i think it does affect the ping...i have experienced it in multiple games...for example i have played counter strike without any problems with ping when i had graphic card.however when i change my pc,and i didnt have graphic card,the game was unplayable in the same server,and it was due to ping,which was ultimately due to graphics...so was the case with modern warfare...when i searched for servers,i went into a server that had 30 ping,but in gameply it was nearly double of that,like 70 or 80....so what i have experienced is yes it does affect...
