Nice trick, but doese't this make u run games at only 40fps constantly? I personaly prefer to lower the details but play at 60fps constantly.
Yes, it's constant 40fps but you will feel like you playing on 60!!! 😉
Besides that, you can also set your game on high settings without any performance loss. However, this will depend on your graphic card. Mine is 880m so there is no problem playing games like the rise of tomb raider, witcher 3.
