THIS IS A WINDOWS-ONLY MOD

This mod replaces the traditional exclusive fullscreen mode with a borderless windowed mode that:

• Maintains the same frame latency as exclusive fullscreen
• Maintains support for variable refresh rate technologies such as (fullscreen) G-Sync
• Allows seamless Alt-Tabbing
• Works correctly with overlays

Even when running in windowed mode, this mod can improve frame latency and frame pacing.

Technical Details

This mod replaces Minecraft’s default OpenGL swap chain with a modern DXGI flip-model swap chain.

To accomplish this, the mod moves Minecraft’s OpenGL rendering context into a separate, hidden window. Using DirectX–OpenGL interoperability extensions, the final copy from the internal framebuffer to the back buffer is performed via DirectX11 instead of OpenGL, which allows the use of a DXGI swap chain.

Requirements

• A graphics card that supports:
  • DirectX 11
  • OpenGL
  • The NV_DX_interop2 extension
  • Java >= 23

Known Issues

• V-Sync doesn't seem to reliably work in windowed mode
  • Whether it works or not seems to depend on whether the java executable is called javaw.exe specifically
  • It's likely that there is some kind of compatibility patch from either Windows or the NVIDIA driver involved
  • I'm not sure if screen tearing is even possible in windowed mode with the DXGI flip-model
