    Mesa is known to be slowest in race games (so factor 5 IS representive there), but in quake 3 engine based games it can gain 60% or more in the best case (here and there with some not yet accelerated/optimised features disabled) average performance compared to fglrx.

    Ah, that makes sense! I have WoP installed and it ran very nicely with the Open Source stack. I haven't tried to benchmark it because it is ahuge slow download with the PTS. I may try it overnight. Thanks a lot for the insight! (and I certainly hope Mesa improves in that front )

To get any valuable information out of the mess that is, for example, the GL and XV video performance graphs, they should have been at least two times their size. It'd also be nice to have access to the numeric data in tabular form as an option. More often than not, I'd like to compare numbers instead of trying hard to figure out which shade of $colour represents which cardů
    There are still numbers on the top of the pictures, which show Average, Peak and Low frame rates.

    Here is an old radeon vs. fglrx test I did. All those games a rather playable. Would like to know what you did to get Tremulous running though; it's a slide show even under masa 7.8, and tends to crash.

    It's quite a low level rather than a mid-range! (at its times I mean... nowadays it ain't even worth considering). ok, I bought it as a low budget transition card, but still...
    The 3650 should be about half the performance - it processes 8 pixels per clock vs 16 for the 3850, and does 120 shader ops per clock vs 320 for the 3850. Memory bandwidth is also about half.

    The 3650 vs 3850 numbers seemed about right given the hardware differences.

    It would be nice to know if things have failed miserably or are not sufficiently different to even see a difference, too, you know: you even already have all the data.
    Agreed!

    Not showing the "bad" results boggles my mind.

    You give the impression that everything at least works which is simply is not true.

    Never mind. Got it to work by disabling ST3C compression on driconf.

    When there are many parallel lines like in this graph, I would very much appreciate to have the text associated with each color box in the legend above the graph to also appear as a tag somewhere along each line. Being half color blind does not make for quick and easy identification of which line represent which card...

    Agree on the graphs not been that hot. Having all those thin colored lines close together is hard on the eyes.

    Come on, don't exaggerate, this is just a "friendly shootout" trying to give an idea of what things are like, not a scientific experiment.

    They probably just didn't want to spend time on testing and measuring things that would be so bad as to be useless to just about everybody.

    It's not as if they hid the fact.
