PCI-e cards with Windows drivers

[SpecterSalmon]

This might be a really stupid things to ask, because I'm not too sure how possible this is. I have a capture card that had Windows drivers. I use to use it, and wish to use it again, but there isn't any drivers for it on Linux. It is an internal PCI-e capture card (AVerMedia LiveGamer 4K GC573), and I don't want to replace it with how much I spent on it. In the future, is it at all possible to install Windows drivers in Winboat, and then use the device outside of Winboat? I'm asking for the possibilties of if this is possible, before I concern actually getting a new capture card. Thank you in advance.

Hi! Just wanted to chime in here because I’m dealing with the exact same situation.
Running the official Windows drivers for a PCIe capture card like the GC573 via compatibility layers usually doesn’t work well (or at all) because of kernel-level driver requirements and latency issues. Basically, the card needs native support to be usable for low-latency capture on Linux.
That’s exactly what I’m working on right now: A native Linux driver for the GC573 that runs on modern kernels. It’s already quite stable (DMA and interrupts work), but we’re currently stuck on a final 'black screen' bug.
If you’re interested in keeping your card alive, feel free to check out my profile.
Especially if you have a Windows setup: We actually need help comparing some register logs to fix this last bug. There are instructions in Issue #3 if you want to take a look.
Don’t buy a new card just yet, let’s try to get this one working first!

Since this VM runs in a container, it can't access PCI-e cards using the normal pass-through mechanism. If you want to run a Windows VM on Linux that can access PCI-e cards, you need to create a non-containerized VM. Then you configure the system to pass that card through to the VM. Linux will not have access to any cards you pass through to the Windows VM. Then load the Windows drivers in the Windows VM.
