PresentMode isn't configurable (aka Rendy forces vsync)

[Elabajaba]

From what I know, it isn't possible to change the type of PresentMode that Rendy uses without using your own branch and hardcoding the changes.

There are a number of reasons users would want to use something other than FIFO (traditional vsync), some of which might be:

• lower input lag
• benchmarking
• Gsync/Freesync/VRR displays where you're supposed to disable vsync in game and apply it at the driver level
