nullmoth/nvidia-macos-driver v2.3.6 is a new version of the unofficial driver that runs NVIDIA GeForce cards through Metal on macOS Sequoia. The changes are written up in the repository's v2.3.6 release notes. The release removed the behaviour of copying the entire window back into system memory on every frame when closing a window or scrolling. So the change in this version is the removal of the per-frame full-window copy, and the published description clarifies what changed and why, but gives no actual performance figures.
Mouse cursor updates were moved to a dedicated thread outside the system cursor lock, and the release notes describe the purpose of this change as reducing compositing latency. Chromium-based browsers now use Metal through ANGLE by default. A bug was also fixed where undefined values could appear on screen when reading colours from error message files. These three changes cover window handling, cursor updates, and the browser's graphics path and error display respectively. According to the repository description, this project is a Metal driver for NVIDIA GeForce cards on macOS Sequoia.
The provided release notes contain no performance measurements and no test environment, however. So how much difference the window handling and cursor update changes make in actual use cannot be judged from this information alone. The fixes are stated concretely, but no comparison backing up the performance effect is given. This release lets you confirm what changed, not how large the effect is.
