    I forgot to mention Nvidia's VDPAU. With VDPAU you can watch videos with very little CPU utilization. I think VDPAU was added starting with the 2XX cards. The latest Adobe flash player now uses VDPAU when it's available.

    I just tested VDPAU/flash on an X6 machine that is running High Performance Linpack with 100% CPU utilization on all six cores. The youtube video ran perfectly. Xbmc also supports VDPAU.

    The only way you can offload video with ATI cards under Linux is with Crystal HD add-in cards.

      We don't really about free or proprietary drivers, as long as they work under the conditions described originally (KMS is not much of a priority now, given that the binary drivers are unable to use it).

        I only see that GPU video acceleration will be imporant under very heavy multitasking. Usually the CPU is powerful enough to manage video streams without a serious impact on the system perormance.

          While it's true that a typical CPU today can handle video decode without problems, keep in mind that GPU acceleration can decode video for less power. Power in this sense can be taken two ways. One, the CPU can be pretty underpowered and video decoding still works fine. And two, the overall system power draw from the wall socket will be less (hardware decoding takes less juice than software decoding).

            I can report that I have all the four Humble Bundles and all native games work fine with AMD FLOSS drivers*.

            Doom3, RoE, Quake3, QuakeLive, Quake4, Prey, Penumbra games and Amnesia, and many others also work just fine. Frame rate is slower than with blobs, but it's completely playable.

            *The only exception is Hammerfight, which is too slow, so I'm guessing that it's some SW fallback, but I haven't had time to debug it.

              I also live in colombia and have test ATI/NVIDIA cards in ubuntu (especially in wine) since more or less 2 years for mor information see my blog (stay in spanish):

              http://gamesonwine.blogspot.com/

              I have NVIDIA GF 210 512MB DDR2 (I use low card because if i works good for many people with better cards run much better) and ati drivers suffer compatibility problems while NVIDIA compatibility is very high and install lastest propietary drivers is easy and run very well

                That sounds great, what AMD card are you using? What frame-rates do you get with Doom3 and Quake4? I guess you are using r600g?

                Thanks!

                    I must have missed the headline of the year. Care to point me to how to configure either blob for a KMS framebuffer console?

                      I have an HD4550, which was the slowest r700 card on sale 2 years ago, passively cooled.

                      I haven't measured FPS recently, but Doom3 flew at 1280x960 and high quality settings, with shadows and all. I also managed to run Quake4 at 1080p, and that was clearly unplayable (a few frames per second), but it ran.

                      I finished Prey (modified idTech4) at 1680x1050, and it was fine for the most part (got slow at some parts with many enemies, but very pretty).

                      Keep in mind that this card is the lowest level you can get. If you buy a decent card, it should be faster. This was all with r600g.

                        its pretty easy ^^. If you dont care about the openess of drivers and dont want features like kms, and never want to try alpha or beta versions of distries or try some new kernels which just gut released or are just in release candidate state, and are willing to believe in nvidia that they never let you in a unusable state than go with nvidia. Ahh and if you are happy to somehow modify your distry in the first place (in ubuntu klick on one button and reboot, in other distries maybe type some stuff in the console) so than go with nvidia,


                        But if you dont want all that and you want maybe support from kernel hackers for bugs for your stuff, you should go with amd. (they dont accept bug reports with tainted kernels (with nvidia blob loaded)

                        another question does he really need that cpu power? ^^ Else maybe Llano would be an alternative, but I think because he bought it it makes no sense to change it back, here in germany we can send stuff we bought over the internet back without giving a reason till 2 weeks after we got it

                          Do you think it is reasonable to completely forget about nouveau? Usually somebody would use the nvidia binary for best performance, but basically if you are an oss fan you can certainly use nouveau - and those drivers are not the slowest if the gpu clock is set to highest speed, maybe even better than radeon. Thats nothing thats only for amd cards, there you are just forced for much more cards to use oss drivers, you dont have got the choice anymore. Usually i would recommend to buy the cheapest card possible if you want to use oss drivers but well if you only play games with win maybe something faster would be also a good idea.

                            I don't know about the performance features and stability of the nouvou drivers and which cards are supported and which not, but I would be very sad if they would be better or even nearly at the same state the radeon drivers are.

                            Because the opensource community would basicly say, we piss on companys that give us free specs and drivers and help the concurent company that blocks free drivers to sell more cards. Each company who would give theyr specs and drivers out for free would be stupid because they just suffer from them.

                            So hopefully this devs at least not try to make them as good as the radeon drivers or they really do damage for linux on the long run. If somebody would ask me I would boykott nvidia with drivers, so they who like the blobs and dont care buy nvidia cards, the people who do care and dont want the practical limitations of this development process go for ati.

                            If only blobs are good and no problem and people dont care about it, good, but why making then against of the will of nvidia for them free drivers so that they sell more grafic cards.


                            Sorry for the bad english, but I think its understandable enough? ^^

                              Well there are no open specs, thats correct. But as reverse engineered driver it is really good. Maybe you should try it before you complain so much.

                                So but my basic statement is true, if you care for openess or freedom or stuff go for amd if you dont care go for nvidia.

                                I am thankful, and not selfish, so I am very thankful for amd for giving support to linux and I donīt reward companys that are unsocial.

                                So if you say the nouvou drivers are good, so I have to believe you but you did not say is it better or not that good like the radeon drivers?

                                I surely donīt buy a nvidia card support this company just to look at this nouvou driver.
