Garry's Mod on Radeon RX 580
Yes. The Radeon RX 580 meets Garry's Mod's recommended spec. We estimate ~84 fps at 1080p high (range 67–101, medium confidence, ±20%), GPU-limited. For 60 fps at 1440p, use the medium preset (~59 fps on high). Its 8 GB of video memory covers the 4 GB the game recommends. Model estimate, not measured; data updated 2026-09-24.
Estimated FPS by preset
| Preset | 1080p | 1440p | 4K |
|---|---|---|---|
| low | 143 | 100 | 60 |
| medium | 109 | 76 | 46 |
| high | 84 | 59 | 35 |
| ultra | 67 | 47 | 28 |
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: ultra preset
- 60 fps at 1440p: medium preset
- 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 RX 580 back.
- Processor needed for ~84 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, ~84 fps.
Video memory
- Radeon RX 580: 8 GB
- Minimum spec: 1 GB (+7 GB headroom)
- Recommended spec: 4 GB (+4 GB headroom)
