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 431 FPS, suitable for 144Hz+ monitors. At 1440p, all settings exceed 372 FPS. At 4K, all settings exceed 285 FPS.
The GeForce RTX 4090 is 1051% above the recommended GPU (GeForce GTX 750) for Garry's Mod. The Core Ultra 7 265U is 36% above the recommended CPU (Core i5).
At lower resolutions (1080p low), the Core Ultra 7 265U sets the FPS ceiling. As graphical load increases at (1080p (high/ultra)), the GeForce RTX 4090 becomes the FPS-limiting side. The FPS ceiling is closely matched at 1080p medium, all 1440p settings, all 4k settings.
This section is based on estimated CPU/GPU FPS ceilings, not utilization percentages.
At 1080p ultra, the GeForce RTX 4090 sets the ceiling at about 359 FPS, while the Core Ultra 7 265U has headroom up to 428 FPS. In this scenario, the GPU limits the CPU potential by 16% (FPS gap: 69 FPS). Overall distribution: GPU limits 2/12 cells, CPU limits 1/12, balanced 9/12.
The Core Ultra 7 265U and GeForce RTX 4090 stay close in effective frame-generation ceiling across most presets, so neither side consistently suppresses the other by a large margin.
| Resolution | Low | Medium | High | Ultra |
|---|---|---|---|---|
| 1080p (Full HD) | CPU Limits GPU 8% | Balanced | GPU Limits CPU 8% | GPU Limits CPU 16% |
| 1440p (2K QHD) | Balanced | Balanced | Balanced | Balanced |
| 4K (Ultra HD) | Balanced | Balanced | Balanced | Balanced |
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 Core Ultra 7 265U + GeForce RTX 4090 pairing runs this title with CPU utilization between 15% and 32% and GPU utilization between 3% and 15%. Core Ultra 7 265U 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. It also shows why low utilization does not automatically mean there is no FPS limiter.
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 Ultra 7 265U remains stable for consistent frame delivery.
Current utilization does not show an urgent upgrade requirement for either component; the Core Ultra 7 265U 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 Core Ultra 7 265U paired with the GeForce RTX 4090 can run Garry's Mod smoothly up to 4k achieving around 285 FPS at Ultra quality. Your GPU is 1051% above the recommended specs, and your CPU is 36% 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 high, 1080p ultra. CPU-limited at: 1080p low.
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 Ultra 7 265U 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.
