The “GSF” is the new AutoCAD 2022 (and the Specialized Toolsets) graphics system and an acronym for Graphics System Fabric.
“GSF is a completely new cross platform 3D graphics system being developed for AutoCAD, leveraging all the power of modern GPUs and multi-core CPU to offer a smooth navigation experience for much larger drawings.”
The AutoCAD Team is looking for your feedback on a GFS update.
