Reasons NOT to switch to GPU rendering?

[Streetwise]

Are there any compelling reasons not to make the switch? I primarily produce single 3000x3000 interior renders. GPU certainly looks intriguing. Do all of the materials render the same way? Any drawbacks?

Thanks.

You can't use Forest Pro and RailClone, which is a deal-breaker for me.

You can try materials and features yourself without having GPU.
V-Ray GPU works on CPU (can run CUDA on CPU) - just switch the engine to V-Ray GPU and go to Perf. settings and check the CPU device.

You will be able to render all your scenes and check how well it will work for you. Forest Pro and other 3rd party plugins are supported for most use cases.

Best,

What exactly are the found issues with Forest?
I was using it the other day after upgrading my gear, to check stuff out. I noticed it was looking fine and then I began to see it was not rendering how it should, so
some things were fine but other objects were rendering black, meaning I had to switch and of course things took longer.

Then only reason for me is if you dont have the right hardware.
Everything below two 2080Ti is not worth it imo.
I hope for new cards this year. 3080Ti im ready.

Forest Pro materials render at render time, which GPU doesn't support.

Hardware, although I made an upgrade to a 2080ti, it isn't enough. But that's my problem .
Another thing is RAM, most of my scenes take op +64GB RAM and I hate optimizing textures or anything else. (I sometimes have 16K+ textures that I made myself and I do need them that big sometimes).
ColorCorrect plugin isn't supported (and other ones that I use), that means I have to redo most of my library. (Unless someone can write a script to convert all my ColorCorrect settings to an equivalent of ColorCorrection settings (which is going to be hard, if at all possible).)
Dent, Cellular maps,.. isn't supported either.
No 2D displacement, huge dealbreaker.
Only partial OSL support.
Partial Berconnoise support.
Only 6 layers per composite map. (Although 6 is quite enough most of the time).

If the last ones were fixed, I would give a shot but, hardware and memory is still an issue in that case. And I don't like switching from one engine to another one, depending on the scene (interior or exterior). So still CPU for me, for at least a few years I guess .
