What is the highest FPS in Minecraft UPDATE 2
7958 FPS.
I used Lunar client and MC 1.8.9
I updated the Nvidea driver to 528.49
I changed the ram ammount to 8 GB
I also ended\stopped all backgrond tasks using task manager
It somehow ran better in fullscreen than in windowed mode
UPDATE: got more FPS by setting the java executable to realtime priority
