I bought amd r7 250. Recently facing problem couldn't solve it. When I'm playing any games first 3 or 4 minute running well but after that its lagging too much. I updated driver, given windows setup. Done many things but can't solved it. Thats why I recorded a 1 minute video to show you what happening there.
