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
Performance Report
At 1080p, all quality settings exceed 447 FPS, suitable for 144Hz+ monitors. At 1440p, all settings exceed 393 FPS. At 4K, all settings exceed 302 FPS.
The GeForce RTX 4090 is 1051% above the recommended GPU (GeForce GTX 750) for Garry's Mod. The Core 7 240H is 87% above the recommended CPU (Core i5).
The GeForce RTX 4090 determines the performance ceiling at all 1080p settings, 1440p ultra, 4k ultra, executing at maximum capacity. The system is well balanced at 1440p (low/medium/high), 4k (low/medium/high).
At 1080p ultra, the GeForce RTX 4090 sets the ceiling at about 359 FPS, while the Core 7 240H has headroom up to 441 FPS. In this scenario, the GPU limits the CPU potential by 19% (FPS gap: 82 FPS). Overall distribution: GPU limits 6/12 cells, CPU limits 0/12, balanced 6/12.
Your GeForce RTX 4090 is the limiting side in the heaviest mismatch. This means part of the Core 7 240H frame-generation potential remains unused in those settings.
| Resolution | Low | Medium | High | Ultra |
|---|---|---|---|---|
| 1080p (Full HD) | GPU Limits CPU 12% | GPU Limits CPU 14% | GPU Limits CPU 17% | GPU Limits CPU 19% |
| 1440p (2K QHD) | Balanced | Balanced | Balanced | GPU Limits CPU 6% |
| 4K (Ultra HD) | Balanced | Balanced | Balanced | GPU Limits CPU 9% |
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.
The displayed percentages are derived from FPS ceilings, not generic utilization heuristics.

The Core 7 240H + GeForce RTX 4090 pairing runs this title with CPU utilization between 15% and 32% and GPU utilization between 3% and 15%. Core 7 240H 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 29% to 22%.
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.
At 1080p, averages sit around CPU 29% and GPU 9%. At 1440p, that shifts to CPU 22% and GPU 9%, and at 4K it reaches CPU 22% 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 Core 7 240H remains stable for consistent frame delivery.
Current utilization does not show an urgent upgrade requirement for either component; the Core 7 240H and GeForce RTX 4090 remain reasonably matched for this title.
Understanding Hardware Utilization & Bottlenecks: These percentages represent how much of your component's maximum processing power is actively being used during gameplay. This is the key to identifying performance bottlenecks in any system.
Data generated by our Machine Learning engine trained on real-world benchmarks. Shows the approximate average utilization at each setting.
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 87% above and your GPU is 1051% above the recommended specs. Ultra settings at 1080p, or High at 1440p/4K.

Yes, the Core 7 240H paired with the GeForce RTX 4090 can run Garry's Mod smoothly up to 4k achieving around 302 FPS at Ultra quality. Your GPU is 1051% above the recommended specs, and your CPU is 87% above the recommended requirements.
Price data is not currently available for this combination. In general, look for setups where the CPU and GPU are balanced — this ensures you're not overspending on one component that the other can't keep up with.
Your GeForce RTX 4090 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 ultra, 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 7 240H 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.
