    “It is more efficient to compute the child index of the current node inside the parent node and write the bounds when available. The previous code could load up to 16 AABBs to compute the new ones. The new code also only needs 1/7 of the previously used scratch memory. The new code seems to be around 30% faster (0.5ms) in GOTG on a 6700XT.”

    Shitty missleading clickbait headline though. 0.5ms improvement probably wont translate to 30% more fps with raytracing on RDNA2 cards as the “30% faster on rdna2” in the headline suggest.

        … what?

        Gaming on linux, in general, has been as performant or more performant than gaming on Windows for like… a year now.

        Especially on older hardware, especially for any game that’s 6 months old or older.

        You’d want to actually benchmark this to be accurate as to how much this improves things.

        Basically, this is making a significant section of FSR 30% more efficient. Thats not the same thing as ‘30% more frames’, though it might approach that at lower resolutions or lower game detail settings, while using FSR.

        More or less, I’d guess that this means that if you previously could run a a game at whatever settings with say, performance FSR preset, you could probably now bump it up to balanced, and get roughly the same frames that you used to have to drop an FSR preset level to get… probably only up to 2K / 1440p though.

        But thats entirely just me guessing from having fucked around trying to optimize Cyberpunk 77 on a steam deck, shit’s too complicated for me to fully understand or reason out with a better explanation.

        Uh lets see, also this should theoretically carry forward to RDNA3 as well, as it also makes user of this same thing thag’s been optimized…

        So, that would include more gpus, and, the Steam Machine, which is going to be using and RDNA3 APU.

        Oh right, probably also worth clarifying that this update is not currently out, not just yet. Looks like its slated for February, probably around the time the Steam Machine comes out, would be my guess.

          They are talking about ray tracing, which has been quite underwhelming with RADV compared to Windows.

      It’s for one particular feature I believe rather than overall RT performance, but improved performance is often an accumulation of many small improvements so always great to see nevertheless.

    Sweet. I will ride out my RDNA2 card until it dies. While i’m not a fan of raytracing this will come in handy for the few RT only titles i may be interested in.

    And this is while AMD is trying to abandon support for it and RDNA1 in Windows.

      These improvements are for MESA, by an open source developer for Valve. So not in the AMD driver itself. Older AMD cards do well on linux, because AMD open sourced the driver and incorporated it in the kernel. My AMD experience on linux thus far has been that it just works. Valve is spending a lot of resources on improving the graphics stack on linux.
