well the encoding isn't the issue cause i can playback just fine on my desktop. the issue here is the media playback configuration issue due to faulty software that doesn't work correctly in this case affecting optimus laptops which have a combo of intel + nvidia gpus (in my case a 860m maxwell)

yeah it's not really an acer specific thing, because it seems this 860 issue is also affecting other branded laptops. Or more accurately any laptop solution with a dynamic switching similar to nvidia optimus technology, when it works in conjunction with say intel integrated gpu.

i think even ati is affected somewhat, though i didn't look too much into that. As to what exactly causes this in madvr i can't pin down, i only regurgitate what others mentioned on that.

Also the issue isn't in regards to budget gaming laptop. the issue is software 

Anyway i'll notify madashi on doom9 forum and see if he can work this out. i'll post a fix if it ever comes along
