Borderless Gaming Patch Notes — January 29, 2026
Aggregated from Steam, cross-tracked with Battle.net coverage on GamePatchNote.
New Features
Slang-based BGFX - Effects now use Slang as the shader foundation, enabling cross-platform support for the upcoming SteamDeck and Linux release.
DX12 Renderer - DirectX 12 is now available and being A/B tested. If you experience issues, launch with
--no-dx12to use the DX11 pipeline.
Profile-Guided Optimization - Effect compilation now uses PGO for your GPU rather than trying to be one-size-fits-all, so system resource usage at runtime has dramatically reduced and should resolve hammering of weaker GPUs.
The cross-GPU resource sharing was fixed for Intel GPUs
You can now also set LUTs borders, and other custom textures in BGFX. Transparency can also be enabled so when combined you can do things like this:
Coming Soon
Vulkan renderer (with Linux release)
Native SteamDeck/Linux support

The new BGFX effect format documentation and all effects are available at: github.com/andrewmd5/bgfx-slang - Contributions welcome!
A Personal Note
I'm currently dealing with some personal tragedy, so updates will slow down while I grieve. I've brought someone on to handle bug fixes and maintenance during this time. I apologize in advance for any slow communication on my part; if something is critical, please ping in the Discord.
Thank you for your understanding and continued support.
