well then maybe you are not playing your games with full video power that you have they might just be using the Intel video and you did not know?, i say this because i have owned 3x laptops over the years that have two video gpu's and all 3, i had to point my games to open, using the better gpu on 70% or more of the games i played. if i did mot do that they opened on the default Intel gpu witch was rubbish lol
Iv been playing online games since 1996 - and i know iv been using the right gfx as noway in hell the internal can run high on everything without preformance issues. Right now im using an Alienware x17 and to be fair, i doubt hardly half the games i play on this can run using the internal gfx, with max resolution. This is the first game since 1996 i had to manuel dedicate the gfx to the game.
Its not that hard to check which gfx are installed on the client, then run a test which card live up to the game demands and change the setting so the game will run using this. Its the gfx test most game run when they start up the first time.
