About a week ago I started having these weird FPS bugs when I start up Minecraft. If I join a world or server, I get this awful Frame rate. It isn't even 1 frames per second, it's more like 1 frame per 8 seconds. I have to shutdown my PC sometimes and rarely will it fix the problem, but the problem occurs 90% of the time. I can barely play Minecraft anymore now because these problems don't stop, and if I wait for the FPS to go back to normal it doesn't even work.
