As a ROBLOX developer, it is currently too hard to make games with particles and textures in quantity because of the graphic settings the Xbox One is currently defaulted at (10). There should be a setting to turn down the graphics level just like on PC or give developers the ability to set the graphics level at which the place is at. Lag is a main issue for Xbox One as I’ve seen it as a complaint by many players/developers on the platform and have one myself.
One big issue is that just loading into games causes a lag spike for 5 seconds. Very annoying.
