I seem to be having a very misfortune bug at the time of writing this message. Whenever I am in the studio editor, my camera and mouse and very choppy & laggy. However, whenever I playtest within the studio this lagginess disappears completely, then once this playtest has concluded, I return to having a laggy cursor and laggy camera in studio.
I have a AMD GPU, because of this I went into the AMD application and enabled ‘Wait for Vertical Refresh’. After that I relaunched studio and everything was working as expected. Thank you @codeisepic for assisting us into this problem.
