    We are in the process of receiving more 700 series cards from Nvidia and I will keep you posted with the results.

    I've been using a 770. I have had some issues but I am not sure if they're related to the card or just buggy software.

    1. My "fast" mode is slower than accurate mode (at least based on the fps count on bottom of screen)
    2. Some of my materials did not work (lots of normals issues). Recreating the materials from scratch seemed to work.

    I haven't done any actual benchmarking yet, either, but the 770 does seem slower than my old 580.

    @amoncur - The FPS for Accurate mode and Fast mode are calculated quite differently. On a vehicle file that is 750,000 polys, 14FPS in Accurate mode is really about 3 FPS in Fast mode. You should go by the visual lack of noise, rather than the FPS, to subjectively determine the speed of the rendering, and likewise when the rendering is complete.

    Thus, due to the nature of different modes of raytracing within iray, the FPS in each other rendering modes will not be consistent.

    Try opening the "Bunkspeed Graffiti Benchmark.bif" from the Community to benchmark your 770. I would be interested in seeing your results.

    I see, thanks for the explanation on fps. Regarding the graffiti benchmark, here are my results:

    1920 x 1080 inline: 5:37
    1920 x 1080 background: 5:31 (I did not close Pro, but it was paused)
    960 x 540 realtime fps at 1000 passes: 5.98

    I have a 6-core i7 running at 3.5GHz and 24 GB RAM. Everything was run in hybrid mode.

    How do these compare with 580 or 680 cards?

    Render in the background at 4000x2250@500. We can compare with render times posted previously in this thread.

    Hi amoncur, to have a good base to compare, it would be better to retest (with the graffiti benchmark, for sure) but without CPU, so in GPU mode only, instead of Hybrid

    Rendered in background showing in viewport, jpeg, 4000 x 2250, 500 passes.

    Pretty disappointing. Even Aselert's 480 did better than that!

    Brian, is this about what you expected?

    I'm really sorry for you Amoncur, because on other CUDA rendering app, such as Bunkspeed, the 770 (like the 680) is very very close to the 580...

    Here the last Benchspeed Updated:

    Bunkspeed Graffiti Benchmark 960x540 @ 500 passes

    3x GTX580 = 30s
    2x GTX580 = 42s
    2x M2090 = 53s
    2x GTX680 = 63s, 59s
    2x GTX570 = 61s
    GTX470 + GTX670 = 70s
    2x K20 = 72s
    4000 + C2075 = 72s
    GTX 580 = 80s
    K5000 + GTX660 = 81s
    GTX 570 = 93s
    GTX 480 = 97s
    GTX 680 = 109s
    GTX 470 = 127s
    GTX 670 = 125s
    GTX 660 = 142s
    GTX 560 = 175s
    K5000 = 175s
    5010M = 197s

    Bunkspeed Graffiti Benchmark 4000x2250@500 passes

    3x GTX580 = 7:36
    2x GTX580 = 11:28
    2x M2090 = 12:30
    2x GTX680 = 15:57
    2x K20 = 19:33
    1x GTX570 = 22:57
    1x GT480 = 23:44
    1x GTX770 = 26:19

    Hi Aselert,

    Are you saying that the 770 should be performing better than it did in my benchmark test?
