What Luduvo actually needs

Luduvo hasn't published hardware requirements. This is unofficial, worked out from the engine's own error messages and staff replies. Every line links to where it came from.

In short

You need a Windows PC, a Linux PC or an Apple Silicon Mac, with a graphics card from roughly the last ten years and an up-to-date graphics driver.
Very old graphics cards and some Intel laptop chips from 2016 to 2020 aren't supported yet.
On build 45, lots of Windows PCs that do meet this still can't start the game. That's a Luduvo bug, not your PC.

See the known issues if your PC should work but the game won't start.

Graphics

Windows needs a graphics card and driver with Vulkan 1.3 and the features below, or D3D12 at feature level 12.0 with resource binding tier 2. Vulkan 1.3 message, D3D12 feature level message
Build 45 starts Windows PCs on D3D12 without trying Vulkan first. On 26 Sep, D3D12 was failing at startup on NVIDIA, AMD and Intel cards alike. GTX 1650 on build 45, RX 6600 on build 45, Intel UHD on build 45
Macs need Metal 3. The popup lists Vulkan 1.3, Metal 3 and D3D12 as the options. The popup
Intel 7th to 10th gen integrated graphics (Kaby Lake, Coffee Lake, Comet Lake) are blocklisted for Vulkan. They fall back to D3D12, which currently fails. Comet Lake, Kaby Lake, Coffee Lake
OpenGL isn't planned. A DirectX 11 renderer is in development. Nikhil on backends, Isaac on DirectX 11
matt: "Virtually all GPUs and iGPUs released in the last decade have Vulkan support." Whether they have Vulkan 1.3 depends on the driver. matt's post

Operating system

Windows: 64-bit, with the LuduvoSetup.exe installer. Luduvo download page
macOS: Apple Silicon only, as an unsigned preview. Joining games from the website doesn't work yet; Studio does. Luduvo download page, Nikhil on Mac launching
Linux: x86_64, through install.sh or the .tar.xz download. Luduvo download page, Luduvo FAQ

Processor

Your CPU may need FMA instructions. One player with a 2011 Intel i5-2500 got an illegal instruction crash, but the thread was marked resolved without saying how. unconfirmed The report

Vulkan features the engine asks for

For the technically minded

On top of Vulkan 1.3 itself. If your driver lacks any of these, Luduvo skips that graphics card.
