Honestly it’s the best performance in Redshift I’ve had and I’ve had zero bugs thus far. But after using it a lot for rendering animation I got used to the speed and now I still want more render power.

r/RedshiftRenderer on Reddit: Optimizing for 4090?
August 30, 2023 -
I just got a new PC built. Was previously using my Macbook Pro M1 Max.
The PC has an i7 11700F, and NVIDIA GeForce RTX 4090.
I am doing some quick test renders in C4D/Redshift, and my task manager shows my GPU utilization hovering around 3%. I see it occasionally jump up to 7% but never higher than 10%.
The CPU usage is around 15%.
This is with the out-of-the-box render settings for Redshift. I bumped up the bucket size to 512.
I am admittedly not very well-versed in render technology. On my Mac, I would see both the CPU and GPU maxing out when rendering.
What am I doing wrong?
EDIT: For those reading, it IS using the GPU - the task manager just wasn't set to display CUDA usage.

February 3, 2023 - Up next in our GPU rendering suite is Redshift from Maxon. Here we don’t see as big of an improvement, with the RTX 4090 only being about 60% faster than the RTX 3090. To a certain extent, this may be a limitation of Redshift’s benchmark.

r/Houdini on Reddit: RTX 4090 faster than 5090 in redshift?

So I just got a 5090 founders today and compared it to a tuf 4090 and idk if I'm missing something but from the tests I've done so far in houdini and redshift, the 4090 beats the 5090 by a decent amount...
5090 was 2:40 for a render vs 2:20 for the 4090, same render, same settings.
And yes I checked and the 5090 does have all its rops. Octane bench results were at 1686 on the 5090
Anyone else experience this?

so I've reached out to Maxon and this is what they told me: "This is a known issue that we have brought to Nvidia's attention, and they are investigating it. The start up time for 50XX series cards is slow, though testing shows that subsequent renders are faster than the first. Please feel free to check our release notes page for any updates on fixes in new releases." I've noticed that it's much faster in karma xpu so which I've been using more now anyways so more reason to fully switch over.

Really in doubt on this one, might need to wait for the benchmarks of the 4090, but maybe I can already start a nice discussion. At the moment I own 2x 3080 TUF Gaming OC's, and in doubt if I should get 2x 3090's second hand on a market place, or just 1x 4090 new.
Prices are dropping for the 3090 with the launch of the 4090, but the power usage of 2x 3090's is way higher than 1x 4090. What are you thoughts?

Just because of Nvlink, 3090 is superior to everything else. You can do power tweaking in any GPU, can even drop 100w playing with undervolting and TDP limit while barely getting hit on performance. So dual 3090s is the route. It will, effectively, give you 4 times the amount of vram You already have (basically 5 times)
