LEft 4 Dead

Guys please advice LEft 4 dead is crashing frequently after 10 to 15 minutes, other games are working fine.

I am using skullptura version, I try to re-install it but the problem does not resolved.

Does anyone faces the same issue

Set multi-core rendering to 'off' and page pool to 'low' in game video options, and it won't crash.

problem still exist but now it came less.
