Vulkan bug on some GameCube games?

[ganon]

So I thought vulkan was supposed to be better than opengl but it lags quite a bit with some GameCube games like mario sunshine and windwaker. Is there some kind of bug or its game specific because Fzero GX performs better with vulkan.

It's most likely because the driver support for Vulkan is less mature. It is also natural for it to vary a bit between different games.

I did notice Fzero GX and Melee work better with vulkan, both of which are 60fps games.

In my xiaomi mi6 the vast majority of games run with better fps in vulkan
