Note: For those who are not that tech-savvy, This fix is totally harmless and will not damage your PC, you can simply uninstall the Fix in Control Panel if you do not need it anymore.
This can also be an alternative fix for "OpenGL Version not Supported / Stuck at Safe Mode", "Blurry Graphics / Downscaled Sprites / Sprite Sheet Downscaled", "Unplayable at 1-15FPS"
