The GPU I have lets me run games at incredible FPS rates. 60 to 1000. I have a GTX 760 Superclocked EVGA model and I used to get 400FPS+ on Minecraft and now I get barely 60. I have examined my PC to see if it was the way its running, also checked if my GPU was running properly and went on other games that require loads of GPU strength such as GTA 4 EFLC, and I got 70 FPS+ max. So I am thinking that the optimization currently in this version is bugged.
Thanks for reading my bug report, and I would love to see it fixed 😉
