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, all quality settings exceed 438 FPS, suitable for 144Hz+ monitors. At 1440p, all settings exceed 328 FPS. At 4K, all settings exceed 219 FPS.
The RTX A4000 is 488% above the recommended GPU (GeForce GTX 750) for Garry's Mod. The Ryzen 7 9800X3D is 203% above the recommended CPU (Core i5).
The RTX A4000 sets the FPS ceiling at 1080p ultra, all 1440p settings, all 4k settings, while the Ryzen 7 9800X3D still has additional frame-generation headroom. The FPS ceiling is closely matched at 1080p (low/medium/high).
Approximated average price on current market:
Combo price: $1576.38. At 1080p Ultra, this combo delivers 438 FPS, equivalent to 0.28 FPS per dollar.

This section is based on estimated CPU/GPU FPS ceilings, not utilization percentages. Adjacent heavier settings are lightly stabilized to remove prediction jitter that would otherwise create impossible reversals.
At 4k ultra, the RTX A4000 sets the ceiling at about 219 FPS, while the Ryzen 7 9800X3D has headroom up to 367 FPS. In this scenario, the GPU limits the CPU potential by 40% (FPS gap: 148 FPS). Overall distribution: GPU limits 9/12 cells, CPU limits 0/12, balanced 3/12.
Your RTX A4000 is the limiting side in the heaviest mismatch. This means part of the Ryzen 7 9800X3D frame-generation potential remains unused in those settings.
| Resolution | Low | Medium | High | Ultra |
|---|---|---|---|---|
| 1080p (Full HD) | Balanced | Balanced | Balanced | GPU Limits CPU 18% |
| 1440p (2K QHD) | GPU Limits CPU 9% | GPU Limits CPU 10% | GPU Limits CPU 15% | GPU Limits CPU 33% |
| 4K (Ultra HD) | GPU Limits CPU 13% | GPU Limits CPU 17% | GPU Limits CPU 27% | GPU Limits CPU 40% |
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 and then monotonic-smoothed across heavier presets and resolutions, 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 203% above and your GPU is 488% above the recommended specs. Ultra settings at 1080p, or High at 1440p/4K.

Yes, the Ryzen 7 9800X3D paired with the RTX A4000 can run Garry's Mod smoothly up to 4k achieving around 219 FPS at Ultra quality. Your GPU is 488% above the recommended specs, and your CPU is 203% above the recommended requirements.
This CPU + GPU combo costs approximately $1576.38 ($465.38 CPU + $1111 GPU). Since the GPU is the main limiting factor, investing in a stronger GPU will improve your framerates and overall value. For example, upgrading to the RTX PRO 4500 Blackwell for around $2399 (Rank #299 for value) could deliver noticeably better performance.
For Garry's Mod, upgrading the GPU would give you the most noticeable improvement. The RTX A4000 is the limiting factor here, while the Ryzen 7 9800X3D still has spare capacity. A more powerful GPU would unlock higher FPS, especially at higher resolutions and quality presets. GPU-limited at: 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 Ryzen 7 9800X3D and RTX A4000 both exceed the recommended specs, so you're well-positioned for a great experience.
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.
