First playthrough!
This is my first attempt at a reasonably good looking factory.

4 Heavy Modular Frames / Minute.

This game is gonna get tough isn't it?

I managed to strap a NVIDIA GeForce rtx 3060 12gb into a Dell Poweredge r730xd using proxmox and IOMMU pci-slot passthrough. I've seen a lot of posts saying this was impossible, so this is here to demonstrate otherwise. In addition, the performance drop that is introduced when using IOMMU is <5%. Here's how I did it:

The main problem with consumer GPU's in a r730 is that NVIDIA cards will throw an "error 43" exception if it notices that it is plugged into a VM (NVIDIA wants VM-users to use enterprise-level GPUs). This can be bypassed easily in proxmox by adding the "hidden=1" tag to the CPU cores that were attached to the VM.

The second issue is physical space and/or cooling. Both of these issues can be solved by mounting the GPU outside the case - shown in the images - using a PCI ribbon cable (make sure you use one with high EM shielding) and a 8-pin PCI power connector. The links to both parts are below.

If someone would like a detailed software and hardware explanation, I can give that. This post is mainly to show that it can be done. Look at the task-manager window for proof.

The cables:
8-pin PCI power cable: link; the cable looks strange, but it works.
PCI ribbon cable: link.
Consider getting longer versions of both cables. As the images show, mine are a bit short, which leads to a sub-optimal mounting situation.

Java AWT is a super annoying medium for custom graphics. Because of this, I wrote a tool that handles the rendering and timing of each frame, while running on a dedicated thread. Take a look at the repo here:
