first, sorry for my english, im from malaysia. I just purchased MSI r9 290 Gaming and installed the driver very carefully. My first game I played on that GPU was dota 2 and the game runs lag after 5-10 mins of played but not very worst. first i tought it was my connection problem. Tthen i started to realise last night when I play fifa 14, the game lags after 5 min of playing. the lag was like scratch DVD. This problem solves by using alt+tab and it smooth for a minute and start to lag again like before. Please help me!
