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 343 FPS, suitable for 144Hz+ monitors. At 1440p, all settings exceed 303 FPS. At 4K, all settings exceed 210 FPS.
The GeForce RTX 4090 is 1051% above the recommended GPU (GeForce GTX 750) for Garry's Mod. The Xeon E-2374G is 4% above the recommended CPU (Core i5).
The Xeon E-2374G determines the performance ceiling at all 1080p settings, all 1440p settings, all 4k settings, while the GPU has headroom.
At 1080p low, the Xeon E-2374G sets the ceiling at about 343 FPS, while the GeForce RTX 4090 could reach 471 FPS. In this scenario, the CPU limits the GPU potential by 27% (FPS gap: 128 FPS). Overall distribution: CPU limits 12/12 cells, GPU limits 0/12, balanced 0/12.
Your Xeon E-2374G 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 27% | CPU Limits GPU 19% | CPU Limits GPU 14% | CPU Limits GPU 6% |
| 1440p (2K QHD) | CPU Limits GPU 22% | CPU Limits GPU 18% | CPU Limits GPU 19% | CPU Limits GPU 19% |
| 4K (Ultra HD) | CPU Limits GPU 13% | CPU Limits GPU 10% | CPU Limits GPU 18% | CPU Limits GPU 22% |
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.
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 4% above and your GPU is 1051% above the recommended specs. High/Ultra at 1080p. Lower settings for higher resolutions.

Yes, the Xeon E-2374G paired with the GeForce RTX 4090 can run Garry's Mod smoothly up to 4k achieving around 210 FPS at Ultra quality. Your GPU is 1051% above the recommended specs, and your CPU is 4% 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.
For Garry's Mod, upgrading the CPU would have the biggest impact on performance. The Xeon E-2374G is currently the limiting factor — the GeForce RTX 4090 has extra headroom that a faster processor could take advantage of. This is especially noticeable at 1080p where CPU performance matters more. CPU-limited 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 Xeon E-2374G 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.
