Only Adobe can answer those question. This is an Adobe Photoshop User forum user here do no work for Adobe though some Adobe employee drop in here from time to time. They would most likely not be at liberty to divulge information like that here.
That depends a lot on what you mean by "high poly count".
We have people using 10 million polygon models without too many problems (assuming their GPU is up to it).
Beyond 10 mil polygons, yes, Photoshop is a bit slow and we're trying to improve it.
If Photoshop can't open the files - then we need to get a copy of the files to see why.
How much ram do you have? What video do you have and how much ram is on that card? Are you a mac or windows user? What version is your operating system?
These all can play a role on how well Photoshop or any other 3d app performs when accessing a 3d model and when rendering.
Hi Everyone. Thank you for writing back. I have two 2011 imacs running intel 2.93 ghz, one with 20gb or ram and one with 16gb, both have 1tb hard drives, 1gb vram, one running os 10.6 the other 10.9. I have a 3rd computer, a PC that notably handles the files more quickly, but still crashes if it doesn't like something from the original 3d model. This one has a 3.7ghz intel quadcore processor, 24gb of ram, 3tb hard drive, and a 4gb nvidia geforce video card, running Windows 8.1.
So the reason I make the statement about Photoshop and not about my computers, is that all the above computers can handle the original files in zbrush. All the above computers can handle the files in meshlab. With ease. But when I get to photoshop, I face long load times, crashing, and a lag using the tools within the 3d space. And sometimes it handles the models differently than it does in any other 3d program. It seems picky for lack of a better word.
When I say high poly count, I mean 4 million to 8 million. I am able to knock down the poly count in meshlab and that can help. But sometimes the files just don't want to open in Photoshop.
With all that said, it may be in something how some of the models were built, but again, Photoshop is the only one having an issue. And I have to add that I have been using Photoshop for 20 years and I absolutely love it. I am trying to make a case for my company to use it for coloring, lighting, and processing 3d models, but I just can't with the above issues.
Any help would be greatly appreciated.
Chris, if you need files, I can see about getting them to you. The only real issue is the work is highly proprietary and kept under wraps. So I would need to get approval and feel comfortable that is will be protected. Thanks!
Thing is you can't really judge other apps against zbrush as zbrush was designed from the ground up to handle millions of polygons. Some of the high end 3d apps are just getting that ability.
We handle proprietary files all the time. We use them to debug and verify fixes, then dispose of them as requested - but we do need a copy of the files to debug against.

Chris, what is the best way to get you a couple of files? I believe they're a few hundred mb each. Thank you.
Dropbox, Creative Cloud file sharing, etc.
(and zip them before copying them -- many will compress a bit)
