CPU vs GPU different outcomes (built in v-ray textures)

I’m having different looks in materials wheras using gpu vs cpu, especially with the built in textures from v-ray itself.
Here’s a comparison with the same material but with different outcomes depending on cpu or gpu visualisation.
‘Splat’ as an example; but most of the noise built ins have the same issues.
It’s not only in the asset editor it’s also when you render btw.


Coming from mostly everything being cpu based materials for the last 2 decades, will most materials relying on vray built in textures become obsolete?
Or is there a feature coming , where you can “convert” cpu to gpu materials?

Best regards. ​
