A Source engine sandbox where performance depends entirely on the mods and contraptions you spawn. RAM errors are common on systems with only 4GB.
Actual FPS may vary based on RAM speed, background processes, and other system factors
Performance Report
At 1080p, frame rates range from 53 to 106 FPS depending on quality settings. At 1440p, frame rates range from 40 to 80 FPS. At 4K, frame rates range from 23 to 53 FPS.
The GeForce GTX 485M is 29% below recommended, but 615% above minimum for Garry's Mod. The Ryzen 7 7800X3D is 160% above the recommended CPU (Core i5).
The GeForce GTX 485M sets the FPS ceiling at all 1080p settings, all 1440p settings, all 4k settings, while the Ryzen 7 7800X3D still has additional frame-generation headroom.
This section is based on estimated CPU/GPU FPS ceilings, not utilization percentages.
At 4k ultra, the GeForce GTX 485M sets the ceiling at about 27 FPS, while the Ryzen 7 7800X3D has headroom up to 130 FPS. In this scenario, the GPU limits the CPU potential by 79% (FPS gap: 103 FPS). Overall distribution: GPU limits 12/12 cells, CPU limits 0/12, balanced 0/12.
Your GeForce GTX 485M is the limiting side in the heaviest mismatch. This means part of the Ryzen 7 7800X3D frame-generation potential remains unused in those settings.
| Resolution | Low | Medium | High | Ultra |
|---|---|---|---|---|
| 1080p (Full HD) | GPU Limits CPU 69% | GPU Limits CPU 72% | GPU Limits CPU 73% | GPU Limits CPU 76% |
| 1440p (2K QHD) | GPU Limits CPU 67% | GPU Limits CPU 71% | GPU Limits CPU 72% | GPU Limits CPU 76% |
| 4K (Ultra HD) | GPU Limits CPU 73% | GPU Limits CPU 77% | GPU Limits CPU 78% | GPU Limits CPU 79% |
We estimate the maximum FPS the processor can sustain and the maximum FPS the graphics card can sustain in each setting, then compare those limits directly.
Limit Factor formula: (stronger - weaker) / stronger. Example: if CPU ceiling is 200 FPS and GPU ceiling is 140 FPS, then GPU limits CPU by 30%.
CPU Limits GPU means the processor ceiling is lower. GPU Limits CPU means the graphics ceiling is lower. Balanced means the FPS ceilings are close enough that the gap is negligible.
A component can still be the FPS limiter without reaching 100% utilization. The displayed percentages are derived from FPS ceilings, not generic utilization heuristics.
See how your processor and graphics card compare against the game official minimum and recommended system specs. The placement of your hardware is calculated using relative synthetic performance scores to help you gauge overall playability.
Your CPU is 160% below recommended and your GPU is 29% below recommended, but both meet minimum specs. Playable at Low/Medium settings, 1080p or below.

The Ryzen 7 7800X3D and GeForce GTX 485M will struggle to run Garry's Mod at smooth framerates. At 1080p Ultra, you can expect around 53 FPS which is classified as "playable". Consider lowering settings or upgrading your hardware.
Price data is not currently available for this combination. In general, look for setups where the CPU and GPU are balanced — this ensures you're not overspending on one component that the other can't keep up with.
For Garry's Mod, upgrading the GPU would give you the most noticeable improvement. The GeForce GTX 485M is the limiting factor here, while the Ryzen 7 7800X3D still has spare capacity. A more powerful GPU would unlock higher FPS, especially at higher resolutions and quality presets. GPU-limited at: 1080p low, 1080p medium, 1080p high, 1080p ultra, 1440p low, 1440p medium, 1440p high, 1440p ultra, 4k low, 4k medium, 4k high, 4k ultra.
Garry's Mod does not currently support Frame Generation technologies like DLSS 3 or FSR 3. Your performance is based entirely on native rendering. If the game adds support in a future update, newer GPUs will benefit the most.
Garry's Mod requires at minimum a Pentium 4 (CPU) and GeForce 6 series (GPU) with 4 GB RAM and 5 GB storage. For the recommended experience, you need a Core i5 and GeForce GTX 750 with 8 GB RAM. Your setup meets the minimum requirements but falls short of the recommended specs. You may need to lower some settings for smooth performance.
These Garry's Mod FPS results are not arbitrary numbers. They come from calculations informed by thousands of real gaming benchmarks, and the typical accuracy range is around 10% to 15%. That makes them far more useful than generic FPS calculators that simply invent values without a benchmark foundation. Actual in-game performance can still vary with drivers, updates, RAM configuration, cooling, and the exact scene being rendered.
Performance estimates are based on synthetic benchmarks and hardware capabilities.
Results may vary based on drivers, OS, and background processes.
