This section is based on estimated CPU/GPU FPS ceilings, not utilization percentages.
At 4k low, the Ryzen 7 PRO 5750GE sets the ceiling at about 242 FPS, while the GeForce RTX 4090 could reach 344 FPS. In this scenario, the CPU limits the GPU potential by 30% (FPS gap: 102 FPS). Overall distribution: CPU limits 10/12 cells, GPU limits 0/12, balanced 2/12.
Your Ryzen 7 PRO 5750GE is the limiting side in the heaviest mismatch. This means part of the GeForce RTX 4090 rendering potential remains unused in those settings.
| Resolution | Low | Medium | High | Ultra |
|---|---|---|---|---|
| 1080p (Full HD) | CPU Limits GPU 11% | CPU Limits GPU 6% | Balanced | Balanced |
| 1440p (2K QHD) | CPU Limits GPU 26% | CPU Limits GPU 23% | CPU Limits GPU 21% | CPU Limits GPU 19% |
| 4K (Ultra HD) | CPU Limits GPU 30% | CPU Limits GPU 28% | CPU Limits GPU 27% | CPU Limits GPU 23% |
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 PRO 5750GE + GeForce RTX 4090 pairing runs this title with CPU utilization between 19% and 32% and GPU utilization between 3% and 15%. Ryzen 7 PRO 5750GE keeps significant headroom across presets, while GeForce RTX 4090 is utilized efficiently without persistent saturation. As resolution scales, average GPU load rises from 9% at 1080p to 9% at 4K, while CPU averages move from 30% to 24%.
Neither component is close to saturation: CPU tops out at 32% and GPU at 15%. 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 30% and GPU 9%. At 1440p, that shifts to CPU 24% and GPU 9%, and at 4K it reaches CPU 24% and GPU 9%. 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 30% (27-32%) and GPU 9% (3-15%), which keeps GeForce RTX 4090 well utilized without constant max-out behavior while Ryzen 7 PRO 5750GE remains stable for consistent frame delivery.
Current utilization does not show an urgent upgrade requirement for either component; the Ryzen 7 PRO 5750GE and GeForce RTX 4090 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 PRO 5750GE paired with the GeForce RTX 4090 can run Garry's Mod smoothly up to 4k achieving around 205 FPS at Ultra quality. Your GPU is 1051% above the recommended specs, and your CPU is 59% above the recommended requirements.
This CPU + GPU combo costs approximately $1998 ($349 CPU (Rank #311 Value) + $1649 GPU (Rank #77 Value)). Since the CPU is the main limiting factor, investing in a stronger processor will improve your framerates and overall value. For example, the Ryzen 9 9950X is a great upgrade option for around $649 (Rank #5 for value).
For Garry's Mod, upgrading the CPU would have the biggest impact on performance. The Ryzen 7 PRO 5750GE is currently the limiting factor — the GeForce RTX 4090 has extra headroom that a faster processor could take advantage of. This is especially noticeable at 1080p where CPU performance matters more. CPU-limited at: 1080p low, 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 PRO 5750GE 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.
