Ive tried re-installing MC, My computer can run MC at 100-300 fps all the time, Ive allocated 3Gb out of 8Gb of my RAM to minecraft and It doesnt change anything,The server is hosted by MCProHosting, and is hosted in London, where I live. I remember the older versions not having this problem, Ive tried going back to older verison but then my client is too old to connect. If you can help, please do.
Thanks
