It's runs in exactly 30-60 FPS (does vertical sync is turned on? Hate it; without vert sync it's about 40 FPS) on 2k with GTX1080. Can you add 3840x2160 option?
Good game. Would be nice to have checkpoints and jump button
you could try to run the Marble Marcher Community Edition on that resolution, that also has better performance and graphics
