If you use an engine like Unity or Unreal, enabling Vulkan in your build for all users will result in the highest performance/longevity. (Note: Proton includes a DirectX-to-Vulkan translation layer. If your game or engine has high-quality DirectX support but no Vulkan support, it's likely that this automated translation layer will exceed the performance of doing a custom Vulkan implementation.) [*][b]Video/Audio Codecs[/b]: We recommend using standalone codecs (eg., VP9 or AV1) rather than codecs that are tied to a specific vendor (eg., WMF). …

[b]Performance[/b] [list] [*][b]2D titles[/b]: your game must run at a minimum 30 fps at 1280x720 during normal play.

You can start off with a basic uploader that just asks the item-maker to select a .zip file and a preview image, or you can build more validation into your submission path. For example, Team Fortress 2 started with just a submission form that asked the item author to pick a .zip file and preview image. But as we iterated on the process, we added a test environment and validation to make sure that the file that was submitted to the Workshop would be easier to integrate into the game. …
