I have a really nice computer, gtx 770 8 gb of ram and an i7 4770k cpu but i always have problems with minecraft framerate and graphics. I fixed a few of my issues by downloading optifine but now I get this sort of bug very often in which I can see through portions of the map, it tends to happen by fire or lava, or while I am mining. Any sort of insight would be appreciated.
I can see through portions of the map possibly an optifine glitch? Picture included.
