  • Which gfx card with 3D acceleration to buy?

    Hi. I didn't find a forum for gfx cards in general, so hope there is not only ATI fans reading this one

    I'm going to build a computer and I want a good gfx card where 3D accel is working in Linux. (will use the PC for some games in Windows so therefore a good gfx) In my old machine I upgraded from Radeon 7500 to x1650 Pro, but actually it was a downgrade. Everything is more problematic. Watching DVDs are lagging and pixelated. Google earth is extremely slow with the x1650 and the closed source drivers are not working (fglrx gives black screen and system lockup).

    So which is better choice NVIDIA or ATI? My mind was set on a 8800 GT or 9800 GT, but as I see that ATI is now supporting Linux I'm wondering about a Radeon HD 4850. Which cards will give me 3D? Not necessarily today, but sometime before end of the year...

    EDIT: Of course now I saw that there is a gfx card forum and that I'm in the xorg forum. Sorry!

    Well as Nvidia disabled some features in the 8800 GTS 512 maybe get 9800 GTX(+). The G92 chip is really fast, surely faster than 4850.

      No. And it (RV770) will only get faster with every driver update. Even if it *was* slower, it is cheaper.

        I did not say that the 9800 is cheaper, it is just a much better buy.

          I see. So 9800 has 3D in linux?

            I was talking about "The G92 chip is really fast, surely faster than 4850.", not about the driver or anything else. You know, let's wait for tomorrow.

              Yes it does, all the Nvidia cards do.

                I read your post, and it appears that the issue can be resolved by answering a few questions, and providing a little bit of information about the computer...
                1. Which Linux Distribution are you using.
                2. what driver version are you using, and how did you install it.
                3. what is the general system spec ( like is the video card AGP or PCI express )
                4. can you provide a copy of the xorg config file and xorg log file.
                5. Does the system log file specify that a soft lockup occured?

                Note: i believe it'd be better to first try to fix the issue of the system lockups and crashes first, before looking at buying a new parts.

                  1. Ubuntu 8.04 and Debian unstable (switched to Ubuntu just two days ago. Used Debian for 10 years)
                  2. Radeonhd after trying fglrx. fglrx I tried from debian package and ATI package in Debian. In ubuntu I tried restricted fglrx pacakge. No luck
                  3. AGP card (8x) Asus A7V8X-X mobo, 1.7Gb Ram, Corsair 650W PSU (temporarily will go to a new computer), AMD Athlon XP 2400+, LG 1440x900 LCD (is the widescreen a sore point for the driver?)
                  4. xorg.conf I have tried to change from empty to more advanced, but I can try again with fglrx and send it. I used the aticonfig tool. xorg log files I cannot because when fglrx crashes teh system nothing gets written to the log files. It really crashes the machie I have to hit reset button
                  5. I'll check but I dont think anything gets written to system log either.

                  Not buying new part for the old computer. I'll put back the Radeon 7500 if all fails. I'll build a completely new computer because I need more CPU power. But I want to keep my old as a second computer. Currently I have a 166MHz (from 1994!!!) as 2nd computer running debian with wmii and vim. Very nice for not getting distracted by bells and whistles

                    If you are running with an X1650 AGP you may be happiest with the -ati (aka radeon) driver today, assuming that you feel up to building the entire stack - the x driver (-ati), drm, mesa and x server. Ubuntu 8.04 is pretty new but not quite new enough to get full 5xx open source support.

                    I imagine you were using the -ati driver with the 7500 ?

                      Yes. And 7500 outperforms the x1650. It was supposed to be an upgrade not downgrade I'll try the ati driver, but if it is still just crap I'll reinstall the 7500 and get one fan less in the computer.

                      Is there any easy way to do the building in ubuntu?

                        That doesn't sound right. Both cards have 128-bit memory buses, the 1650 has faster clocks, and the 1650 is 4 pipe vs. 2 pipe for the 7500. It's not quite that simple of course (a 7500 can do 3 textures per pipe per clock, for example) but on balance I think the 1650 should still be noticeably faster.

                          Yes, i agree with you on this... i think there is another problem that is not diagnosed.

                          yes, if you go to the wiki pages for installing the driver. and will you please reply to my previous post, because it will be key in speeding up the x1650's performance... the performance problems could be that you are not running the fglrx driver, and other factors also play a role in this.

                            Not hardware-wise, but due to that the driver is bad. When I look at a DVD with x1650 it looks similar to if you look at scaled graphics that is not antialiased. It has large jagged lines on contours. It also lags while playing the DVD. This never happened with my 7500 so it must be driver problems. I tried the xserver-xgl. This solved the antialias problem, but was extremely slow.

                              Here is the syslog when I started the machine with fglrx:

                              http://pastebin.com/m35b9271e

                              Here is xorg.conf

                              http://pastebin.com/m12927fbb

                              No Xorg.0.log file is generated.

                              If I use the ati/radeonhd driver running vlc watching a DVD will result in 50-60% load of Xorg and ~30% load of vlc.

                              Here is syslog when using radeon:

                              http://pastebin.com/m76bbc1c9

                              and Xorg.0.log

                              http://pastebin.com/m583b6d7f

                              and Xorg.0.log for the ati driver:

                              http://pastebin.com/m3a547853

                              Xorg.conf is the same for the radeonhd and ati as with fglrx. Only difference is that I change the driver to radeonhd or ati.
