A few days ago I wanted a FPS boost, at the time I was getting 20-60 fps, which I had ben playing with for 9 years. I got opdefine, put the settings to the highest FPS, and was very happy! 120-230 fps! The next day I was exited to play with 230 fps when I noticed to my dismay I was back to 20-60 FPS! I looked back at my settings but they were unchanged from the FPS boosting settings, they were the same. I have tried everything, all the way to deleting everything to do with minecraft on my computer and reinstalling several times, I even tried a factory reset several times. Nothing. Ive ben trying to fix this for 3 days.
If you have any questions, requests for more in depth info/proof on the problem, or solutions I am all ears. Because Im desperate.
