Matteo De Vellis :
I want to play Warframe on my laptop which has a GT 740m and Warframe says that the GPU isn't supported. I have the lastest direct X updates and the lastest GPU drivers from Geforce experience
Explain what
you are saying vs what he posted that the game is telling him. I am not the one saying it. The game said it. So no matter what WE say, the game is not going to change.
I'm going to suggest that you have a nice long chat with his game so that you can convince it that it is wrong, and will allow him to use it to play the game. Once you have completed that, I'll send the next guy that wants to use a GT 740M with that game to you too.
