The shaders are too laggy and I can not place blocks or open chests

Please do not mark unreleased versions as affected.
You don't have access to them yet.

Shaders in 1.2? They haven't even come out yet. If it's leggy and you're using blocklauncher then that's why. The game doesn't currently support shaders.
