I would not fully support this statement. Some benchmarks do not indicate as much performance improvement compared to older cards (especially RX 580 and my personal RX 590) and besides that with the ioreg PerformanceStatistics command in terminal only gpu usage in % is shown, what we can have without that in activity monitor.

Ran some tests with fortnite and WOW and I have found it runs smoother on catalina 10.15.2 and 10.15.3 (both vanilla with only no compat check boot args, updated via mac mini)

My statement is for Radeon VII, not any Polaris card.

Just curious, is there any way to flash the WX 9100 to get the boot screen on a 5,1 like I have with my current GTX 780?

I doubt, and better not to do it anyway for such and expensive card.

Get boot screen by installing OpenCore make much more sense now.

This is still under development, but already can provide boot picker for Polaris and Vega, should also work for WX9100.

Anyway, this is from my own cMP. As you can see from the video. I can boot verbose mode from an unflashed Radeon VII.

I'm not sure what you are referring to regarding the powermod. I tried googling but the only thing that came up was due to the Radeon VII being so power hungry, you would need an external power supply to drive it properly.

While you are experimenting with Twinmotion, try putting the quality on Ultra across the board and then adding tons of grass painted onto sculpted terrain, and then adding lots of trees and plants, in addition to the Archicad model you sync.
Powermod would be the Pixlas mod or external power supply. I too use dual mini 6-pin to 8-pin AND dual SATA power to 6-pin right now with this Vega56. I am planning to do some kind of power mod though, with one of my machines at least.

Red Dragon Vega56 with low bios mode test:
I stole some time today for short experiments with twinmotion. I did not paint any grass on terrains, but I tried some water and about 300 live people in a swimming hall. Twinmotion model consists of 12.2 million polygons and 1.1 GB of textures.

Twinmotion played my model at around 25 FPS constantly at ultimate settings. I know it's not as fast as some or most games do play, but it's easily a workable solution for architectural vizualisation aid. Renders are fast, in seconds or tens of seconds. I think materials need some tweaking, they differ quite a lot from cinerender output in ArchiCAD.

Strangely it played at 25 FPS with almost every setting, low, medium, high or whatever, so it could be the bottleneck is processor or something else, not the Vega56. I noticed Twinmotion did not ever use more than 400% of CPU resources, which means 1/6 of total CPU power in my twelve core setup (12 cores + hyperthreading makes it a total of 2400% max according to apple system performance tool).

From screenshot you can read some performance and resources statistics info; GPU 95% and CPU 55% does not reflect what I said above though, so I don't know why it behaves like it does. I recon it's not a completed product yet, so we'll see what happens later on. I tested few hours without a crash - not bad. Next time something more demanding. And planning to compare this with ProRender in C4D too.

I would think your planned 1st choice of a card (as I read it above) WX9100 would achieve at least this, and probably better.

I am still considering a VII myself. They can be bought under 700€ at times, as new.

edit. without water effects and without any moving people in viewport, I get 102 FPS out of TW.

So, it seems that with Twinmotion 2020 and most higher end real-time archiviz solutions implementing real time ray tracing, the choice is either NVidia's RTX (which is a no go on the Mac) or waiting fro AMD's Navi 20 (or whatever they end up calling it) later this year.

The new Enscape requires RTX (probably because AMD doesn't have a solution yet and it's Windows only so NVidia cards aren't an issue), and Twinmotion 2020 is supposed to utilize the brand new Unreal engine with real time ray tracing capabilities and you will need a GPU that supports that technology.

Unfortunately, no current solution from AMD has this capability, and I'm concerned about spending $1500 on a GPU that seems like it will need to be replaced later this year. Guess I'm waiting.

I've been playing with twinmotion something like a week now. I think I'll settle to this Vega56 (<350€) for now, because of what you say, and because it seems to be enough for most of the cases I've got at hand today. At least if I strip down the model, and build up the environment in TwinMotion instead of ArchiCAD; vegetation and people that is, and textures too.

I get 30 fps or more with live trees (tens of them), wind, snow, birds, about 30-40 live people. I can export a FullHD 3 minute long 30fps video in about 30 minutes. One picture comes out rendered in a second, in seconds or max in ten seconds or so (depends from settings). The quality and looks of the renders are debatable. Some say one can get much more finess out from cinerender or the likes of it (trad. CPU renderers). But cinerender is vastly more difficult to master. This program is quite easy after a couple of days of training.

Interface is not the most versatile, but I guess this is there comes the easy versus versatile confrontation. Difficult to have both.

Below (picture) settings/conditions gives me over 30fps with Vega56 (low bios mode). There are 10-12 PBR lights inside the building, and some glowing items and live swimmers too.

ps. I just saw a new Radeon VII just under 700€ today. I was a little tempted to hit the buy button, but did not.

I hear you. I just don't think I want to spend anything until the new cards come out.

I am already very proficient in Cinema 4D and VRay but use TM when I want to show clients work in progress in real time. If I am doing a photo-realistic rendering, I create my model in Archicad, export it out to C4D, remodel most every element with proper bevels, texture it with VRay materials, and render it out using our render farm (we have one in house). That process takes a lot of time and of course it is not real-time like TM.

I'm very hopeful that the new TM 2020 has the real time ray tracing like they showed off last summer at the Archicad 23 announcement, and at that point (and once AMD has released their new cards), I'll make the investment so that it becomes a long term one, instead of something I am buying today, only to have to purchase again in the near future.

That sounds like a wise decision to me. If you can do by with RX580 for now, no need to rush. I am not trying to convince or anything, just that this is of interest to me too right now. I hope it's allright to use this thread you started for this conversation.

Not at all and I did not take it that way. I am sticking with my NVidia GTX 780 for the time being and will switch to AMD once the new cards are available.

You are welcome to use this thread to continue the discussion. All information is good in my opinion.

just got my Radeon pro w5700 mainly for twinmotion, and looking to test it out tomorrow. I will let you know how it goes.
How did this turn out?

I am looking to upgrade the graphics card in a MacPro5,1 Would run both MacOS AND Windows 10.

It was ok but not as good as I hoped, so I bought a 2080 super and tried bootcamp, which was great .

It depends what you are looking for- great or ok performance.

There is a notable difference in twinmotion on bootcamp to macOS.

Suffice to say after that testing I just built a pc and stuck the rtx into that and the performance is insane, highlighting the obvious performance drop in an egpu.

I have decided no more bootcamp for me and now have both Mac and pc. This was spurred on by the AS move as it is going to happen anyway, and the speed benefits of windows in my apps.
