Unfortunately that's a feature of running Linux and you'll encounter the same with a Nvidia card.Originally Posted by Sakkura
ATI/AMD has stopped supporting your card for 3 years now I think. I remember a friend facing problems with his 4870x2 crossfire set up and finding out there were no new drivers for the card at the time.
So good thing the card still works for you, since you are basically on your own now!
out of curiosity, do the latest AMD drivers support hardware accelerated HD video? (known as DXVA) cause they didn't last time I checked. Good for them if they've managed to add that in 5 years after nvidia. ATI were great in 2002, I was their biggest fan, but they fluctuate way too frequently these past few years for my liking.

Yeah. I just had the impression that it was a little worse with AMD than Nvidia, but if the data show otherwise I'm not going to argue.
Latest available driver for the Radeon HD 4850 is 13.1. Named after January 2013. I'm willing to bet performance improvements are going to be extremely slim pickings, but that is to be expected with an old card. Nvidia would be no better in that respect.
Sigh.... Honestly.
oh look, a wikipedia article :)
what the hell does avivo have to do with DXVA? DXVA is not a proprietary standard that you can only get with crappy players like Cyberlink DVD, it's pretty much a requirement if you want to run high bitrate H.264 video decently.ATI Avivo compatible GPUs have lower CPU usage when a player and decoder software that support ATI Avivo is used.
EDIT: ATI support existed for DXVA but was pretty patchy. I remembered my 5870 not being able to play my bluray rips with DXVA. Someone put out a workaround (best AMD support out there, users who got tricked into buying amd cards..) but by then I sold the blasted thing:

I suggest you read on.
I also kind off like how the link you posted was a problem with the codecs the man used and not his video cards, as the problem persisted when the man in question switched to Nvidia.

I dunno, surely if ATI cards are better value, but tend to have a few more driver bugs requiring workarounds, then ATI cards are the enthusiast card, while nVidia cards are for 'noobs' that lack either the knowledge or inclination to bother with that stuff. Alternatively they're both decent enough and there's no much difference.
So AMD stopped updating the drivers 3 years ago, and the OP still runs new games fine? That sounds like massively stable drivers to me. A good thing for sure.
I used nVidia cards for years, then got a 5850 yonks ago and haven't upgraded it until this week. Ended up going ATI again as was best price/performance in my range (7950) and the card worked great straight out of the box, only issue was not having the right power adaptors.
There's so very little in it these days that it makes little difference though.
The poster in that thread was able to run his videos just fine on nvidia but could not configure his card to output audio to an HDTV. I myself own a Philips 1080p LCD and know how to deal with this issue. DXVA on ati however was intrinsically broken on the driver level in 2010.
The other wikipedia article you are linking to describes UVD. Unlike you, I've actually tried to make it work with mkv's - rather than have it described to me from wikipedia! - and it was broken. The screen randomly flashing green, blocky artifacts everywhere, it was a mess. Since you can't experience (or haven't made the effort to try it out yourself) it here's a blog post for you:

Anyway, a HD 4350 used for hardware acceleration for video playback sure is relevant to the discussion of GTX 680 vs. HD 7970.

Nulth of all: UVD IS, for all intents and purposes, DXVA.
First of all: four year old blog post.
Second of all: Edit in the blog post saying that it was fixed in an update.
Third of all: I do actually watch mkvs (doctor Who) with my ati card and it's video accelleration, and it works just fine for me.
fourth: What sakkura said.

badly implemented dxva, right up until 2010 last time i checked
see above. Regardless, nvidia had dxva fully functional in 2006
brilliantly illustrates my original point, AMD is all about "waiting for driver improvements"
well good thing that at this moment amd have their shit together.
it's completely relevant when a driver issue is related. It means that even with a high end AMD card the same problem will occur, as in my case with the 5870.

Which is all that matters. Good day.well good thing that at this moment amd have their shit together.
maybe it does, but I don't like to go with a gpu company which constantly keeps having a string of bad years...
Radeon HD5870, so disappoint!

Before anyone except enthusiasts were using it, and there was already a workaround you posted for them anyway.
String of bad years for features and options most people are never going to run into. Along with not being related to the OP.
For you, AMD has not been for you. For the OP and others, AMD does/would do well as would Nvidia.
