Mouse issues after upgrading to Mac Sierra

Experiencing a lagging/sporadic mouse after upgrading to Sierra. I have read other posts regarding Logitech and Razer mouse problems with the new Mac upgrade. I had been using a Logitech G303 when the problems started happening. I thought if I bought a new mouse the problem would fix, so i bought a Corsair M65 and the sporadic movements still occur. These annoyances only occur in LoL. The mouses work fine in any other game/ browsing the web. Anyone know a solution to this?
