Players will get the options of DX12 and Vulkan on the Steam page of PEAK. Check this article out to find out which version to choose.

The moment players try to launch PEAK from their Steam library, they will get the option to choose either DX12 or Vulkan. This is the first decision they will need to make, even before they launch the game, so it is important to get this right. The two APIs can affect your overall gameplay experience even though they both aim to serve the player in the same meaningful way.
The key difference maker in this dilemma will be the hardware of your device. Thus, in order to choose the right option, follow this article.
Should You Choose DX12 or Vulkan for PEAK?

Both DX12 and Vulkan are modern APIs that work towards achieving the same goal. The former is a framework designed by Microsoft for Windows and Xbox gaming, while the latter is open-source and can operate on multiple platforms, including Windows, Android, Linux, and Mac.
Even though the casual gamers won’t be able to tell the difference between the two frameworks, DX12 usually achieves better visuals and higher frame rates in most cases. However, since Microsoft created DX12 with modern Windows and Xbox in mind, you might struggle with this API if you have a PC that falls into the lower end of the hardware spectrum. If that is the case, then Vulkan can be a great alternative for players with weaker devices.
Choosing the Right API for PEAK
The visual aspects of PEAK will largely remain the same in both frameworks. Since the game does not lean towards realistic graphics and physics, most PCs will be able to run it in high settings. Thus, you must utilize the trial-and-error method and run the game on both APIs to see which one is better suited for your setup.
Starting PEAK in DX12 should be fine if you are using a PC with the Windows operating system. However, if you still face frame drops or frequent crashes, you can try switching to Vulkan for a smoother experience.
Alternatively, if you are not using Windows to run PEAK or have a device with old hardware, we recommend launching the game with Vulkan from the get-go. As we mentioned earlier, players won’t notice major visual differences on both APIs, so it is a matter of which frameworks provide the best performance for your particular PC. Once you find the right framework, enable the “Always choose this option on startup” when launching the game.
