Slow Render time Rtx 3090 i9 96gbs of ram

Hello everyone. Im a bit frustrated at how long my animation renders are taking. If anyone has any advice or tips that can help speed up my render times that would be greatly appreciated. Atp Im about ready to give up on Daz as far as animation goes. It took over 8 hours to render about 40 frames in a sequence animation. Its taking about 15 min to render 1 frame. Am i doing something wrong?
Specs: RTX 3090
i9-7900X CPU @ 3.30GHz 3.30 GHz
96gbs of ram
Ive attached a frame from the animation for reference its 2000x2000

Rendering is relatively slow - that's why films use big render farms with multiple machines grinding through frames. Ten minutes for a 2,000 pixel squre image does not sound unreasonable - simplifying materials might help, as might avoid shadowy areas like the back of the arcade in your example.
Reduce resolution, change your settings, add more light.
Reduce the image size and limit the number of samples.
I have rendered animations at 800x600px and a scene with one G8 character and architecture takes less than a minute to render per frame (max 500 samples)
Edit: Im using a 3060 12GB
Since Nvidia worked on accelerating pre-calculated renders, tons of people (born after year 2000 usually) want their images in 5 seconds....
Not at all. You're just expecting something that does not exist (yet). When anyone uses path or ray tracers, renders take time. A lot of time. Just gotta live with that in mind. Pixar/Disney (huge size images of course) work with a computer farm of about 24,000 CPU cores and it takes 24 hours to render 1 frame.
So don't complain about 15 minutes with just 1 computer. No matter how many CPU/GPU cores you have, 15 minutes is VERY short. Very very very short. Someone with a 2070 Super would probably wait 2 hours for the same result. So be : happy. What you're experiencing is all very normal.
If you want speed : stop pre-calculated renders and work for the video game industry.
Thanks for the feedback everyone. At least now i know it isnt a user error
Slow in comparrison to what?
"Your expectations" doesn't really help us understand what you mean.
You have a lot of light and shadow; the image is well cleaned, which I'm guessing you have thrown horse-power at. Your scene looks like it was designed to be a hog for resources. :D
There is a lot of glossy materials, which also take longer.
Reduce the converge ration, perhaps the quality (depending on what you have) even reduce the update interval from 5 seconds to a couple of minutes.
Rendering is intensive.
A good gaming rig, can only be said to be an adequate rendering rig, so don't expect too much.
Caustic will slow a render down to a crawl, even with your 3090. My System has a 3090 I( click My System Below), and it is a problem with many shiny things that means more bouncing, so a lot more calculations.
There's always the possibility to skip pathtracing for animation rendering and use 3Delight, which can be dumbed down infinitely to match your needs. I do semi realistic renders at about 15 - 20 sec/frame. But yeah, if I need all the bells and whistles (bouncelight, SSS etc), rendertimes in 3DL will also skyrocket.
I've been rendering animations for several days, with one shot of 85 frames taking over an hour per frame. It just takes time.
I try to keep it down to roughly 1 frame per minute rendering time (1720x720). Mostly outdoors or well prepared indoors (section nodes, delete everthing not in the frame, etc). Max samples about 1000, post SSIM on but no denoiser. With 1-2 G8 it works quite fine on a 6700k/64GB with a 3080 12GB. 2000x2000 (for which output device?) is overkill.
Using which render engine?
