Erro-There is no device available for rendering! NEW RTX 4090 card

[waldob]

Hi team - Just bought a RTX 4090 Asus Tuff.

Vray does not want to render in RTX mode. Can in Cuda and CPU mode.

When I test my card on D5 render in full RTX mode it works fine.

Please help. is it a driver issue?

I have installed the latest Studio driver 535.98.

Run Vray 5.2
CPU i9 13900KF
64 GB Windows 10

Thank you.

Hello @waldob ,

Please provide following information so we could investigate your issue further:

• First, please install the current recommended drivers 531.41 version. You can find this information on the top of this page: V-Ray GPU | GPU rendering by Chaos. Please note that this is the version that is tested and approved by the developers and how it works with V-Ray, so it can be different from the latest version released by NVIDIA.
• Then please run V-Ray Benchmark in V-Ray RTX mode and share a screenshot of your results.
• Apart from that please let us know the exact V-Ray version you have currently installed (Extensions>V-Ray>Help>About V-Ray).
• Also please check GPU Device Selection settings, example:
  
  

​Also please kindly note that we have merged your topic from SketchUp section into this one in the GPU section.

Thank you so much Natalia - Should I download the Game ready driver or the Studio 531.41. I have downloaded Vray benchmark - will test it now.

I am running Vray 5.20.06 for Sketchup 2021.

Have installed 531.41

Natalia - all is working now!!

Thank you so much for your support.

Thank you @waldob for sharing your V-Ray Benchmark scores. Unfortunately the score you get for both CUDA and RTX is significantly lower than expected.

You can compare your results on V-Ray Benchmark results page to other user-submitted results with the same hardware configurations. For example, the average score for one NVIDIA GeForce RTX 4090 is 5000 vrays: example.
This difference can indicate some hardware issues, which is why I would like to suggest you to test your GPU with other available GPU benchmarking software. You can find some useful suggestions in this article.

Another possibility is a driver issue that was discussed in this forum thread. You can test installing older drivers as suggested in this post and running V-Ray Benchmark again.

While testing V-Ray Benchmark please also run a TechPowerUp GPU-Z to check GPU temperature and record a video with GPU-Z Sensors Tab opened.
If possible, also test current 531.41 with V-Ray Benchmark and GPU-Z as well and let us know the temperatures (video will be most helpful).

Should I download the Game ready driver or the Studio 531.41.
We recommend installing Studio drivers. Also, during installation to ensure deleting previous versions you can click on Custom (Advanced) installation > Perform a clean installation.
Please see examples below:

Exception in CORE: Internal error. Please save and restart as soon as possible!​
Can you please also test a new empty scene and any other of your scenes? Do you get this error in every scene?

Morning Natasha - I have installed driver 528.49 and I have installed driver 531.41(clean installation)

Please scores below. Not much difference.

Also I have record the Benchmark test displaying the GPU temp. It runs around 47degrees. Starts at 97 and drops down after 3 seconds.

When I open Wondershare Flimora to edit the clip I noticed that the the GPU temp was about 80 ish degrees.

How can I send you the GPU temp clip it is 60mb.

Also need to test other benchmark software still.

Thank you.

Natalia - please see also bench mark test for D5 and comparison

hardware from other users.

Hey @waldob

Like what my colleague Natalia suggested, your scores for both V-Ray RTX benchmark and D5 render Benchmark is lower than expected. Nearly half of what you should expect out of your GPU. This is because of a performance bug in the current drivers, we have been working closely with Nvidia to find a solution. This performance bug happens on GPUs connected to monitors, which I think it is in your case.

• Please download this driver
• Do a clean install like the screenshots Natalia posted above
• Restart your machine when the new driver is installed(important)
• Go to Nvidia Control Panel, Manage 3D settings, change Power Management mod to Prefer Maximum Performance then click Apply. See the screenshot attached
• Run the Benchmarks again and post the results here
• If you still have low scores we will schedule a remote session with Team Viewer to check your setup

Thank you and have a nice day!

Best,
Muhammed

Hi Muhammed,

THANK YOU SO MUCH. Fantastic advice. Look at my scores now I have spend allot of money on my new upgrade - finally can use it to its full potential.

Keep up the good work.
