It is obvius it needs a button to compile the shaders on demand because all my sistem is blocked, for example it started to build shader then the autosave started then nothing, It just crashed. I think my system is quite good it’s a dell inspiron core I7 with 6 Gb in Ram and ATI 2048 Mb Video Card Laptop, Games like Skyrim works with full graphic details without problem, Compiling a software with 7000 lines of code is not a problem and here it crashes on some asset shaders
