AH is not listed as a game that supports Pimax Play Foveated rendering. Still, I gave it a try. I turned ground clutter on to add load. FPS held at 90.
No real conformation it worked. I must say the game looked better with it on but looks are so subjective.
I think next time I will crank up enough graphics setting to really drop MY FPS without Pimax Play Foveated rendering. Then turn it on, go back in the game and see what happens.
