The .exe from a.a works fine on a modest GPU, haven't tested yet on higher specs. Thanks again for compiling!
One question:
Any particular reason why the CPU usage jumps and stays to 100% as it runs further and further? This happens with Jean Luc's version too. The temp is normal btw. Maybe is just my machine but I was curious if it's something in the code that makes use of the CPU as well as GPU.
