Quoted from Distrowatch.com: The Linux Mint team, having published new versions of both the project's Ubuntu- and Debian-based branches, have turned their attention to working on new features and performance improvements. Two areas which have received a lot of attention are the Cinnamon desktop and the Nemo file manager. The distribution's monthly newsletter reports: "The star of the month within the Cinnamon team is Jason Hicks. Last month we talked about VSYNC, input lag and performance improvements within the Muffin window manager. This is now a reality and it's all been merged in preparation for Muffin 4.0. Input lag was reduced on NVIDIA cards and the window manager feels more responsive when moving windows. You now also have the possibility to turn off VSYNC in the System Settings. This basically delegates VSYNC to your GPU driver (which needs to handle it otherwise you get screen tearing) and if that driver performs well, it can eliminate input lag and boost performance. Jason also ported a huge amount of upstream changes from the GNOME project: Similar to Mutter, Muffin now uses its own embedded version of COGL and Clutter, which received most of the patches applied to the one in GNOME. Many Mutter performance improvements were applied to Muffin. CJS received many commits from GNOME's GJS, including improvements to its garbage collection."
