After some investigation, [epicboy](https://github.com/ameerj) found that the reason for the bug is an over-optimization introduced by the new drivers (an optimization for one scenario results in issues for another).
[A small change in behaviour solves the issue for good](https://github.com/yuzu-emu/yuzu/pull/7724).
You can find more technical information in the pull request.
Users playing `Hyrule Warriors: Age of Calamity` or `Luigi’s Mansion 3` should stick to the 47X.XX series of drivers, as any version newer than that will have several rendering issues.
We’re investigating the cause.

epicboy [adds support in yuzu for unsigned 2x32-bit atomic operations](https://github.com/yuzu-emu/yuzu/pull/7800) as that’s the fallback option such drivers use.
With this change, the game boots in Intel GPUs running Vulkan.
What was originally a mistake on our part, turned out to be a simple fix for uncountable games.
While this was recently changed in the Linux AMDVLK drivers, AMD Windows drivers still need to be told what `Execution Mode` will be in use next.
AMD had a longstanding issue with `Transform Feedback` on both their official Windows and Linux drivers, causing rendering issues in uncountable games.
While this was recently solved in the Linux AMDVLK drivers, AMD Windows drivers still need to be told which `Execution Mode` will be in use next.
[Explicitly stating to use Xfb](https://github.com/yuzu-emu/yuzu/pull/7799) `Execution Mode` before starting to use Transform Feedback solves all issues related to it on AMD Windows Vulkan drivers, not only benefiting `Pokémon Legends: Arceus`, but also games like `Xenoblade Chronicles 2`, `Xenoblade Chronicles Definitive Edition`, `Hellblade: Senua's Sacrifice`, `Donkey Kong Country: Tropical Freeze`, `POKKÉN TOURNAMENT DX`, and many others.

The bad news is that this is a problem with the `Buffer Cache`, and fixing it will take considerable time.
The good news is that [Blinkhawk](https://github.com/FernandoS27), with some help from epicboy too, managed a temporary workaround to avoid this problem while a permanent solution starts taking shape.
[Flushing the buffer before writing](https://github.com/yuzu-emu/yuzu/pull/7805) saves us from polygon hell, at a small performance cost.
