Any reasonably modern motherboard can accept any reasonably modern PCIe GPU. Issue with prebuilts is more commonly the powersupply and lack of cables. And that budget would be?

Best bet would be https://www.nexusmods.com/subnautica/search/ — A quick search didn't find anything like that. To be more clear: a mod can only add that capability if the general architecture of the game engine already supports a feature that allows to render to a texture. Even then it would likely be difficult to implement and not perform too well.

Technically? Yes. Practically? No, unless the developer of the game implements such a feature or you find a mod that adds it.

What does per-core CPU usage look like? Sounds like you might be CPU limited. Though ray tracing killing performance in Elden Ring is kind of expected

Not enough in the sense that Windows has to move data from physical RAM to swap a lot because the programs you're using require more than what is available

The CAD program might be using the C drive as some sort of scratch disk for temporary files. Or as @TheProfosist said, if you have very too little RAM, the computer might be swapping a lot. You could try moving the swap file to the HDD, though that will be a ton slower. And maybe check the CAD program for any kind of temporary file setting. ~edit: You could also open Task Manager or better Resource Monitor while you're working, sort by disk usage and see which processes are making heavy use of the disk.

And your operating system and SSD in question are? Maybe provide a bit more info about the system in general and what you're using it for. The writes have to come from somewhere, so it's going to matter whether you're simply playing games or encoding terabytes of video data or something.

From what I'm able to find the cable should be able to do 32.4 Gbps (which would be HBR3). 1440p, 10 bpc, 240 Hz requires 30.77 Gbps, so the cable should be up for it. Maybe it was defective or the specs are plain wrong, but yeah you'll need a cable that supports HBR3 (cables are not versioned, they are rated by the maximum bandwidth they support, even if the version is often used for marketing purposes)

They need to contact Google support, there's nothing anyone of us can do about that.

Could've potentially been a very recent card at a time the open source driver didn't support it yet.

Because those Microsoft keys are pre-installed, since secure boot if effectively a Microsoft feature? If an OS could simply enroll new keys during installation, it wouldn't really protect against anything.

It's the CPU's integrated memory controller that needs to recognize it, the board just provides the physical connection between RAM and CPU. Anything above 2666 MT/s generally requires XMP to be enabled in the BIOS. https://www.gigabyte.com/Motherboard/B450M-DS3H-rev-1x/sp#sp According to their specs, they support 3600 MT/s

Considering that the cheapest R5 5600 I can get around here is 110€, yes that's a scam. If it seems to good to be true, it almost always is.

Yes, should be possible. I've got an R9 5900X with DDR4 running at 3600 MT/s, CL16.

Even then you can't use more than 4 of those at the same time. You'll need some form of workstation GPU, not a gaming one.

As the others have said, the concept of ray tracing has been around for a long time. Movies have used it for special effects, or for entire movies for decades. However, ray tracing is very compute intensive, which is why it can't really be done on a CPU if you want to achieve playable frame rates. For example for Toy Story 3 it took an average of 7 hours to render a single frame. Just as graphics cards have accelerated raster graphics for ages, they are now doing the same thing for ray tracing. Games like Descent (1994) and Quake (1996) already used 3D raster graphics. However, you could only play them at low resolutions—e.g. 320 x 200—because CPUs simply weren't fast enough to run them at a sufficient frame rate (~30 fps) otherwise. That's were GPUs came in: they provided hardware acceleration for things like texturing, allowing for much higher resolutions and frame rates. You could suddenly play these games at 640 x 480 @ 60 fps, while also using much better looking textures. These "fake RT" shaders are doing one of two things: they are either using raster algorithms that emulate ray tracing as much as possible, or are doing ray tracing at much lower resolution and/or precision. Just like games back in 199x had to compromise on a lot of things to achieve 30 fps, these shaders have to compromise to achieve good enough performance. The use of RT cores simply means you can now do the same thing at much higher speeds, while also using higher output resolution while using algorithms that are more precise.

I would assume that's it. Objects close to a light source can often cause glitches in lighting systems, because shadows get really large

Difficult to tell if it's wrong, since your geometry and light setup are completely different from their example. I would try to recreate that as much as possible to compare. Maybe you've found an edge case where the shader simply breaks. As far as I can see, the whole thing is marked as a beta. Are you combining it with any other shaders? Also note the author's comments:

I assume you've enabled all hardware virtualization features in your computer's BIOS? How much RAM and how many cores did you assign to the VM? Which other settings did you use for the VM (e.g. chipset, tpm, enabled features, processor, acceleration, …)? Latest version of Virtual Box? If it hangs, then at some point Virtual Box should pop up a guru meditation error.

Please be more specific, which brands? If it didn't happen with your previous card and happens with multiple driver versions, I would assume the card you're using right now has some kind of hardware issue.

I doubt anyone can tell you without more information. Which specific shader(s) cause the issue? What does the issue look like? (Maybe provide a screenshot) Could be an issue with the GPU, but could also simply be a bug with the particular shader. Is it the RX 580 4 GB or 8 GB? If the shaders are more demanding, could potentially be an issue of too little VRAM.

Brand means nothing. If you buy a cheap product from a well known brand, it's not going to be any better than a cheap product from a lesser known brand. I'd go by reviews of specific products, rather than who made the product.

From my experience PCIe 3 vs 4 makes virtually zero difference in games. I have both in my system and notice no difference based on where a game is installed. Load time seems usually not limited by IO, but for example decompression speed on the CPU.

No, that's the whole difference between type-1 and type-2. Placing the scheduler on the same level as your guests isn't going to make any relevant difference. Your guest should already run at somewhere above 90% native performance with a type-1 HV.
