This time, yuzu was not following the official Vulkan specification correctly, leading to overlapping information for textures and buffers on Nvidia graphics cards.
`bufferImageGranularity` specifies the size in bytes at which textures and buffers can be aligned.
AMD and Intel GPUs allow for pretty precise values of 1 or 64 bytes depending on the hardware, but Nvidia on the other hand is hard limited to a 1024 byte block.

There was a bug that made Mario's moustache appear to be light-brown (instead of the classical dark shade we are used to seeing) when using an Intel GPU with the Vulkan API.

For example, `Mario Kart 8 Deluxe` needs holding L + R + presing the left analog trigger (L3) in the main menu to be able to create or join a LAN room.

By lying to the kernel and informing that performance is always good, the emulator avoids unnecessary destruction and reconstruction of textures, saving both performance and VRAM.
As an added benefit, some games use this *totally-not-adulterated* information to constantly render at their highest supported resolution.
For both these reasons we recommend users to keep this option always enabled, as no regressions have been found for using it, and the stability benefits on some particular titles

# Input improvements
german77 has a few input changes done this month.
german77 implemented a few input changes this month.
First of all, when mapping and moving an analog stick, the previous implementation used to only show a blue dot representing the relative position of the analog stick.
Now [a new green dot is added](https://github.com/yuzu-emu/yuzu/pull/6815), which represents the emulated position of the stick, considering range and dead zones values.
Useful to know if the stick actually reaches the whole input range.
