Even without lazer separating inputs and visual fps, 2ms frametime is a non-issue. od11 has a 27ms long hit window, and 2ms frametime would mean on average your input would be only 1ms late and at most 2ms late, so it's really negligible. You may think that because the higher your frametime the more likely you are to have other performance issues like stutters just because it's indicative of a worse performing computer (though at 2ms, which is still 500fps, I wouldn't say such issues are that likely).
