You can use the Magisk module or the .sh script to enable Genshin Vulkan for your device. Most other modules work incorrectly and do not store the device model number. Necessary tests have been done to make sure this module works.
After uninstalling the module, Vulkan is automatically disabled.
You can use MT Manager (bin.mt.plus) to run the .sh
Important
Run it with root permission (su).
Tip
You can use GPU Driver and if you have an old device, you can use MIUI Performance Saver
