The finest 3DS emulator out there, Citra, have made contact with the outside world to let everybody know, no, they are not dead, having not published any progress reports since early 2020.
This status update comes with a huge list of improvements that have been made to Citra along with a special announcement that one of Citra’s most requested features is now in development – The implementation of the Vulkan graphics API into Citra!
The update states that Developer GPUCode is adding a new Vulkan backend to Citra, which promises to significantly improve graphics performance. Vulkan provides lower-level access to the GPU, allowing for optimizations not currently possible with OpenGL.
Initial tests show that with some configurations, game performance can more than double, with Android devices receiving a significant speed boost.
This is particularly beneficial for devices with Mali GPUs, which commonly have poor OpenGL ES drivers. The new Vulkan backend will make Citra more accessible to many more people, not just those who have a Snapdragon SoC. Additionally, using Vulkan will allow support for Citra to be brought back to thousands of Mac users who were unable to use the previous version due to changes in Apple’s OpenGL support.
Below is a full list of the features included in the update published on the Citra website on 28th March 2023.
