I have a Lenovo G570 laptop, which played Minecraft perfectly 1 or 2 months ago. Now, whenever I play the game, I'm faced with freezes, which sometimes crash Unity (with some error message like
intel_do_flush_locks() failed: blah) and graphical glitches (a diagonal twisted segment of the screen occurred once). As I said, I don't know if this is a result of installing OpenCL drivers, a graphics card problem, or a software one.
Thanks in advance, whiskers75
