This seems to be a problem with any AMD processor right now. To fix it find and replace all instance of "SSE_" with "" without the quotes in source/cChunk.cpp
In other words, just delete every instance of "SSE_" without the quotes, but keep the rest of the function name in there, the old noise generation functions are still in the code.
