I look forward to the results...

RTX3090 :
ok , did a render of the full scene in HD 1920 x 1080 

24fps
Range :1 to 2600
4K monitor , I set the resolution to 1920 x 1080

Rendertime :  12.35 min

Without Supersampling : 6.08 min

I didn't test 4K yet. ( lazy)  ;-)

Thanks, Bassline.  That makes your 3090 about 40% faster than my Titan, which is a bit disappointing considering my Titan is two generations back.  I would have hoped for at least double the speed (and some of that almost assuredly is due to your i9 versus my i7 -- we can't factor that out, unfortunately, but I would guess it adds at least 10-20% to the speed).

Now there's no question having double the memory is a Good Thing.  Is it worth spending $1500 for, at least for someone like myself?  Doubtful -- I rarely use even 10GB of the 12 that I have.  Cutting my render times down 30% is not cost effective in my particular case (for someone without ANY graphics card the 3090 is certainly looking to be the one to get, though).

BTW, some folks float the theory that iClone will get "redesigned" to take advantage of this architecture.  Don't hold your breath.  They haven't done that for any new NVidia stuff for many years, and it's doubtful they ever will.  They would have to completely redesign their renderer and that ain't gonna happen, I can promise you.  So what we get now is what we will always have -- no one should be foolish enough to buy anything based on "possibilities".

(But, as I say, for someone without ANY decent GPU the 3090 looks to be the winner.  For those with decent ones you need to evaluate the cost versus the memory and somewhat improved performance and decide what works for you).

Thanks Bassline, for the info (at least now I don't have to worry I can't find an 3090 to buy anywhere -- that turns out to be a Good Thing).

you are welcome , Mike :-)

For me  the 24GB Ram are the most important !

This has been an interesting read. Obviously I think we would all be straight out purchasing a 3090 if we could. I bought a GTX 1660 a while back, which I thought at the time looked ok for the money. I now think it's causing be problems since I bought Iray into the mix. Takes like 15mins just to render the active preview. I'm thinking now about buying another card but am looking at possibly the 3070 or at a push the 3080. Just wondered if you guys had any thoughts on those or how best to proceed based on the sort of budget?

One important feature to look for is the amount of VRAM. You need at least 8GB, but more is better. With Iray, when the VRAM is filled up, the renderer switches to CPU and becomes much slower.

I bought a 1080Ti on eBay a few years ago, which has 11 GB. It is adequate, but I hit the limit sometimes, just for regular iClone scenes. I was lucky to get one that was only lightly used and it has been performing fine.

If I were to upgrade, I would get a 3900 because of the 24 GB VRAM. Of course, it is impossible to get one right now. In your case, I would probably get a 3080, which has 10 GB of VRAM.

What are the specs of your system?

Ryzen 7 3800x, 32gb ram, 250gb ssd, 1tb ssd dedicated to iclone. GPU seems to be my issue. Currently have a GTX 1660 6gb card which can't handle iray at all. 

30 series cards are totally unavailable and it seems they will be until next year some time. Best I've found is a used 2080 super with 24month warranty. Even thought about picking up a 1080ti on the cheap for the higher vram then just grab a 3080 next year

I need something to get me going because I'm hardly getting anywhere right now. 

I now have a RTX3090 GPU by buying a PC with it (Alienware Aurora R12), so I thought it would be fun to repeat the benchmark test.

In accordance with how this test has developed, I rendered the full scene in 1920x1080 @24 fps under a few different conditions. The results are as follows:


The full-screen option takes longer, but in my case the quality is comparable with 2x2 super-sampling. I think these are nice results.

As comparison, I did one of the renders with my other system, which has a GTX1080ti;
1920x1080 @24 fps, No SS,  full-screen option disabled  09:35
