I am not able to use my video beyond 1080 and it still is framey, if i go to 4k, forget it, it will not play. my pc is got a good upper end processor amd A 8 with radeon HD graphics 1.9 ghz and 6gb of memory. and it is so framey and lags so bad that it just worthless to play videos on. What could it be, junk pc? or some setting i may need to change? Any help sure be appreciated.
