6 months later, the PROBLEM still remains. Exactly the same issue.
I have installed the latest drivers last week, but this card is still unable to handle hardware decoding, and this from day 1.
Is it a joke?
A REEL and relevent solution is needed.
After more than 6 wait-months, finally a working solution appeared.
m_ray recommended me to completely disinstall and to reinstall the last Crimpson drivers.
So, When I did it, I reinstalled the software bundle Crimpson 17.4.1, (included the driver 17.10 )
At the same time I updated my CODEC pack to LAV 0.69, and to be sure that the player reconized it, I updated MPC-HC to 1.7.11 revision. (All in 64 bit)
Now, it is finally working, using MPC player only.
CPU use only between 0-4% watching a 4K heavy movie in HEVC through a gigabyte ethernet network.
Skipping from part to part of the file is instant. No lag, no artefact. (Which was not the case using software decoding by the cpu with an i5 3570K)
However, with MPC player only. It is not working on VLC yet.
For a totally consistant solution, we should wait more updates here and there, but at least it is useable to built a 4K HCPC.
Hope this will help.
4k was was an issue for me, its h264 interlaced and this problem still remains unfixed. You play the movies fine but if you skip you get awful corruption which can last for a moment or a good ten seconds.
I just think this card is a peice of crap for video use but I need to remain ATI for me 3D stuff, its better at 3D than NVIDA, otherwise I would have drop this crap ages ago.
its a very decent gaming card though for a reasonable price, just wish AMD would remember that at lot of people buy these cards, 480/470/460 for 4k HTPC's, none of them work well.
Guess we;ll just have to hope the next gen fixes this, I think there is a fundamental issue with their silicon though which they may not resolve easily, or perhaps they just dont care about HTPC users which is equally likely.
either way they are actively closing down threads where this problem is mentioned so expect this to get closed at some point.
