#Super smash bros legacy xp 2.0 directx 12 drivers
AMD official drivers for current modern hardware is the closed-source catalyst (their own different stack).

Intel official opensource driver don't use it (but there are attempts by 3rd parties to make gallium drivers) So you're probably getting near native spead when running windows software on linux through wine, instead of slow down due to the opengl translation layer of wine. For older Radeon hardware, the opensource driver is what AMD recommand, they are stable enough, fast enough, and still maintained. It's quick to develop, specially because Gallium has already support for most of the needed functionnality to provide Direct3D 9 (unlike an older Direct3D 10/11 driver which were attempted earlier). It's much faster that way, because we directly call hardware function, instead of having to map to concept from another API (openGL) which doesn't work the same way. It doesn't need to go throug a complex intermediate translation step. Now this Gallium stack is much more direct, it receives Direct3D calls and directly execute them using the low-level functionnality exposed by a hardware layer. Even more so because OpenGL and DX3D do not function in the same way, so implementing some stuff requires quite a complicated translation. It works, but it's difficult, and it's slow: this translation layer comes at a cost.

Up until now, the way 3D worked for Windows software running under Wine, is that wine has a layer that intercepts all DX3D calls and retranslate them into OpenGL then sends those to the running OS (to Linux or Mac OS X). That's what is being done regarding DX3D9 in this news. No need to write a full Direct3D stack for each single available hardware, just write a generic stack for Gallium.
And bam! you get automagically support for any hardware whose low-level provide enough functionnality. If you want an additionnal API, you only develop a state-tracker, the high level part of Gallium which speaks the API. (That's how most of the newer opensource drivers, like all the new GPU for ARM SoC are implemented or are going to be implemented) No need to write a complete new OpenGL driver from scratch. And bam! you get automagically support for any API for which you provide the necessary functionnality. If a new hardware comes, you only develop a new low-level drivers exposing the functionnality of this new GPU. This make the whole development much faster and help code reuse. on the other side you have "state tracker" high-level interfaces speaking the various API (OpenGL, OpenCL, etc.) on one side you have low-level drivers handling the hardware (or the CPU in the case of the LLVMpipe software driver) and exposing the basic GPU functionnality. The idea of the Gallium3D modular design: the modern Gallium3D Mesa is a modular architecture for 3D API (that's what is used by modern opensrouce drivers, like the reverse engineered Nouveau for Nvidia, or the AMD-sponsored Radeon driver). the old classic mesa is just a plain big monolith exposing OpenGL (that's what Intel provide for their official opensource drivers. (- the closed sourc drivers uses their own sauce instead)
Mesa is the opensource 3d graphics driver used on Linux for opensource drivers. Yup, indeed, it's just a small quick news on phoronix. It seems to be one of those articles written for people who already follow the subject, rather than casual readers.
