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

The GeForce RTX 4070 Ti is 853% above the recommended GPU (GeForce GTX 750) for Garry's Mod. The Core i5-13600K is 185% above the recommended CPU (Core i5).
The GeForce RTX 4070 Ti sets the FPS ceiling at all 1080p settings, all 1440p settings, all 4k settings, while the Core i5-13600K still has additional frame-generation headroom.
Approximated average price on current market:
Combo price: $909. At 1080p Ultra, this combo delivers 256 FPS, equivalent to 0.28 FPS per dollar.

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 high, the GeForce RTX 4070 Ti sets the ceiling at about 211 FPS, while the Core i5-13600K has headroom up to 341 FPS. In this scenario, the GPU limits the CPU potential by 38% (FPS gap: 130 FPS). Overall distribution: GPU limits 12/12 cells, CPU limits 0/12, balanced 0/12.
Your GeForce RTX 4070 Ti is the limiting side in the heaviest mismatch. This means part of the Core i5-13600K frame-generation potential remains unused in those settings.
| Resolution | Low | Medium | High | Ultra |
|---|---|---|---|---|
| 1080p (Full HD) | GPU Limits CPU 18% | GPU Limits CPU 18% | GPU Limits CPU 25% | GPU Limits CPU 28% |
| 1440p (2K QHD) | GPU Limits CPU 18% | GPU Limits CPU 18% | GPU Limits CPU 25% | GPU Limits CPU 28% |
| 4K (Ultra HD) | GPU Limits CPU 30% | GPU Limits CPU 30% | GPU Limits CPU 38% | GPU Limits CPU 38% |
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.
See how your processor and graphics card compare against the game official minimum and recommended system specs. The placement of your hardware is calculated using relative synthetic performance scores to help you gauge overall playability.
Your CPU is 185% above and your GPU is 853% above the recommended specs. Ultra settings at 1080p, or High at 1440p/4K.

Yes, the Core i5-13600K paired with the GeForce RTX 4070 Ti can run Garry's Mod smoothly up to 4k achieving around 126 FPS at Ultra quality. Your GPU is 853% above the recommended specs, and your CPU is 185% above the recommended requirements.
This CPU + GPU combo costs approximately $909 ($319 CPU + $590 GPU). Your GeForce RTX 4070 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 5090 D for around $1999 (Rank #374 for value) could deliver noticeably better performance.
Your GeForce RTX 4070 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 Core i5-13600K and GeForce RTX 4070 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.
