I believe staging already includes an updated patch going by this comment in
the source code:

/* Some applications map the whole buffer even if they                      
     * only update a small portion of it. If we pin such a                      
     * buffer into system memory things get very slow as                        
     * we upload the whole buffer even though just parts of                     
     * it changed. Most drivers can handle this case more                       
     * efficient using the OpenGL map functions. Applications                   
     * affected by this problem are Banished and Witcher 3.                     
     */

So yes, performance is still affected with this patch.
