Does it still crash if you lower your video settings?

Good idea, so I played around with the settings, trying different combinations.. If I set shadow quality and shader detail on low, no crashes. Hopefully this gives you clues how to adjust the map or optimise it more? :)

Still not sure what could be causing it, but I'm certain the shadows have nothing to do with it, and unsure what could potentially be so shader-expensive to crash the game either.

I also get crashes only on this map. It seems to always happen near the non-opening blast door just past the opening one near CT spawn. When there is a firefight there or in the small vent shaft that is located above it I always seem to crash. The past few times I've noted that it usually happens a second or so after I get a kill in this area.

and turning down your shader/shadow settings fixes the problem?

Ok, the shader quality doesnt seem to matter. But going from high to medium shadow fixes the problem.

I am able to cause the crash by shooting this bank of computers by the blast door:

Just spawing as CT and unloading a few mags of pistol ammo into while running back and forth does it every time.

Actually it crashed again,but ...

[Go on your Counter Strike Global Offensive folder and go to the cfg folder(specifically: C:\Program Files\Steam\steamapps\common\Counter Strike Global Offensive\csgo\cfg) and search for the video.txt file. When there search for a "settings.mem_level" thingie. On it's right should be a number, try setting it to 0. It stopped all the crashes between map loads and skin related bugs.

.... You know what i mean.

I've read of setting it to 1, 2, or 3 also. who knows what that actually adjusts? do you crash on a map de_Crossfire too?

No after my edit i never crashed offline,online or between changing maps.
Yes i have de_Crossfire but I never crashed on it even before.I used to crash only on Museum and Thunder.

Setting it to 0 seems perfect.
