Hello can I can Poser 11 and Poser 12 at the same time on a PC? I would try to test Poser 12

Yes. I do it on two different machines.

I have only one fast machine. Can I install both versions on the same machine?

Yes. Here's 12 and 11 running at the same time.

Their installations will work like this.

The Appdata/Roaming folders with the preferences of each one:

I can only confirm on Windows though, as I don't use Mac.

Yes. I have both P11 and P12 running on the same machine. I have that configuration on two separate computers.

Aha crosspost. Haven't done that in years.

I do that far too often for my tastes LMAO

Yes, just don't install one over the other (use 2 different folders) but that's probably a given. I have 4 versions of poser on my machine. And I've had at least 3 of them running at the same time.

Lots of cross-posts this morning. But the OP has his answer.

Yes, both can coexist while open but don't try to render them at the same time.

Not only can you run both versions, I highly recommend it. If you want to use your old Python scripts, you need to have Poser 11, since Poser 12 won't run them (yet).

There is a free 21 day trial, so you can see for yourself. One overwriting the other shouldn't be a problem, since Poser 11 installs in a folder called Smith Micro and Poser 12 installs in one called Poser Software.

I've rendered on CUDA GPU in P12 while rendering on CPU in p11 before. Was working alright :D

Didn't try both on GPU or both on CPU at once though - P11 can't render on my GPU, and rendering on CPU when I can use optix in P12 is too much of a waste of time.

Edit: alright yeah maybe don't try it if you're not running on a powerful computer. Mine's a bit of a freak.

Can confirm the same multi-version parallel Poser execution on macOS. I can't speak for simultaneous renders, though. I've never had a supported GPU, so each Poser instance would have to share the CPU. That's bound to be more efficient letting them run sequentially, though.

I don't have GPU rendering. I have tried duel CPU renders. If I set both renders to use half of the cores, it managed. If I forgot that, the computer shut down in protest.
