Heres goes nothing, I think I sorted out all questions I had. Using the YouTube video for Mojave as a guide.

I have Catalina working on my 2011 iMac, had a problem creating a afps partition thru the installer. had to boot into 10.13 to create it.
did not even have to apply the 12,2 post patches. it just booted right to the desktop. no resolution glitches. so far smooth sailing >)

Here are two screenshots; one from supported MBA 7,2 which displays Drift OK and one from MP3,1 with GTX680 that does not. They both show the same Metal spec. Can someone else with an MP3,1 and GTX680 running Catb3 confirm Drift does not run?

And Ars says this:
"macOS_GPUFamily1_v3 is the official name for Metal 2 in High Sierra, which you can actually see in the System Information app under Graphics/Displays." so presumably Family1 v4 is Metal 2.
If so, something else is stopping Drift running.

So...unless I've missed some kind of trick, the only way I can get this to install is if I reformat to APFS and lose everything??? At this moment I have no way to back up a 1/2 terabyte. Please someone tell me there's a way to get around this.
If I create an APFS partition on my hard disk and install there, is that a workable solution? Will I be able to access everything on the macOS Extended (Journaled) side of the house? I really don't want to admit defeat, here.

Well, for one you shouldn't be using this as your main OS, Catalina is still quite buggy. Secondly, at the very least, you should be doing a clean install on a separate hard disk or partition.
Is there a good rule of thumb re: how large the partition should be? Am I able to access my files from the non-APFS portion?
Mac Pro 3,1 CatWoman 1.0b6 updated. Download it here.
What's new:
Five ways to get 6 Gb/s speed on SSDs on a Mac Pro 3,1.
My patch is fully compatible with Dosdude1's installer.
A clean install from Dosdude's installer make is highly recommended.
You can also use a clean install from a Supported Mac.
When running on root volume, the prelinked kernel will be updated.
When running not on the root volume, it will update caches.
What's new:
- Internal SuperDrive Support
- Mac OS Standard | Legacy HFS Support [pre HFS+]
- Old cd's and dvd's in HFS format will mount properly
- I have not tested the DVD player yet.
Five ways to get 6 Gb/s speed on SSDs on a Mac Pro 3,1.
- USB 3.0 support with optional Inateck PCIe card. Runs 6 Gb/s on 16x slot.
- Updated: The two internal SATA II ports behind the fans on the Mobo on the lower left run 3 Gb/s speed. To use the two internal SATA ports you have to route power from somewhere. If not using the DVD drives, you can use power from there. I use one DVD and one SATA III SSD. To get 6 Gb/s you can stripe two drives from these two hidden ports.
- Internal PCIe SSD on 16x slot also runs at 6 Gb/s speed.
- Stripe two SSDs on two of the four SATA II drive bays will result in 6 Gb/s speed (3 Gb/s x 2)
- Stripe two PCIe Card SSDs on two 4x slots (3 Gb/s x 2) Update: In Beta 3, my 4x PCIe Cards with SATA III SSD’s are working at 6 Gb/s each. I may take two of my 256’s and stripe them for greater Speed.
My patch is fully compatible with Dosdude1's installer.

Migration Assistant doesn´t work in DP3. I suppose it´s still buggy.
You should have no problem accessing HFS+ and NFTS volumes from Catalina.
This is rare unless you have legacy CDs and DVDs in pre HFS+ format (HFS).
You may have issues with legacy Mac OS Standard HFS volumes. For this you need the HFS.kext and HFSEncodings.kext from Mojave.

Migration Assistant even when it works runs like garbage. It may be best to boot into Dosdude's installer disk and use ditto to migrate data over form one Data volume to another assuming you can access both disks. If on different computers, you can use Target disk mode that's not the host computer. Never put the host computer in target disk mode, it can result in locked data and may become unbootable especially when cloning a system volume.
What do you mean with "two internal SATA III ports behind the fans on the Mobo"?
[doublepost=1562380435][/doublepost]
I have always used Migration Assistant between machines and worked like a charm for me.
The Mac Pro 3,1 has two hidden internal SATA III ports. They are on the motherboard. The fans in the front where the cheese grater is there they are directly behind the fan. You have to remove the fans to get to them. And you have to use power from either the DVD drive cables with adapters or from one of the video power cables if you have one that's available.
I think Apple added it in the board design to use SATA DVD drives instead of ATAPI ones or it was just designed to add two more hard drives instead of DVDs.
Update: The 4x PCI slots can negotiate at 6 Gb/s. The hidden SATA ports are SATA II. My bad.

Yes I know. But they are SATA II. Not even the Mac Pro 5.1 have SATA III.

Nevermind, My 4x PCIe slots are negotiating at 6 Gb/s. Arg. I have SSDs everywhere.
The two hidden SATA ports are SATA II, but you could stripe them to get 6 Gb/s.

Recently on two supported Macs, I've seen Migration Assistant on Mojave over Gigabit Ethernet say it is going to take 24 hrs with 12 gigs of data. It was running so slow, I had to cancel it and used ditto instead to bring over the user's data. Ditto took 10 minutes.
Migration Assistant used to work great when it would default to Thunderbolt copying over target disk mode. But I haven't seen it run well in years. Most of the time, I just clone the user's entire drive and bring it over to a new machine. Then update it.
I've also seen Time Machine restores take 12 hours.
I'm a fan of imaging disks, but only processes that I can rely on.
these are:
block level:
- dd
- asr
- hdiutil
- ditto
- rsync
- cp
I hope to make all these processes way easier very soon.

I understand. Never used Migration Assistant by ethernet. I use also the clone method in the same machine. But when moving the whole system to another machine, I prefer a clean install and then use the Migration Assistant from a cloned drive and import. As my experience, it´s cleaner.
I guess if it works don't fix it.
Apple may have just broke the Ethernet connection with it. When I was using it the user's system was corruption and it was taking up 500 Gigs, just for the System / OS. In this instance, I did not want to clone the whole thing. For one, the user was migrating to a 500GB SSD and her old Mac was a 1TB HD. Plus there was clearly something wrong with her computer.
I used to do clean installs always, but at our company I am a web developer 1st and IT Manager second, and they don't like it when things take a long time. So I usually clone systems now and then run any updates like Mojave, web browsers, chat software, office, etc. If I was doing IT full-time, I would probably have a standard disk image that every computer used and then run customizations for that user afterwards. I support 30 Macs and develop software full time. They are getting a very good deal.

Very good indeed!
A PCIe 2.0 x1 connection works at 5GT/s 8b/10b (500MB/s without accounting for overhead, with overhead it's around 350MB/s).
A PCIe 2.0 x4 is 2000MB/s, with around 1500MB/s usable after overhead.
6Gbps is a SATAIII connection.
I showed screen captures of the 4x slots negotiating at 6Gb/s.
Your screenshot show a SSD connected to a PCIe SATAIII card, you are using wrong terminology since you can't connect a SATA drive to a PCIe slot without a PCIe SATA card.
What? The SATA3 SSDs with PCIe card on the 4x slot is negotiating at 6gb/s. How is this the wrong terminology?
Previously to beta 3, I have only seen them negotiate at 3Gb/s on a 4x slot and usually only on a 16 x slot you get 6Gb/s on a SATA3 SSD.
Yes it's wrong. You probably wanted to write that you have a PCIe SATA III card:
"Update: The PCIe SATA III card can negotiate at 6 Gb/s. The hidden SATA ports are SATA II. My bad."
You only connect PCIe drives (SAS/PCIe AHCI/NVMe) to the PCIe slots directly.
