DX11/DX12

What is DX and how does it affect gameplay also does it matter which type of the DX using 11 or 12

And does a game automatically change the DX or do you have to manually choose i

API, or Application Program Interface, is a technology that interacts with the applications to allocate computer resources

 

DX12 is the latest version of this API

DX11 is about 2 years old

 

DX11 is the standard, while DX12 was released with Windows 10

 

If you have a NVIDIA 10xx GPU, use DX12 mode if available

 

IF you dont, run DX11 for maximum performance, as the past few gen's are more optimized for 11 than 12

dx12 is still in infancy state and nearly everything that supports both standards runs better in DX11 still.

Direct X is a set of low level APIs that provides a medium for applications to access and manage a computer's hardware. 

 

Right now, DX12 is still very much in early development. In some cases DX12 can result in lower performance than DX11 due to its early development. If a game has support for multiple DX versions, it will typically default to the latest that your hardware supports, with the exception of DX12, which is normally something you'd have to enable by default as not many GPUs fully support DX12 right now.

Actually nvidia cards still run better on dx11, and dx12 in general is a minimal performance gain most of the time

Games are written for specific APIs. Sometimes (especially at a transitional period between versions, like now) games will support multiple APIs and you'll be able to pick between them in the game's menu, but otherwise it's going to use whatever it was coded to use.

 

How much it matters to gameplay depends on the game's developers. DirectX 12 has some technical advantages over 11, but it's just a set of tools. If the developer doesn't choose to put in the time or to implement the right set of features, their implementation of DX12 may be indistinguishable or worse than DX11 mode in the same game. There are many games out now with DX12 modes that are not drastically superior to DX11.

DX, short for DirectX, is a set of application programming interfaces (API) that Microsoft made to aid the development of making games. Contrary to what a lot of people believe, DirectX is a family of API, which handles things like input methods, audio mixing, and most famously, 2D and 3D rendering. When talking about "DX11" or "DX12", people are usually referring to the Direct3D component of DirectX. Which would be Direct3D 11 and Direct3D 12 respectively in this case. But this is more for informational purposes. I'm not going to be a pedantic butthole about it.

 

Anyway, a game using DX11 or DX12 does not matter. It's up to the developer to decide which one they wanted to use based on how they wanted to develop their 3D rendering environment. DX11 is the most popular version right now and is more straight forward of an API to use. DX12 is relatively young, but is not as straight forward to use. However, in the right hands, DX12 can show some impressive results over DX11. Ultimately though, since DX11 or DX12 affects the 3D rendering, the only thing it affects game play wise is performance. But so far most games that support DX12, performance usually is better vs. DX11 from an AMD card than NVIDIA. Not because NVIDIA can't support DX12 (contrary to what many AMD fanboys will tell you), but because the way AMD cards were designed, DX11 makes it harder for developers to make full use out of them.

 

As for games that support both versions, you need to manually select which one you want to use. Games may ask of this before launching. If they let you change this while the game is running, it requires you to restart the game.
