Will uninstalling and reinstalling a certain game over time slow down it's performance? [closed]
Installing/Uninstalling a game should not affect it's performance.
If your computer is older, I'd suggest pressing CTRL+SHIFT+ESCAPE, that will give you an idea of what is taking your computer ressources and can help you single out the problem that is slowing down your Maplestory experience.
You probably have something running in the background that takes ressources away. I really wonder what tho, because I'm pretty sure MapleStory could run on about anything, including my toaster.
