Garry's Mod on Radeon R9 270X

Meets minimumEstimate · medium confidence, ±20%

Yes, at lower settings. The Radeon R9 270X meets Garry's Mod's minimum spec but not the recommended one. We estimate ~42 fps at 1080p high (range 34–50, medium confidence, ±20%), GPU-limited. For 60 fps at 1080p, use the low preset. Its 2 GB of video memory is below the 4 GB the game recommends. The cheapest current card for 60 fps at 1080p high is the Radeon RX 6400 (~60 fps).

Estimate · medium confidence, ±20%

Estimated FPS from our model (v0), based on the game's published requirements and relative GPU/CPU performance. Not measured. Real results vary with drivers, patches, and scenes. Values above 300 fps show as 300+. Data updated 2026-09-24.

Best settings

60 fps at 1080p: low preset
60 fps at 1440p: not reachable
144 fps at 1080p: not reachable

AMD card: use FSR in quality mode before dropping the preset (XeSS also works). DLSS is not available on Radeon.

What limits performance

Estimates above: GPU-limited, assuming a processor fast enough not to hold the Radeon R9 270X back.
Processor needed for ~42 fps: Core i3-9100F or faster (slowest current desktop CPU our model expects to keep up).
With the recommended CPU: still GPU-limited at 1080p high, ~42 fps.

Video memory

Radeon R9 270X: 2 GB
Minimum spec: 1 GB (+1 GB headroom)
Recommended spec: 4 GB (2 GB short)
