Thanks to Linux’s mesa drivers progress, we recently modified our minimum graphics requirements.
|
||||
|
||||
[yuzu now requires OpenGL 4.6](https://github.com/yuzu-emu/yuzu/pull/5888), any compatible hardware achieves this with its latest GPU drivers installed. Even old Fermi or GCN1.0 series products.
|
||||
Laptop users, like desktop users, should visit the GPU’s manufacturer site ([AMD](https://www.amd.com/en/support), [Intel](https://downloadcenter.intel.com/product/80939/Graphics), [Nvidia](https://www.nvidia.com/en-us/geforce/drivers/) instead of the vendor’s site of the laptop (HP, Lenovo, Asus, etc.), as it will provide compatible and much more updated drivers. Thanks [Morph](https://github.com/Morph1984) for the change!

On the flip side, we still keep our requirement of Vulkan 1.1, but as stated in previous articles, [Rodrigo](https://github.com/ReinUsesLisp) made `VK_EXT_robustness2` [a hard requirement now.](https://github.com/yuzu-emu/yuzu/pull/5917)

On the flip side, while the requirement of Vulkan 1.1 hasn't changed, as stated in previous articles, [Rodrigo](https://github.com/ReinUsesLisp) made `VK_EXT_robustness2` [a hard requirement now.](https://github.com/yuzu-emu/yuzu/pull/5917)
|
||||
This means that updated drivers are critical now, as lacking this extension will stop yuzu from booting games while on Vulkan.
|
||||
AMD users still require to install the latest `Optional` driver version to get support for robustness2. At the time of writing, the latest version is 21.2.3, but yuzu will work with drivers as old as 20.12.1.

## General bug fixes and improvements

`Pokémon Sword and Shield` players can enjoy one less reason to crash the game.
|
||||
Boss [bunnei](https://github.com/bunnei) [fixed LDN initialization,](https://github.com/yuzu-emu/yuzu/pull/5920) eliminating the crash that occurred if the player pressed `Y` during gameplay, activating online services that yuzu lacks by mistake.

An error window will still pop up, but emulation will continue.

Under certain conditions, the `WebApplet` would crash yuzu when opening, for example, the Action Guide in `Super Mario Odyssey`. [aleasto](https://github.com/aleasto) managed to solve this by [fixing an out of bounds read.](https://github.com/yuzu-emu/yuzu/pull/5878)

A common annoyance that affected new users was asking for placing the derivation keys in the correct `keys` folder, a folder that had to be manually created until now.

Thanks to [Morph,](https://github.com/Morph1984) now there is an empty `keys` folder created by default as part of the installation process of yuzu, ready to be populated by the user’s own Switch’s keys.

First, Vulkan needed some [corrected offsets](https://github.com/yuzu-emu/yuzu/pull/5936) for `TexelFetch` and `TextureGather`, types of texture instructions.

A similar change [was needed for OpenGL.](https://github.com/yuzu-emu/yuzu/pull/5980) this work also includes better handling of `signed atomics`, improving precision. Thanks to [Ryujinx](https://github.com/Ryujinx/Ryujinx) for helping here.

[Rodrigo](https://github.com/ReinUsesLisp) [fixed a bug in Vulkan’s stream buffer,](https://github.com/yuzu-emu/yuzu/pull/5919) improving performance and reducing VRAM use, while also making better use of the dedicated VRAM, instead of falling back to shared VRAM, better known as just system RAM.

||||
|

By [using dirty flags](https://github.com/yuzu-emu/yuzu/pull/5923), [Rodrigo](https://github.com/ReinUsesLisp) also managed another slim but measurable Vulkan performance bump. Reducing draw calls always helps!

|
||||

|
||||
|
||||
After a lot of time of experimentation, [Rodrigo](https://github.com/ReinUsesLisp) [reduced the size of Vulkan’s command pool](https://github.com/yuzu-emu/yuzu/pull/5989), from 4096 to just 4.
|
||||
This makes the driver assign less memory for command buffers, saving a considerable amount of system RAM.
|
||||
|
||||
For example, in `Pokèmon Sword/Shield`, Vulkan’s use of system RAM goes from 707MB, to just 2MB.
|
||||
|
||||
To end the day, [Rodrigo](https://github.com/ReinUsesLisp) fixed a regression introduced by the `Buffer Cache Rewrite`. Some games benefit from skipping the cache, but others lose performance. For example `Animal Crossing: New Horizons` was severely affected in Vulkan.

Some games benefit from skipping the cache, but others lose performance. `Animal Crossing: New Horizons` was an example severely affected in Vulkan.
|

By [implementing a way to heuristically decide when to skip the cache,](https://github.com/yuzu-emu/yuzu/pull/6021) performance was not only restored, but also increased.

## Input improvements
|
||||
|
||||
First and foremost, [german77](https://github.com/german77) finished implementing [native Gamecube controller support!](https://github.com/yuzu-emu/yuzu/pull/4940)
|
||||
With this change games will now detect GC controllers as such, instead of emulated Pro Controllers, for example.
|
||||
Planned for the future is support for analog triggers, right now they are mapped as buttons, but they will be handled correctly in coming changes.

|

Another new feature [german77](https://github.com/german77) added is [mouse panning.](https://github.com/yuzu-emu/yuzu/pull/5869)
|
||||
This allows to set the mouse as an analog stick, allowing very comfortable gameplay on games that for example use the right analog stick as camera control.

[Morph](https://github.com/Morph1984) [implemented the Finalize request](https://github.com/yuzu-emu/yuzu/pull/5908) on the inline keyboard emulation, allowing it to exit in a stable, graceful way instead of looping indefinitely.
