Hi,
I bought new RTX 4090 and its super slow on VRay GPU rendering in 3dsmax. It seems that it render few seconds and then stop for a few seconds and then render again and repeate. Its much slower then 3090 for some reason. But I tested fstorm and fstorm render without any problem. Is there something I can do?
Thank you.
It is MSI Gaming Trio X.
Thank you for any help.

Hi @Jiri.Matys may I ask what fixed your issue? Is it the clean driver reinstall that you mentioned in the other thread?
No one answer here so I post it in regular 3ds max GPU thread where you answered, sorry about that.
And yes, clean driver install helped again.
I have a thread somewhere about problem on 3090. Problem was different - rendering animation was slower every frame but with no reason for that. After clean nvidia driver installation problem was gone. And now this 4090 problem was also fixed with clean reinstall. You should probably mention somewhere with big letters that its recommended to clean reinstall nvidia drivers before GPU rendering, at least in 3ds max 
Its curious that Vray bench worked without any problem.
Although my graphics card (RTX 4070 Ti ASUS TUF Gaming 12GB) is weaker than yours, I think my renderings are faster!
I think your problem is only software.
Use the latest driver as well as Windows 11 …
