This section is based on estimated CPU/GPU FPS ceilings, not utilization percentages.
At 1440p ultra, the Radeon RX 7700 sets the ceiling at about 229 FPS, while the Ryzen 7 7800X3D has headroom up to 450 FPS. In this scenario, the GPU limits the CPU potential by 49% (FPS gap: 221 FPS). Overall distribution: GPU limits 12/12 cells, CPU limits 0/12, balanced 0/12.
Your Radeon RX 7700 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 36% | GPU Limits CPU 45% | GPU Limits CPU 46% | GPU Limits CPU 48% |
| 1440p (2K QHD) | GPU Limits CPU 32% | GPU Limits CPU 41% | GPU Limits CPU 47% | GPU Limits CPU 49% |
| 4K (Ultra HD) | GPU Limits CPU 38% | GPU Limits CPU 44% | GPU Limits CPU 44% | GPU Limits CPU 46% |
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 + Radeon RX 7700 pairing runs this title with CPU utilization between 0% and 15% and GPU utilization between 5% and 32%. Ryzen 7 7800X3D keeps significant headroom across presets, while Radeon RX 7700 is utilized efficiently without persistent saturation. As resolution scales, average GPU load rises from 22% at 1080p to 11% at 4K, while CPU averages move from 0% to 11%.
Neither component is close to saturation: CPU tops out at 15% and GPU at 32%. This pattern suggests possible engine-side limits, an FPS cap, or workload constraints unrelated to raw hardware throughput. It also shows why low utilization does not automatically mean there is no FPS limiter.
At 1080p, averages sit around CPU 0% and GPU 22%. At 1440p, that shifts to CPU 11% and GPU 11%, and at 4K it reaches CPU 11% and GPU 11%. This shows that workload scaling is present on both components, with stronger pressure on the GPU.
1080p (Full HD) Low is the most balanced preset based on this dataset. It runs around CPU 0% (0-0%) and GPU 22% (12-32%), which keeps Radeon RX 7700 well utilized without constant max-out behavior while Ryzen 7 7800X3D remains stable for consistent frame delivery.
Current utilization does not show an urgent upgrade requirement for either component; the Ryzen 7 7800X3D and Radeon RX 7700 remain reasonably matched for this title.
Understanding Hardware Utilization: These percentages represent how much of your component's maximum processing power is actively being used during gameplay. They describe hardware load, but they do not directly tell you which component sets the FPS ceiling.
Important: a CPU or GPU can still be the FPS limiter without reaching 100% utilization. Two processors can both show 40% usage and still deliver very different frame rates, depending on per-core speed, cache, engine threading, driver overhead, and frame preparation efficiency.

Yes, the Ryzen 7 7800X3D paired with the Radeon RX 7700 can run Garry's Mod smoothly up to 4k achieving around 155 FPS at Ultra quality. Your GPU is 569% above the recommended specs, and your CPU is 160% above the recommended requirements.
This CPU + GPU combo costs approximately $783 ($384 CPU (Rank #212 Value) + $399 GPU (Rank #22 Value)). Your build is already very cost-efficient, but if you want even more FPS, the next good option is upgrading the GPU. For example, upgrading to the RTX PRO 5000 Blackwell Mobile (Rank #53 for value) could deliver noticeably better performance.
For Garry's Mod, upgrading the GPU would give you the most noticeable improvement. The Radeon RX 7700 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 Ryzen 7 7800X3D and Radeon RX 7700 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.
