Hi, all DXVA decoding is broken on all RX cards, i've been trying to get some TECH sites to pickup on this but nobody seems to care that the new RX cards cant hardware decode H264 or H265.

I can't agree with you because with MPC and LAV my RX 460 can handle h.264 and h.265 fine @ 4k in hardware, see few posts above.

I find that hard if not impossible to belive, this is a well documented problem, I think you'll find your CPU is doing all the work for H264 and you probably have one of the driver versions installed that works with H265, my H265 was working initially but H264 has never worked.

The latest drive seems to break both.

If you insist your's is working by all means provide proof as if this is the case people must have faulty cards.

ok, so it turns out that in some cases the RX can hardware decode H264, I was wrong, it seems to have no issues with basline profiles encoded movies at any bitrate but struggles with high profile 4.1 encloded movies at bit rates 30mb/sec or higher. My 5 year old piece of crap 7650 can do this no problem.
