I have just done tests with only one video cable connected to the rx7900xtx and with none (using intel internal for graphics) and they both produced the same behaviour. All tested DAWs crash upon switching to GPU.

An event log points to gpu_audio_amd.dll as the culprit. I have sent email to vsl support and posted on gpu-audio discord.

Hi @bcslaam, I just forwarded your info to the engineers, please bear with me a few days more

@bcslaam, the issue ticket is created. We'll get back to you once I hear the solution details from the dev team. Thanks for sharing the info!

So I just saw in reply yesterday to someone else on discord that GPU Audio dont currently support the rx7000 series. @Sasha T ?

Are you aware that it says on the VSL Powerhouse page that the AMD RX7000 series is supported?

Hi @bcslaam. It looks like the library that is included in VSL distribution indeed doesn't have a 7000 series GPU supported, however, we support it in the other library version we have prepared internally, so it's a question of getting the update provided from us to VSL and then - to the customers.

I am working on this with the engineers and I want to see if we can ship it anytime soon or not.

Thanks Sasha T.

It is still not clear, in any documentation, that running your monitors on the same card is possible without glitching audio. Given that the card is powerful enough.

For example the rx7900xtx I bought for powerhouse is almost as powerful as nvidia rtx4090. I assumed I could run my 4 monitors as well as a moderate MIR project at least, since there was nothing saying that I couldnt, or even to be weary of it.

I just saw this question in the other thread and replied. It should work smoothly but really depends on the case. We have confirmed tests of 100+ instruments with Dolby Atmos 7.1.4 (12 channel) output and it worked well for even single GPU setup for both operating systems. However, Mac OS X was quite a bit more stable (for M1 Pro and more powerful setups).

For RTX 4090, you definitely can now today! Do you have another, embedded GPU in your CPU? e.g. AMD APU or Intel CPU with Irix or UHD graphics? If yes, then, you can assign any graphics works on the embedded GPU and have RTX 4090 (or any other GPU) purely dedicated to GPU AUDIO, and this way, you can guarantee smooth work. But this is just an advanced tip, you can also proceed with a single GPU setup for Windows.

And thanks for all the comments you commit, we do appreciate it and we'll collect all the info and update our FAQ / guidelines based on your experience and other people!

I do have my old AMD RX580 which can go in the slot my UAD card is in. So, reading between the lines here, it is reccommended to run Powerhouse on a dedicated headless card. Especially if you run 2 or more monitors, and especially if you are on windows.

Perhaps there are a few things that the Powerhouse documentation needs to address so you dont snag more people like me who have spent thousands based on the little info available and want to keep using AMD cards in their DAW.

1. AMD cards give better latency for VSTi and are generally less disruptive for dedicated DAW machines. As has been discussed on many threads. Thus your continued efforts to get the current RX7000 series up and running will be appreciated.
2. Most people are going to assume they can run their monitors on the same card.
3. There would be many potential users of silicon Macs that run at least 2 monitors. And of course many windows users with multiple monitors. The documentation needs to be up front and clear that running monitors on the card will affect performance and perhaps even stability. A few case scenarios is needed so we know were we're at with this.
4. CPU lanes in motherboards these days are scarce and running two video cards will be a drag for many people. Will bifurcation also effect performance and stability? ie Running two video cards will almost certainly cause them to both run at 8x each on the PCIe slot.

Hi @bcslaam. Thanks for the feedback, we'll use this for our future updates of FAQ and guidelines!

Regarding your setup case, I replied in DM.
