ATI GPU Acceleration Problems
In our last AVIVO Purevideo DXVA HD Acceleration Guide at Benchmark Reviews, we showed how to use your GPU to playback and enhance your videos. While many formats are available thanks to the MPC-Home Cinema player, some users reported some videos which did NOT work with ATI GPUs. While the 90% of the people won´t even play a video which can´t be accelerated with an ATI card, there is a small users percentage which will try and won´t be able to achieve it.
Some examples you won´t be able to reproduce when using DXVA on ATI GPUs are:
- Quantum of Solace Trailer
- AIR OP Theme: Lia - Tori no Uta
- BBC Planet Earth: From Pole to Pole
All these videos can be found at "ahmygoddess" and they also have a great guide on how use DXVA technology. Now, the reason you can´t playback these videos when using your GPU without having black screens or green stuttering is that ATI hasn´t worked out a driver able to reproduce\n high@L5.1 H.264 specs. NVIDIA in the other hand supports \n high@L5.1 with their PureVideo technology.
This guide was meant especially for all those who watch Blu-Ray and some other official video content. This normally falls straight to L4.1. Now, if ATI fails to reproduce specifically\n high@L5.1 h.264 specs then we can´t really do anything but asking ATI do fix that out. Even that, they will think it´s not really a problem for them since they are offering what they promised, and it´s not a problem NVIDIA offers wider support. Even that, ATI should care about the competition.

The way ATI sees this is simple. They actually want the end-users to buy or pay for software which does everything without any difficult setups, and so they also want you to buy your Blu-Ray /HD-DVDs instead of downloading videos form the net. While that works, they will offer no more, and ATI works alright on this section, so they don´t see any factor to change. So, the only thing we can hope is that ATI brings new drivers and update their H.264 specs support up to\n high@L5.1 . Meanwhile, if you are planning to download or watch any content with those specs, you should stick to NVIDIA´s GPUs. Keep in mind that this update could change later, since it is (hopefully) a temporal problem.
Now that we explained this problem we are good to go to some extensive flash testing. So, let´s move to the next page and prepare our GPUs for some DXVA testing with Adobe Flash Player.
