Fuzzy / Blurry PNG image on GPU

[Israel3d]

Hi,

I'd like to share a problem which I haven't successed solving by myself. Would like your help.
There's a bit of fuzziness over GPU (interactiv and production).
Image is lit by the default dome light at 2048 resolution.

Thanks!

Can you just for the test, set resolution to something like 8k, to see if it is any better ?

No, just takes longer time to render. Outcome similar to the image posted originally.

Okay, thanks for testing. Support guys will check it out and get back.

Best,
Blago.

Btw, what is the original resolution of the texture ?

Would it be possible to send the scene along the external assets for investigation?

Sure, check your inbox.

I got the files and will check them in a few minutes.
What is the V-Ray version that you are using?

Thanks for the information.
GPU Texture Resizing is activated so all the textures are resized to 512px 8-bit image.

Disable the texture resizing completely or using a higher quality Image Resizing will make the final result the same or closer to the one from the CPU rendering.

So it wasn't a hardware issue...
Thanks a lot!

It's not a hardware issue.
V-Ray has an option for texture resizing which could be very useful for quick scene optimization.
It was enabled in your scene and the texture of the DomeLight has been shrinked to 512 pixels which makes it look very blurry.

Hi guys,

I'm checking another case which is similar to what I've submitted in the first place.
Please see a significant decline in HDRI quality when switching to GPU while optimized.

Hello, Moshe,
Could you please pack the project and send it over for investigation in a private message to me or addressed at support@chaosgroup.com ?

Kind regards,
Peter
