Yes there are profiles for a few Cryengine games, like the Crysis games and Prey. I play War of Rights with this profile.
But you should know that online games that force an anti cheat service (BattlEye, Easy Anti Cheat) will block vorpX, so 3D injection is not possible. I too wish we could play Hunt Showdown. It seems awesome.
One less ideal option is to use the vorpX desktop viewer to play Showdown in your headset. It will not be in 3D, but it may enable mouse based head tracking, and you can size the screen to take up the full field of view of your headset.
