Dungeon Hunter 4 teaches you how to avoid white screens and freezes
Mine has a Tegra CPU, the rest shouldn't be necessary. When I first went in, there were special effects settings, I set them to low at first, but ended up with a white screen and constant crashes. Later I set them to high, and the game ran at the same speed without crashing or showing a white screen. The game is really tricky. Things like enhancements also require an internet connection.
