Hi there! I have an ATI Radeon HD 5570 1GB and I can play many games in high quality. I have ATI catalyst control center to handle my graphics card performance and i can choose if i want to run my games in high performance, optimal performance, Balanced, high quality and optimal quality. However when i choose high or optimal quality i get horrible graphic corruption while playing games. Can I do sth about that or keep playing in balanced? Thanks for reading friends.
