Luduvo bug Stops the game starting Windows, Intel

Intel graphics blocked from Vulkan

Not fixed yet

Luduvo skipped your Intel graphics for Vulkan on purpose, because that driver crashes. It then tried D3D12, which failed too.

What you see

Luduvo fails to launch on a laptop with Intel UHD or HD graphics.

Who's affected

Intel 7th to 10th gen integrated graphics (Kaby Lake, Coffee Lake, Comet Lake), for example UHD 620 and HD 620.

Why it happens

Luduvo blocks these Intel drivers because their Vulkan 1.3 support crashes at runtime. Build 44 falls back to D3D12, which then hits the D3D12 startup bug.

What to do

  1. There's nothing you can fix on your end yet. A newer Intel driver doesn't take these chips off the list.
  2. The real blocker is the D3D12 bug listed with this. Once that's fixed, the fallback should get you in.

Don't bother with

  • Setting LDV_VK_SKIP_BLOCKLIST=1. It gets further, then the game floods with Device Removed errors.
  • Installing the LunarG Vulkan runtime or older Intel drivers. Players in thread 2616 tried both.

Status

Still open as of build 45.

How the Doctor spots it

It looks for log lines like these (patterns, not exact text):

  • skipped: Intel
  • non-conformant Vulkan 1.3 driver
