GTA V mission 'Caida Libre' crash fix

Okay I heard about it and I feared that it would happen to me also. It did happen but I quickly found the fix for it that worked for me.

When and where 

The problem is very common and it is in all the distribution of GTA V pc i.e. retail and cracked(pirated). Missions like Blitz Play, Caida Libre and many other are affected by it. SO the problem seems to occur in two situations, character switching and use of weapon from the vehicle. SO in my case it was the last character switching to Franklin from Michael after Trevor kidnaps the wife of Martin and brings her to Michael. The character switch is automatic and there's no chance to save the game. So after some experiments I found a working solution.

Solution  

Go to  Settings>Graphics and then change the DirectX Version to 10.
10.1 or 11 doesn't seem to do the job.

So this solved the problem for me in this Caida Libre mission. I think this also fixes the game crash of Blitz Play.
