Directx vs OpenGL (Vulkan) API Which is Better Overall?

Directx vs OpenGL (Vulkan) API Which is Better Overall?:- A gamer plays a game well, but game development appears a tricky thing to them because of so many things in it.

When it comes to development for consoles, developers have a single hardware for a particular brand (PlayStation, Nintendo, Xbox etc): single processor, single graphic card, a particular or same memory, same control input system and other identical hardware components.

In PC, game development face thousand number of problems such as the difference in the hardware configuration of each machine, the difference in graphic card, processor, motherboard, inputs devices, graphic memory etc. which made it a task like climbing a mountain without legs.

This is why, developers move more likely toward gaming console because of there capable hardware, very fewer chances of piracy and programmer and developers have direct access to the internal hardware while programming their software.

This feature of console gives chance to developers to make full use of hardware capabilities. That’s why Direct X and Vulkan API are so important for PC and Android gaming.

Directx vs OpenGL (Vulkan) API Which is Better Overall?

With the same hardware, Windows 7 OpenGL gives 303.4 fps — compared to Windows 7 DirectX gives 270.6 fps only. In short: OpenGL is faster than DirectX.

Clearly, OpenGL is faster API, why is DirectX still the predominant API? It isn’t because of image quality or features: OpenGL 4.0 has all of shaders and tessellation and widgets that DX has. It isn’t because of hardware support: All Nvidia and AMD graphics cards support the latest version of OpenGL along with DirectX.

DirectX is a cleaner API and better documentation is easier to learn. More developers using DirectX = more DirectX games = better driver support. This is a vicious loop that again leads to more DX devs, more DX games, and better DX drivers/tools/documentation.

What is the work of Direct X & OpenGL API?

DirectX, simply, is a software developed by Microsoft that works with PC’s hardware components. Generally, it’s a collection of application programming interface, or API, capable of handling tasks related to rendering 2D and 3D vector graphics, rendering video and playing audio on the Windows platform.

Nvidia says ‘Combining the world’s fastest GPU hardware with a high-quality graphics driver made for the perfect showcase for the next-generation features of Windows 10 and DirectX 12‘.

Open Graphics Library (OpenGL) is a cross-language, cross-platform application programming interface (API) for rendering 2D and 3D vector graphics. The API is typically used to interact with a graphics processing unit (GPU), to achieve hardware-accelerated rendering.

Next generation OpenGL initiative ‘Vulkan‘ is a new low-overhead, cross-platform for 3D graphics and computes API. It was released on 16 February 2016 and with its release, it made so much whisper in the market. It targets high-performance real-time 3D graphics applications such as video games and interactive media across all platforms.

Compared with OpenGL and Direct3D 11 and like Direct3D 12 and Mantle, ‘Vulkan‘ is intended to offer higher performance and more balanced CPU/GPU usage. Other major differences from Direct X 11 and predecessor OpenGL are ‘Vulkan being a considerably lower level API and offering parallel tasking. ‘Vulkan’ also has the ability to render 2D graphics applications, ‘Vulkan’ is actually better distribute work among multiple CPU cores which made it more capable of doing high-performance tasks easily.

Direct x & Vulkan

Most developers are today shifting toward ‘Vulkan’ due to its more compatible dynamic and capable API.

What Direct X & Vulkan Support today?

Direct X API:

‘Direct X 12’ or older actually support mostly every software, Game Engine and Game in the market as of now.

Vulkan API:

As it is not very old API its support is still limited but increasing tremendously over a 2 year period, since ‘Vulkan’ is announced the compatibility of ‘Vulkan’ is increasing very fast and will catch Direct X soon as its predecessor OpenGL.

Game console emulators supported by Vulkan:

  1. Beetle/Mednafen PSX
  2. Dolphin
  3. Libretro port of Mupen64Plus
  4. RPCS3

Game engines supported by Vulkan:

  1. Source 2
  2. Unreal Engine 4
  3. Torque 3D
  4. Quake Engine
  5. Unity Engine
  6. Cry Engine
  7. Unigine
  8. UX3D Engine

Now almost all the games are going to come with both direct x and ‘Vulkan’ support. As both API’s have their own advantages over the hardware. ‘Vulkan will grow much more in Android platform and direct x will continue to capture windows domination.

Directx vs OpenGL (Vulkan) API Which is Better Overall?:- Whatever grows, Direct X & Vulkan, both are going to give us something amazing and powerful. Gaming is going to be incredibly stunning both visually and virtually. Computation of task is going to take a huge jump over time. Sound or audio quality is going to be never like before. System performance is also going to be very high and everything will be going to be amazing. As both Direct X & Vulkan are going to satisfy our gaming needs with there very powerful API’s.
