My cousin though that it was fun to mess around with my Nvidia control panel, while my settings where perfectly fine. I had between 100 and 300 FPS at minecraft. My FPS is now 30 (Yes, my framerate is at maximum and yes display says i'm using Nvidia) and I tried to change it back and it didn't work. I added both Java programs and I still have 30 FPS. I think I know what the problem is, but I can't fix it. (Sorry that it is in Dutch) http://imgur.com/a/vWJdS As you can see, MC shows up at 'selecteer een aan te passen programma' but when I click on 'add/toevoegen', it disappeared. I think that this is what caused the problem, because before my cousin messed around with my settings, I could add Minecraft. I hope anyone can help me, because i'm not able to solve this problem on my own ;-;.
