Exact steps for others to reproduce the error
Render voronoi procedural with many noise textures displacing the texture coordinates

I do not see any bug here? viewport and final render are usually not the same size, to start with! And not the same number of samples, etc.

If i had a scene full of procedural textures like this it wouldn't be able to be rendered in view port but if i switch border on it could fit. Why is that?

Keep in mind a bug could fall under unexpected behavior and thats pretty unexpected for an end user.

Then please attach here a .blend file with such scene, that you cannot render in viewport but can in real render… Theorical bug is not a bug ;)

Also, please remember mem report during render is merely informative, it does not always reflect reality quite well.

Ok haha well that makes sense :P

One last question you may know the answer to

If you get closer to a procedural texture does it load more of it or is the texture in the scene 100% of the time

Also after posting this i have realized it was the resolution causing it sorry for the useless posts i always make haha <3 keep up the good work :D

regarding procedural tex, each pixel is generated on demand. So yes, the closer you get, the more pixels (texels, actually) will be generated, so if they are cached somewhere (not sure about that), cache will use more mem.
