Perfect Presentation
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_interop2extension
- 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.exespecifically - 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
