I had luck with turning off gsync in the nvidia drivers. Sometimes turning it down to 60hz fixes games too.

If a monitor is running faster than 60Hz it interferes with the walking animation and the movement becomes jerky and very slow. There is no way to set refresh ingame so I turned it down to 60hz in Nvidia control panel and that fixed it. 

From an accessibility standpoint, could you consider making the blur a toggle or slider in the Settings Menu? It could be called "projector focus". Could be on by default but turned down or off for those who need it, could even turn it up to be silly.
