Hi there, im Adrian. I need your guys help on building a powerful and versatile PC for Live Interactive Visuals and Multi-projection.
We are currently a Team of three, Composer, Audio and Visual Programmer and me as an Assistant Visual Programmer.
The Composer will be performing with Ableton, Live Instruments and Pre-programmed Clips. The Command Interface is based on OSC wich will come from an over Computer.
Setup Contains four 4K 65" TV’s in Portrait Mode (QH65R), 2 Macbooks wich will run the Audio part on Stage and the Visual PC running Touch Designer as the Visual Output feed.
At the moment we have a iMac Pro 18-core Intel W (4.3GHz Turbo) and a Radeon Pro Vega 64 with 16GB of VRAM. It build the most of the Touch Designer Networks and could Manage 4x4K Outputs as well the Build in 5K Screen.
Because you cannot build a Mosaic on macOS, I needed to create a Container wich splits the incoming Network patch into four equal screens. We have 8640 x 3840 Screen Size. The Final Output Container was build so that whatever we throw at it, it will always crop it to the right dimensions.
But maybe theres room for improvements or even a better solution.
Sadly because I rarely used the Forum, I cannot add an attachment yet.
We noticed that the iMac Pro is struggling in the GPU department. It’s stuck around 50 fps but with barely any Visual change. GPU… completely obsolete for the Multi Display Purpose. This machine (iMac Pro) Was not purposely bought for Touch Designer. Wished was 60 fps because our Monitors run on 60Hz.
But we need a PC to run our Live Visual on that Scale. So what I read from the Derivative Wiki is that, Higher Clocks Count, only one GPU is supported by one Instance of Touch Designer, that SLI/NVLink is not supported and Nvidia Quadrois the way to go.
There are many factors wich are stopping me to build one: AMD dropped there ZEN3 lineup with an Ryzen 9 5950X 16-core and 4.9GHz Turbo Clock, the new and upcoming RTX 6000A Quadro GPU and PCIe 4.0.
The X570 Supports 24 PCIe Lanes (PCIe4.), while other Chipsets like the TRX40 support 88 PCIe Lanes (PCIe4), wich is mind boggling. The Ryzen Threadripper 3960X 24-Core has the highest Turbo Clock with up to 4.5 GHz. Would get a decent Board and try to overclock it a little.
Now to the GPU’s. The Quadros still available atm are the RTX 4000, 5000, 6000 and 8000.
In total we need 5 Outputs, 4 for Performing and one for controlling the Network. Theres also the possibility that we maybe want to hook up 4 more Projectors for a total of 9 Outputs total.
Those would have been my build options:
Two RTX 5000 with a NV Link to maximise Output Count. The NV Link wouldn’t serve for better Touch Designer Performance Instead for the Sync between between the screens, tearing and also setting up Mosaic.
Having one RTX 5000 and one RTX 4000 for the Displays
One RTX 5000 and two RTX 4000 for the Displays.
Now here come the questions:
- Is RTX Quadro Supported in Touch Designer?
- Intel preferred over AMD Threadripper?
- Will the second and third GPU Build work without one of those Quadro Sync II Cards or are they desperately needed?
- Does the first Build even make sense?
- Is the RTX 6000 a better Solution?
- Should I dunk PCIe 4.0 Support and rather go with a Board that only supports last gen?
And If somebody could respond as soon as possible that would be really nice. We have a deadline and it needs to be up and running on 15th November.
