While using Vibrant Visuals on Xbox series X if any Xbox overlay such as Mic Monitoring, notifications, game/party invites, etc occur; the game will drastically drop in frame rate for about 15-30 seconds after the overlay stops displaying. I was able to replicate this consistently every single time with my frames going from a constant 60 all the way down to 20 or lower. Whether or not this is a problem specifically with xbox or other consoles Iām unsure. The drop in frame rate can be completely avoided by turning off notifications and mic monitoring.
