I need help bad. i have a HP pavilion (i will attach spec and pictures at the end). I installed the new crimson update. since this i have a constant lag or shudder (freeze then go) in everything. i cant watch films or streams at all. Audio moves as normal and every couple of seconds the picture stops and then plays as normal. The drivers on my graphics cards were updated (15.300.1025.1001). If i do a rollback to microsoft basic display adapter, everything runs fine this lag stops but then i cant change brightness and everything becomes very bright. My restore points don't go back far enough to before update. I email AMD customer help like 3 or 4 days ago, no one answered. I dont know what the last driver i had for graphic card was and i cant find it in legacy drivers. I deleted all the Crimson settings and manager and drivers then re installed to see of that would help and it didnt. Can anyone please help me?.
