I watched Gerry in a video and his preview window updated to 500 (whatever that means) in 1 second, and mine would take about 5 minutes to do the same thing. CC 3 also seems slower opening stuff than CC 2.3. I only have 2 Gig GPU (NVidia GTX 950), but the IRay is is so slow it is not useable. So I just saved $179 once I get my refund, I can use that towards a new graphics card (Only #1,021 to go + $100 tax).

As you proved, your graphics card is way underpowered for ray tracing, and is actually well below what most of use would suggest for iClone.
But even with a very good card, ray tracing rendering will be much slower than the iClone native renderer.

I can report that I've obtained some promising results from my initial testing of iRay. I've achieved acceptable quality renders at 150 iterations even without denoising. On my ordinary GTX-1070 card, the render times have been anywhere between 40 seconds and 1m 30 (depending on the scene). This is for a 1920 x 1080 frame and using the default setting of 16 Max GI Bounces. I'm cautiously optimistic regarding short time animation. This frame (150 iterations), took 52 seconds. It's by no means 'perfect' - but I'm happy with this quality for animation.... 75% of original size (was 670x19) - Click to enlargeThe iClone 'native renderer' below: 75% of original size (was 670x19) - Click to enlarge75% of original size (was 670x19) - Click to enlarge75% of original size (was 670x19) - Click to enlarge75% of original size (was 670x19) - Click to enlargeThis last pic is hugely magnified, since it's merely cropped out of a 1080p frame. All images are cropped from the same *first* frame above. The left eye on this last pic shows iRay 'life' and the 'speckled look' is simply due to the render being terminated at just 150 iterations .....

I was just referring the IRay preview window in CC 3. It just seems strange results would be 1 second vs several minutes even with 5 times the GPU.

Data Juggler (9/29/2018) I was just referring the IRay preview window in CC 3.

No, I am comparing my IRay Preview time, versus Gerry's in this video: https://www.youtube.com/watch?v=QHShVA2zBzM
Every time he moves, the preview window refreshes instantly. I am not using the same character, but it takes forever for me, and his are instant or near enough.

Hi, i tested my rendering times with different setting Iray background render, same scene, same Max Gi bounces 16, De Noice on, 150 samples 4CPU+1070+1070 = 42 sek 1070 only = 52 sek 1080 only = 51 sek 1070+1080 = 41 sek p/s Iray preview is so slow that i cant use it, very strange. | |

I think the initialization of Iray rendern takes time, so it takes more time to compare the times. When I tested the same scene with 1000 samples iterations I got the time 128 seconds. 128 sec / 1000 = 0.12 sec per sample compared to 42 sec / 150 = 0.28 sec per sample. There will also be different times depending on how much the image is zoomed in or zoomed out. The question is whether an initialization for each new rendering is necessary for an animation or not?

Good points Brand ... Yeah - I've found that zooming in to a closer shot of 'actual mesh' can x3 the render time. I've also just discovered I can get away with even lower iterations - I've experimented with 30 - and it CAN be OK. (probably not facial Close Ups) Another trick - render at UHD (3940 x 2160) - with NO de-noise and at 30 iterations. Then resize to 1080p (this being for animation / movies) .... (of course we can only test single frames at the moment). I'm surprised that the 1080 didn't do better (compared to the 1070 in your tests) - I actually thought there'd be a bigger difference .... And yeah - I'm getting just under 10 seconds for 'loading' time. Don't know about you, but I find the de-noiser a bit 'savage' - I'm wondering if there's a separate adjustment other than just on or off.... On close-ups of skin textures it can totally smear out the pores in *some* parts but then not on other areas, making it a bit 'blotchy'. I guess it just works to a 'threshold' value. If there's no fine adjust on the de-noise - I don't think I'll use it to be honest. UHD doesn't take that much longer - and then resizing to 1080p is sort of a de-noiser in itself and it leaves a nice amount of texture (without smearing it out) ....

Yes, it is strange that 1080 is not so much faster than 1070 and that it does not increase more together. Have now found something very interesting about the fact that iray preview goes much faster than background render on my computer! I have a 40 inch 4K screen with 3840x2160 resolution + 2 with 1920x1080 resolution. I have now discovered that if I move Character Creator 3 to a lower resolution screen, the rendering progresses much faster, so screen resolution affects the time of preview but not on background render .. p / s Seeing that they are using 2x1080 in Gerry's video, maybe they are 1080 Ti? Have used Iray denoice in DazStudio 4.11 and the sharpening increases if you run more samples, think it's the same here. | | | | | | | | |
