Hi! When 1.9 came out I couldn't play on 1.9, but I've put VSync and VBO's on and now it works, however Optifine 1.9 came out and I downloaded it to have a better performance while playing on cubecraft but now it crashes again (Only with optifine). I need help, I really need to play with optifine, it helps a lot. Thanks. P.S: If you need I can post the crash report.
