Hey all

I'm a bit at my wits end and hoping to see if someone can provide a hint, or if I just try to return/exchange this RZ30. I purchased the RZ30 along with an Epson QB1000 projector back in April and I've been having nothing but problems. I came from a Sony projector + Pioneer AVR that were 10+ years old and never had any of these issues (using the exact same Apple TV 4K).

I'm having random audio dropouts while using the Apple TV 4K. It doesn't happen WHILE audio is playing, but if I switch apps and go watch something in another app, or just watch another youtube video, quite often the audio will not play. The only way for me to play is to either shut the RZ30 off/on or switch to a different input then back to my Apple TV input.

I've tried changing the HDMI cable I don't know how many times. I do have HDMI-CEC which I would prefer using as I've been using it for years with this Apple TV and it's been fine.

I can't reproduce the issue. For example, I could be watching something on Plex/Netflix then switch to youtube and there's no audio.

I've also had random issues where nothing shows on the screen when I turn everything off, but that's a problem for another day. I'd like to get my audio issues resolved, or I'm just going to junk this POS, it's incredibly frustrating.

Thanks!

Hey all

Edit: not expecting native but I feel 20-30% loss to be a bit excessive.

I've been struggling with running a Windows 11 Gaming VM under Unraid with some types of games (e.g.: Cyberpunk, Forza Horizon 6, few others). I have a pretty beefy system with an i9-14900K, RTX 5070 TI, 24GB of RAM associated to the VM (albeit it's DDR4 - because well that's what I had).

On bare metal, I get about 20-30% better performance in the aforementioned games. I play/test my games in 1440p, so no 4K here. Basically, the issue is getting high FPS - the games are playable for sure, but I can't seem to get the FPS that I am getting when playing on bare metal. Other games (e.g.: Doom Dark Ages) run pretty much on par with bare metal. But Cyberpunk for example, on Ultra settings (even without Ray tracing), the VM struggles to maintain 60-70 fps, whereas on bare metal I can hit 100+.

The other thing, DLSS appears to have absolutely no effect in these games. This seems to contradict YT videos, etc. There are videos I'm seeing where turning on DLSS in Cyberpunk can make an 80-90 fps game go up to 130-140fps on the 5070ti (granted most are with the AMD 9800x3d, but the 14900k should be pretty close).

When running these problematic games, My GPU usage % is sitting at 70-85%, never going over, whereas on bare metal it's consistently at 95+. It's like I can't push more frames. Cyberpunk can even stutter in a VM when running on these ultra or ultra-RT settings.

Here is my XML: https://pastebin.com/kfMsXN9G

A few notes:

• I am not passing through an NVME directly, I have tried this but it makes no noticeable FPS difference (only loading times). I've been keeping the NVME for my bare metal testing. The VM boot image is on an unraid NVME.
• You will notice I am passing through 7 Pcores and their equivalent E-core. I skip cores 0,1 because Unraid tends to sit there. I haven't seen any real difference in performance having tried to do both 8 Pcores and 7Pcores.
• I am not isolating the CPUs, just passing them through. I have tried this and don't see a difference.
• Same for binding VFIO, I have tried force binding the GPU to VFIO and not and performance is identical. I do not have a problem passing the GPU through and once the VM starts, the Unraid host can't see the GPU at all.

This seems tied to the CPU somehow - the reason I suspect this, playing games in 4K yields pretty much the performance I would expect, so hitting GPU thresholds. 1440p doesn't always tax the GPU to full, so in theory you should see higher FPS, which isn't the case under VFIO.

I am at a bit of a loss - I had even upgraded from an i9-10900 (non-K) to this i9-14900K because I thought the 10900 was bottlenecking my GPU, so I upgraded the CPU, keeping the DDR4 RAM I had due to the current pricing of RAM. This has certainly helped, but I'm still hitting these weird performance walls.

Hoping someone can investigate my XML and provide some insights as I'm not really sure what else I can do.

Thanks!

Hey all

Just ordered a Satin Nickel U400 from Apple here in Canada. Came back in stock after a long wait. Not sure about the US/Other regions.

Good luck!
