Re: No Graphics API
#2This is a fantastic article that demonstrates how many parts of vulkan and DX12 are no longer needed.
I hope the IHVs have a look at it because current DX12 seems semi abandoned, with it not supporting buffer pointers even when every gpu made on the last 10 (or more!) years can do pointers just fine, and while Vulkan doesnt do a 2.0 release that cleans things, so it carries a lot of baggage, and specially, tons of drivers that dont implement the extensions that really improve things.
If this api existed, you could emulate openGL on top of this faster than current opengl to vulkan layers, and something like SDL3 gpu would get a 3x/4x boost too.

#3This looks very similar to the SDL3 GPU API and other RHI libraries that have been created at first glance.

#5the article talks a lot about PSOs but never defines the term
"Pipeline State Objects" (immutable state objects which define most of the rendering state needed for a draw/dispatch call). Tbf, it's a very common term in rendering since around 2015 when the modern 3D APIs showed up.

PSOs are Pipeline State Objects, they encapsulate the entire state of the rendering pipeline.

#7I wonder why M$ stopped putting out new Direct X? Direct X Ultimate or 12.1 or 12.2 is largely the same as Direct X 12.
Or has the use of Middleware like Unreal Engine largely made them irrelevant? Or should EPIC put out a new Graphics API proposal?

Isn't this all because PCI resizable BAR is not required to run any GPU besides Intel Arc? As in, maybe it's mostly down to Microsoft/Intel mandating reBAR in UEFI so we can start using stuff like bindless textures without thousands of support tickets and negative reviews.
I think this puts a floor on supported hardware though, like Nvidia 30xx and Radeon 5xxx. And of course motherboard support is a crapshoot until 2020 or so.

#10I miss Mantle. It had its quirks but you felt as if you were literally programming hardware using a pretty straight forward API. The most fun I’ve had programming was for the Xbox 360.
