I upgraded to Windows 10, after starting up the launcher everything is fine,but when i start any of the mod packs they have a long start up time, lagging at the menu screen when i start a map the whole thing is unplayable. Though i also got the windows 10 version of minecraft (basicly pocket edition) it runs "ok". when i start the vanila version from the launcher its still as laggy as one with 180 some mod.
