I am going to start/complete an interior using my 4090RTX, but right away, I am not very optimistic. A simple space, with lots of windows, is taking 35 minutes. My CPU renders in 1/2 the time. Have newer processes leveled the playing field?
Is there any configurations I need to know about? I pulled a 3090 and dropped in the 4090. I also updated the driver. I didn’t go back the the Chaos tested driver. What driver are you running?
I have no clue. I have been reading posts about people getting real long render times using the 4090. So long, they are pissed that they spent so much money on the 4090. What driver are you using?
According to my device manager I’m using ver: 31.0.15.3699. The only thing I tweaked on the file was 1. Assigned the vraysky map to the vray sun you had and deleted the dome light. Other than than, all the same but noise threshold. I set it to .003 and .005 for the light cache version.
Assigned the vraysky map to the vray sun Can you elaborate? I am not seeing any map field in the VRaySun. Are you just letting V-Ray add to the environment slot when you add the sun? I was always told to add a dome and link the environment map into that as well.
I lowered the noise threshold, and things sped up. Why wouldn’t lower the threshold slow things down? Isn’t .01 noisier than .003? .003 with be cleaner and slower, but in fact, it is faster.
.003 and .005 for the light cache gave me a clean images seconds (.4 denoiser)
One minute and clean enough for me! This is what I would expect with the 4090RTX. With my CPU, it was 8 minutes, with DR (44 cores) and 1 minute with the 4090RTX. I will work on DR and GPU, but with this test, DR didn’t have enough time to kick in.
You should expect to see 6 buckets with the RTX 4090(and any other GPU)
I rendered the scene on my RTX 4090, took 2m 42.5s … and on my 3090 takes 4m 20.9s
I also rendered on CPU 5950X 16-core, it took 11m 7.1s (here I’m using the standard V-Ray Renderer)
There is something wrong with your hardware setup, please run the Benchmark tool and report your scores here
You can also do a clean install of driver, and you need to change the respective settings in Windows and Nvidia control panel to get the optimal performance. Please follow the steps in my post
On another note, I can take a look at your setup(to save time and effort and to identify the issue) with remote access today or tomorrow if you have time, message me muhammed.hamed@chaos.com
The scaling between the 3090 and 4090 is not great in this scene because of the scene setup, having no materials. This is normal and is expected to happen. You need something in the frame that pushes your 4090…Once you start adding some materials, you will see the power draw of the GPU climb to double what you have now
On another note, there is no need for Denoiser or DR rendering for now. Run the GPU on some of your scenes to make sure your setup is working as expected first. Here is a good scene that pushes the GPU to its limits, if it doesn’t render on 4m ,27s on your 4090 then something is wrong
