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 54 to 140 FPS depending on quality settings. At 1440p, frame rates range from 42 to 90 FPS. At 4K, frame rates range from 23 to 56 FPS.
The RTX PRO 6000 Blackwell Server Edition is 1175% above the recommended GPU (GeForce GTX 750) for Garry's Mod. The Ryzen 7 7800X3D is 160% above the recommended CPU (Core i5).
The RTX PRO 6000 Blackwell Server Edition 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.
Approximated average price on current market:
Combo price: $8583. At 1080p Ultra, this combo delivers 54 FPS, equivalent to 0.01 FPS per dollar.

This section is based on estimated CPU/GPU FPS ceilings, not utilization percentages.
At 4k ultra, the RTX PRO 6000 Blackwell Server Edition sets the ceiling at about 29 FPS, while the Ryzen 7 7800X3D has headroom up to 130 FPS. In this scenario, the GPU limits the CPU potential by 78% (FPS gap: 101 FPS). Overall distribution: GPU limits 12/12 cells, CPU limits 0/12, balanced 0/12.
Your RTX PRO 6000 Blackwell Server Edition 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 63% | GPU Limits CPU 67% | GPU Limits CPU 73% | GPU Limits CPU 76% |
| 1440p (2K QHD) | GPU Limits CPU 61% | GPU Limits CPU 65% | GPU Limits CPU 62% | GPU Limits CPU 69% |
| 4K (Ultra HD) | GPU Limits CPU 68% | GPU Limits CPU 68% | GPU Limits CPU 75% | GPU Limits CPU 78% |
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.

The Ryzen 7 7800X3D and RTX PRO 6000 Blackwell Server Edition will struggle to run Garry's Mod at smooth framerates. At 1080p Ultra, you can expect around 54 FPS which is classified as "playable". Consider lowering settings or upgrading your hardware.
This CPU + GPU combo costs approximately $8583 ($384 CPU + $8199 GPU). Your RTX PRO 6000 Blackwell Server Edition provides phenomenal top-tier performance but at a premium enthusiast price. Since you are essentially at the ceiling of current hardware capabilities, there are no meaningful performance upgrades available. However, if you wanted a more cost-effective build that still delivers a great experience, you could theoretically step down to a high-end card with a significantly better value rating.
Your RTX PRO 6000 Blackwell Server Edition is already a top-tier graphics card. While it's technically the limiting factor here (which means you are fully utilizing your GPU's visual horsepower exactly as intended), there is no meaningful upgrade path that would drastically improve your Garry's Mod performance right now. GPU fully utilized 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 Ryzen 7 7800X3D and RTX PRO 6000 Blackwell Server Edition 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.
