A free mod for Witcher 3, by Aeltoth.
AMM patch - asynchronous loading is a small add-on for the AMM patch. This small addon is a huge improvement over the original game, as it allows you to play the game in a completely different way. The most obvious difference is that there are no more freezes after a loading screen. You can still see the loading screen when you first start the game. However, this is not free of charge, as it requires you to make a small change to the core code of the game. It mainly affects the keybinds and the slider in the in-game custom menu.
