It crashes everytime I load a map :(
Found a fix for crashing :D, open the game, open options, open controls, enable console key, type in console
cl_disablehtmlmotd 1
that disables the message coming up after you click continue, now look for
c:\program files\steam\steamapps\common\counter-Strike Global Offensive\csgo\cfg
and then search for video.txt or video, open the one that says video.txt or video and find a line called
setting.mem_level
next to it is a number, change it to 0, if it is already 0 then I can't help anymore, but that fixed it for me.
