Well, first of all sorry if this is a common issue.
Anyways, mostly every game I'm trying to run have their textures all messed up. For an example, here's Dota2
Some of the games (like Payday2 and Borderlands 2) that I have this issue can be fixed by ALT+TABBING, and somehow the game works FINE. Dota2 doesn't work, the only way to fix it is to closing and re-opening it over and over until the textures are okay. I seriously have no Idea what's going on.
Some of the games like The Walking Dead does not work at all:
I already set them no the Switchable graphics to High Perfomance, Economy and everything, but didn't worked.
These are my specs:
Laptop Dell Inspiron 15R 5537
Intel Core i7-4500U
Intel HD Graphics 4400 ( http://i.imgur.com/VTqguQ2.png )
Radeon HD 8850M (Catalyst 14.6 Beta, but neither the stable 14.4 works)
Windows 7 Ultimate x64
BIOS Dell Inc. A07, 12/11/2013
I don't know anything else to tell you guys, just that this issue is causing me A LOT of problems. Hope someone can help me.
