macOS guests use Apple’s own ParavirtualizedGraphics framework, which comes with none of the downsides of virtio-gpu. It pipes through serialised Metal at native performance.

No. It isn’t up to par. But that’s AMD’s problem. No standard spec would solve a lack of software development investment of a hardware vendor, especially for a device as complex as a GPU. (meanwhile, on the Intel side, oneAPI looks to be ve

CUDA is what ended up replacing it, or rather, OpenCL had always failed to make a dent over the long term. (with AMD ROCm being a CUDA API clone, without the PTX layer)

It’s no more secure than the security isolation guarantees given by the GPU driver stack to a regular process. No more guarantees are provided than that. I’d consider the VMM as even more untrusted than before when VirGL is used, with alway

The new (.NET Core then .NET 5 onwards) runtimes aren't installed automatically. But when you install them manually, they are serviced for security updates through Windows Update, so that you don't have to do that manually.

When in a Linux VM yes. Know however that box64 doesn't have exactly ideal perf characteristics, quite the reverse. Especially on that (recent) hardware.
