This section is based on estimated CPU/GPU FPS ceilings, not utilization percentages. Adjacent heavier settings are lightly stabilized to remove prediction jitter that would otherwise create impossible reversals.
At 4k ultra, the GeForce RTX 3080 Ti sets the ceiling at about 198 FPS, while the Ryzen 7 9800X3D has headroom up to 367 FPS. In this scenario, the GPU limits the CPU potential by 46% (FPS gap: 169 FPS). Overall distribution: GPU limits 12/12 cells, CPU limits 0/12, balanced 0/12.
Your GeForce RTX 3080 Ti is the limiting side in the heaviest mismatch. This means part of the Ryzen 7 9800X3D frame-generation potential remains unused in those settings.
| Resolution | Low | Medium | High | Ultra |
|---|---|---|---|---|
| 1080p (Full HD) | GPU Limits CPU 13% | GPU Limits CPU 18% | GPU Limits CPU 28% | GPU Limits CPU 36% |
| 1440p (2K QHD) | GPU Limits CPU 20% | GPU Limits CPU 23% | GPU Limits CPU 33% | GPU Limits CPU 40% |
| 4K (Ultra HD) | GPU Limits CPU 33% | GPU Limits CPU 33% | GPU Limits CPU 40% | 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 and then monotonic-smoothed across heavier presets and resolutions, not generic utilization heuristics.

Yes, the Ryzen 7 9800X3D paired with the GeForce RTX 3080 Ti can run Garry's Mod smoothly up to 4k achieving around 188 FPS at Ultra quality. Your GPU is 711% above the recommended specs, and your CPU is 203% above the recommended requirements.
This CPU + GPU combo costs approximately $1015.38 ($465.38 CPU + $550 GPU). Your GeForce RTX 3080 Ti 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. For example, upgrading to the GeForce RTX 4080 for around $1199 (Rank #290 for value) could deliver noticeably better performance.
Your GeForce RTX 3080 Ti 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 9800X3D and GeForce RTX 3080 Ti 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.
