Help Galaxy Tab 3 flickering in games

[Bladejmh]

I just got my new tablet and for some reason in any 3d app in which you look around the screen flickers with a triangle taking up half the screen every time I slightly move. It doesnt happen when i look straight forward. This makes it impossible to play any games such as fps games

Have you taken it to the dealer and asked him to run the same game on one of is known-working-properly tabs. It could just be that the game is pushing the video capabilities of the tab beyond what they can do. Or it could be that yours is defective.

It does the same thing on my brothers tablet but have only tried one game that we thought didn't really have good graphics but did the same thing but a game such as asphalt 8 runs perfectly even with all the reflections and such

Should I ask at best buy?
