Official Garry's Mod system requirements, player reports on Garry's Mod performance, and a check against your GPU and CPU.
Published on the Steam store page by the developer. This is that text, not a benchmark.
Garry's Mod generally runs well on most systems, providing a smooth experience with popular hardware and settings, though heavy addons and large maps may impact performance.
Drawn from 12 reviews that mention performance.
Pick a GPU and a CPU. The result compares their class with the parts named in the official requirements. It is not an FPS estimate.
