Gsdx Directx 11 Code Can Be

OpenGL supports it and has supported it for ages, all desktop GPUs support it and a few games on the GamecubeWii use it.

What are the reasons behind this I ask this because AMD and Intel have bad OpenGL drivers on Windows and Vulkan is still little adopted.

They want to potentially see a linux port and be able to be easily ported to new future platforms by people that would fork it to others, like RPi.

TLDR: DirectX is locked down to Windows.

Also, it seems some console functions translate easierbetter to opengl than directx, though that may also be due to developers being limited in using the API.

Kinda sucks that you need Nvidia to have good OGL performance.

MH3U (EU Only) will only boot if youre using Nvidia, and Zelda still has issues with performance and artifacts.

My brother let me have his second 1080 since he didnt like SLI and it made a world of a difference compared to my 390X.

Better when the code can be ran on home brew for other hacked systems too 2 Share Report Save level 2 2 years ago Which, while I understand, as someone who likes to have as few devices and cables set out on my Home Theater setup, doesnt really pertain to those looking to emulate sixth gen and beyond and also play modern games.

If you want the most options available to you, Windows generally is the way to go.

Yeah, I know WINE can play most Windows games now AFAIK, but given PCSX2s progress and the devs running into real life problems as far as I understand it, it just makes the other OSes less valuable to me, either because theyre overpriced (Mac), tech thats too new and wont be small and cheap enough to fit for a while, (Raspberry Pi and ARM CPUs) or just plain being obscure to your average office worker (Linux).

But there are a bunch of secondary reasons, especially if you are emulating a 3d era console with a GPU.

OpenGL is the original API and many GPU hardware designers started life working at SGI.

Therefore, early GPUs were heavily influenced by the design of OpenGL and often end up looking closer to OpenGL than DirectX.

Those design decisions continue through to today, and there are often features on GPUs that map better to OpenGL.

There was a time in the late 90s and early 2000s where DirectX was the market leader, but these days Khronos keeps on top of the new GPU features and often releases updates before the corresponding DirectX update comes out.

When a GPU claims it is comparable with the DirectX 11.1 profile, it must support all the features of DirectX 11.1 and absolutely no extra features.

If a GPU is missing just one minor feature of the DirectX 11.2 profile, then all the other features must be disabled too.

If gamedevs are missing a feature they can just not implement that graphical effect.

Emulator Developers often find themselves needing to use a feature, because the original hardware supported that feature and a game uses that feature.

DirectX is often somewhat conservative about which features it exposes to developers.

There are some (often old) hardware features which directx never got around to adding.

But consoles implement and expose those features, so we need to implement them.
