Idk why, But everytime i add a new map and launch it, the map has texture tearing. Any fix? 

can you post a screen shot of the "tearing"?

This can be caused by countless reasons. Without me knowing any more information about your situation.
Most common would be.

1: You're running on a laptop?

2: Desktop with no video card / outdated graphics card / outdated or bottle neck drivers.
3: The outdated underpowered card cannot run the 100% graphics setting. which display incorrectly
4: Before you ventured into adding custom maps. Where the Original game's maps displaying correctly for you?
5: Not every custom map is designed as thorough. I.E. even basics like Crouch/Prone/Common animations aren't a thought for the mapper. So graphic/texture changes like Specular maps or any other variables don't exist in game so the intended effects of certain settings technically don't exist in any given map. Creating these problems.


Include more information. About your system specs, video card, operating system. Is it steam/cracked/disc CodWaw.

Maybe you have T4M ?
