Minecraft 1.8 Constantly freezes ever 3~7 seconds!! wont let me play in any versions higher than 1.7.10

Minecraft seems to just quit on me in 1.8 if I play whether in singleplayer or multiplayer it freezes my computer every 3~7 seconds. Heres how it works i get on Minecraft 1.8 start the game works perfectly no problems then lets say I join a server everything runs perfectly for a couple of seconds then freezes then runs perfectly no lag no slow player move ment my minecraft just says not responding then unfreezes rhen 3 seconds later it freezes again and repeats in a continuous loop over and over again im stuck playing minecraft 1.7 I think the bug might have something to do with the render increase in 1.8 but im not sure
