    What's the video interface you're using?

    Very interesting results, though.

    In your low-res Nexuiz test, both your results are the same (within a margin of error).
    In your high-res Nexuiz test, the CRT framerate is down 62%. Could that have to do with more of the screen being displayable?

    But your OpenArena test shows the inverse -- the CRT framerate is faster by a significant 9 f/s or 13% in low-resolution, faster by 28 f/s or 18% at 1080p, and 27 f/s or 18% at 2560x1600. So the puzzle remains. :/

    The World of Padman and Urban Terror tests are similar -- the CRT got a framerate increase -- but less dramatic.

    The low-res Warsow test is unchanged, but at high-res the new test is 81 f/s or 164% faster.

    Did the tests look all right? (i.e. no serious rendering errors, or hashed garbage?) [I'm assuming you walked away after starting the benchmark, as I'm planning to do next week.]

    What I'm wondering from this is, would the impressive results hold through for a true higher-res display, or are they a result of rendering a subset of either the high resolution or the game view on a lower-resolution monitor?

    But hey -- higher framerates = great!

    So far my 5670 is both surprisingly stable and usable. Of the two GPU hangs I have experienced one was fixed before I had time to report it, and the other was already filed (and a workaround available).

    Try to figure out exactly how the reproduce the hang in Blender and please file bugs, AFAICT there are no Blender related hangs or crashes reported so far.

    I did have a nearly stable setup around February-April. If I remember correctly I used r600g for 2 weeks not shutting down the computer even once. But even during that time I had some stability problems which are hard to reproduce.

    But recently when I tried r600g Xorg(?) hanged just seconds or minutes after opening Blender. I will try again later if it's something reproducible.

    If I see an error dump on screen I usually take a picture of it, but I don't know if such pictures have enough useful information to file a bug report?

    This sounds like something where git bisect should be handy, but it might not be so easy to find a good starting point if that's all you have to go on.

    It's probably better than nothing. You don't have a second machine you cold ssh in from and grab dmesg? (Or running something like "sleep 1m && dmesg > dmesg.txt" before reproducing the hang).

    I already filed a bug. It turned out to be very easy to reproduce (eventually).

    Still for one full hour I thought the problem had already been fixed. But I was wrong. This makes me think it might not be a regression after all. Perhaps it was always there.
