Will my PC run Garry's Mod?
Compare each row above with your own hardware. Meeting the minimum specification targets roughly 30 FPS at 1080p on low settings; the recommended specification targets around 60 FPS at 1080p on medium to high. Use the VRAM calculator to check whether your graphics card has enough memory for your resolution, and the PSU calculator before an upgrade.
