3d (watch the horse's body, it sometimes disappears for a split second)

In 1.7.4, this issue is now resolved and TPHD is 100% flicker free!

We also decided to make the 'GPU buffer cache accuracy' setting a game profile option (additionally to the UI setting). Which means you will be able to configure different values per game.

More control over textures for graphic packs (Slightly technical)

Cemu 1.7.4 introduces a new property to graphic pack texture rules. This property is called 'overwriteFormat' and allows to respecify the data format of a texture. For example, using this property it's possible to turn a 16bit depthbuffer into a 32bit depthbuffer for additional depth and shadow accuracy. Another use case would be to increase the color bit-depth of framebuffers in order to reduce color banding.

But there is another use too. On NVIDIA GPUs textures in SNORM format are pretty limited, leading to bugs in games that heavily rely on them. One of those games is Super Smash Bros for Wii U. On NVIDIA, this game appears overly dark. Using the new graphic pack property, this problem can easily be circumvented by using an alternative non-SNORM texture format for the framebuffer. Put more simply, Cemu 1.7.4 will offer a workaround for the SSB4 darkness problem with no negative impact on performance or any other graphical degradation.
