Shaders have instructions inside them for the GPU to perform various types of operations.GPUs use small programs called shaders to control the GPU rendering pipeline.(Games might use Vulkan, but we are yet to see any games using it)
The Nintendo Switch has an Nvidia GPU and games can use either OpenGL or NVN API (Nvidia proprietary API), to communicate with the GPU and render visuals.(If you are interested, you can check out the homebrew here.)īefore we get into deeper technical details, we need to understand a few things: With some progress, it was now time for him to implement shaders on the Vulkan renderer. He used existing switch homebrew like SpaceNX and Push A button, and later wrote his own homebrew app of a blinking screen and got them to render using the Vulkan renderer successfully. Rodrigo started experimental work on the Vulkan renderer, with the customary Hello World - by rendering a RED screen. To tackle this, one of our resident GPU emulation experts - Rodrigo (aka ReinUsesLisp) - set out to master Vulkan and implement a renderer in yuzu using this API. Thus we quickly realized the need for a way to deliver the same performance to our AMD users, and Vulkan seemed to be the answer! This was mainly due to the low performance on AMD GPUs OpenGL Windows drivers.įor AMD users, this meant that they either had to start using Linux, where the drivers were a little better, or had to buy an Nvidia GPU, and neither of those was an easy choice. How It All Started…īarely a year had passed since the Nintendo Switch launched, but there it was, yuzu - The Nintendo Switch Emulator - already running several games with stellar performance and stunning graphics.īut it came with a caveat to deliver that performance, yuzu exclusively needed an Nvidia GPU among several other hardware requirements. Nvidia appears to encounter the least bugs, but it is still strongly recommended to keep your drivers up to date. We highly recommend using the latest drivers, or beta drivers, as vendors are actively fixing bugs in their Vulkan drivers.
