My view on iRay has changed a lot..

After avoiding using iRay for years after my 570GTX met an untimely end while using iRay. .I decided to give it another go, and I am now hooked the big selling point is for what I do I am getting images that before would take upto 30 minutes to render now take from 5 to 10 minutes or less.. The other big thing is hair, some of the hair products I have even with 3Delight shaders will slow 3Delight to a crawl..

On the other hand with iRay I no longer have that problem, iRay goes oh right we have hair no worries and bam done.. Mind you I have CPU/GPU enabled and it really does hike more so with the new version in the 4.12 beta.. In the end I never thought I would ever use iRay and now I am motoring along with making comics with iRay renders..

Here is an image for a comic I am doing it took about 5 minutes to render and then posted through a custom filter in Topaz Studio 2..

    That's the thing a lot of folks overlook; if you are going to do extensive artistic postwork, you can render FAST in Iray because you don't need that precision. And it's a bit more... fluid moving from low quality to high quality, so you can choose where to stop.

    And this is why I am not liking iRay again, and that image was at the default settings, with denoising turned on and that is it.. Though if the scene is dark it renders faster most of the time.. The other is that products like https://www.daz3d.com/audrey-hair-for-genesis-3-female-s and other complex hair products in 3Delight can take forever to render, and yet iRay has no issue, which I find quite interesting..

    That image I posted was a 100% complete render and which was super fast, though as before I darkened the scene by adjusting the shutter and f/stop.. Will be interesting when I get to the lighter interior scenes.. :)

    You should download MSI afterburner and turn the fan on your video card up to 100% before doing Iray renders. Your card will last longer. I would also do about 2min on Iray and stop and use Intel denoiser to remove the fireflies.

    Thank you, I got Afterburner as it has taken off 10+ degrees from the cards GPU.. :)

    Yeah, it's not Nvidia's fault the termal design for the fans are for 3d gaming and iray pushes a gaming graphics card very hard. If you just air cool turning on the fans full blast is the best solution, otherwise I would recommend water cooling with not just a small radiator but a big one. I also use Mcasual denoise script inside daz to denoise iray renders.

    You don't even really need to just run it at full blast the whole time, just have the fan profile set to hit 100% at like 65-70 degrees.

    Yeah have set a custom fan curve, the interesting thing according to GPU-Z, at full load with Afterburner now running I would be lucky to hit 55 degrees C.. Before using Afterburner I would hit 60 to 63 degrees..

    At the moment I sit around about 48 to 52 degrees with full load..

    Damn, that's actually cool. Mine hits 70 sometimes, usually stays in the 60's though. Well, in the summer at least, I don't have AC so it gets hot somedays. Winter it stays a lot cooler.

    I am quitre happy about it as well, and well we are in Winter at the moment here in Australia and since my place has no insulation the ambient temp inside can get quite cold.. Right now it is about 6 degrees at the moment.. :)  Not looking forward to summer going to be another stinker.. :(
