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 345 FPS, suitable for 144Hz+ monitors. At 1440p, all settings exceed 356 FPS. At 4K, all settings exceed 263 FPS.
The GeForce RTX 4090 is 1051% above the recommended GPU (GeForce GTX 750) for Garry's Mod. The Ryzen 9 7950X3D is 372% above the recommended CPU (Core i5).
No major FPS-ceiling mismatch detected. The GeForce RTX 4090 and Ryzen 9 7950X3D stay close in effective frame-generation ceiling across the tested resolutions and quality settings.
Approximated average price on current market:
Combo price: $2135. At 1080p Ultra, this combo delivers 345 FPS, equivalent to 0.16 FPS per dollar.

This section is based on estimated CPU/GPU FPS ceilings, not utilization percentages.
At 1080p ultra, the Ryzen 9 7950X3D sets the ceiling at about 344 FPS, while the GeForce RTX 4090 could reach 366 FPS. In this scenario, the CPU limits the GPU potential by 6% (FPS gap: 22 FPS). Overall distribution: CPU limits 1/12 cells, GPU limits 0/12, balanced 11/12. Confidence is low because both ceilings are very close in this cell.
The Ryzen 9 7950X3D and GeForce RTX 4090 stay close in effective frame-generation ceiling across most presets, so neither side consistently suppresses the other by a large margin.
| Resolution | Low | Medium | High | Ultra |
|---|---|---|---|---|
| 1080p (Full HD) | Balanced | Balanced | Balanced | CPU Limits GPU 6% |
| 1440p (2K QHD) | Balanced | Balanced | Balanced | Balanced |
| 4K (Ultra HD) | Balanced | Balanced | Balanced | Balanced |
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.

Yes, the Ryzen 9 7950X3D paired with the GeForce RTX 4090 can run Garry's Mod smoothly up to 4k achieving around 263 FPS at Ultra quality. Your GPU is 1051% above the recommended specs, and your CPU is 372% above the recommended requirements.
This CPU + GPU combo costs approximately $2135 ($486 CPU (Rank #102 Value) + $1649 GPU (Rank #77 Value)). This is a well-balanced setup, meaning you're getting good value from both components without significant waste.
This setup is already well-balanced for Garry's Mod. No significant bottleneck - CPU and GPU are well matched across all settings. Both the Ryzen 9 7950X3D and GeForce RTX 4090 complement each other effectively, so upgrading either component individually would yield diminishing returns. If you want more FPS, you'd benefit most from upgrading both CPU and GPU together.
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 9 7950X3D and GeForce RTX 4090 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.
