    Phoronix: NVIDIA XRender Performance Improved

    Towards the middle of last month, NVIDIA had released the 169.04 Beta Linux Driver. The change-log was quite lengthy and what we had discovered while benchmarking the GeForce 8 series was that there were improvements to be found in this release and it was far more than a simple version bump. One of the reported changes for this driver release was "improved RENDER performance", and out of requests from readers and interest by the Linux desktop community at large, we have conducted XRender benchmarks using render_bench and have the NVIDIA results available today.

    Hmm I'm trying to figure out what applications are really running much faster from xrender boost. Everything feels the same to me...?

    How do I enable the new Xrender feature. I just installed the beta driver. =)

    From what i've seen, the only way to get these results is to set InitialPixmapPlacement to 2, which has the side effect of slowing down almost all gtk apps by a very significant amount. I'm not sure about qt apps, but I would guess it's the same.

    Yeah !!! good news !

    It will be a very very intersting feature for e17 users... because Evas can render by two way, software, or Xrender.

    Great news!

    I've done a bunch of benchmarks on the new beta driver and xrender, and render_bench is the only benchmark that shows these great results without any tweaking. Specifically, setting InitialPixmapPlacement to 2, at least on my 8800 gts.

    A better benchmark of xrender, that shows results closer to what you would get from real applications, is expedite. And yes, evas software rendering is still almost twice as fast as xrender in the overall expedite results.

    Benchmarks are benchmarks, should there be any improvment in real usage? I've had the driver installed since it was released, but I dont think I've honestly noticed any diffrence...

    How'd you read my mind?
