So guys, here is the problem. I built a new PC recently, it is quite decent i think and it is supposed to run pc games smoothly. But there seems to be an issue with my GPU, since I get really bad graphics from it - it is Sapphire Radeon R7 250. It constantly blurs everything around the edges of objects in most games I play, and sometimes creates some textures in certain elements from the games, like walls, floors etc. and these textures move along with me moving my camera. This is pretty disturbing and I would be really thankful if you can find a solution to this problem.
