This section is based on estimated CPU/GPU FPS ceilings, not utilization percentages.
At 4k high, the EPYC 9184X sets the ceiling at about 217 FPS, while the GeForce RTX 4090 could reach 343 FPS. In this scenario, the CPU limits the GPU potential by 37% (FPS gap: 126 FPS). Overall distribution: CPU limits 12/12 cells, GPU limits 0/12, balanced 0/12.
Your EPYC 9184X 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 21% | CPU Limits GPU 23% | CPU Limits GPU 26% | CPU Limits GPU 28% |
| 1440p (2K QHD) | CPU Limits GPU 30% | CPU Limits GPU 32% | CPU Limits GPU 34% | CPU Limits GPU 36% |
| 4K (Ultra HD) | CPU Limits GPU 33% | CPU Limits GPU 34% | CPU Limits GPU 37% | CPU Limits GPU 37% |
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 EPYC 9184X + GeForce RTX 4090 pairing runs this title with CPU utilization between 0% and 7% and GPU utilization between 15% and 45%. EPYC 9184X keeps significant headroom across presets, while GeForce RTX 4090 is utilized efficiently without persistent saturation. As resolution scales, average GPU load rises from 34% at 1080p to 22% at 4K, while CPU averages move from 0% to 4%.
Neither component is close to saturation: CPU tops out at 7% and GPU at 45%. 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 34%. At 1440p, that shifts to CPU 4% and GPU 22%, and at 4K it reaches CPU 4% and GPU 22%. 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 34% (22-45%), which keeps GeForce RTX 4090 well utilized without constant max-out behavior while EPYC 9184X remains stable for consistent frame delivery.
Current utilization does not show an urgent upgrade requirement for either component; the EPYC 9184X 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 EPYC 9184X paired with the GeForce RTX 4090 can run Garry's Mod smoothly up to 4k achieving around 173 FPS at Ultra quality. Your GPU is 1051% above the recommended specs, and your CPU is 261% above the recommended requirements.
This CPU + GPU combo costs approximately $5399 ($3750 CPU (Rank #494 Value) + $1649 GPU (Rank #77 Value)). Your EPYC 9184X 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 processor with a significantly better value rating. For example, the EPYC 4585PX is a great upgrade option for around $699 (Rank #66 for value) while costing less than your current CPU.
Your EPYC 9184X is already an incredibly powerful processor. While it's technically the first component to hit its limit (which is completely normal in state-of-the-art builds), there is no meaningful upgrade path that would drastically improve your Garry's Mod performance right now. CPU 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 EPYC 9184X 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.
