Hello everyone, I have a huge problem with lag and low fps not only in Dota2, but in every single game i played (Hearthstone, GTA V, CS:GO).
I tried so far to reinstall Windows (10, 8.1), to download every single driver update from Dell and AMD sites, to reinstall games, even to rename some files or folders.
I think that the problem might be the AMD GPU. When i tried to see the temperature, it only show for the integrated HD 5500 and for AMD is just a 0.
I have good internet connection and my specs are quite ok (i7 5500U, R7 270 & 8GB Ram).
