Frame drops when using a razer mouse when playing a game from the epic games launcher

Hello , I have had a razer mouse for a long time but recently for an unknown reason I have been getting frame drops when moving my mouse in game , whether I am turning 5 degrees or so on my game can go from 400 frames to 10 frames per second. I have a very powerful pc and the polling rate for it should be fine. THIS PROBLEM ONLY HAPPENS WHEN IM PLAYING A GAME FROM THE EPIC GAMES LAUNCHER. I know its only with razer because I tried to run an epic games game with a corsair dark core pro se and a trust office mouse ( both borrowed from a friend ) and this ran completely fine . I have a razer viper mini and a razer viper v2 pro Pubg battlegrounds and I have a problem with both but even more with the viper mini. I love the feel with the razer mice and want to play my favourite games without unplayable frame drop. Thank you, kind regards.
