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 454 FPS, suitable for 144Hz+ monitors. At 1440p, all settings exceed 366 FPS. At 4K, all settings exceed 263 FPS.
The GeForce RTX 5090 is 1074% above the recommended GPU (GeForce GTX 750) for Garry's Mod. The Xeon w5-2555X is 261% above the recommended CPU (Core i5).
The Xeon w5-2555X sets the FPS ceiling at 1080p (medium/high/ultra), 1440p (medium/high/ultra), 4k (medium/high/ultra), while the GeForce RTX 5090 still has headroom. The FPS ceiling is closely matched at 1080p low, 1440p low, 4k low.
Approximated average price on current market:
Combo price: $3845. At 1080p Ultra, this combo delivers 454 FPS, equivalent to 0.12 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.
This CPU/GPU pair is mostly balanced in Garry's Mod. Across tested presets: GPU limits in 0/12, CPU limits in 0/12, and balanced in 12/12. Peak observed performance in the sampled cells is around 691 FPS.
The Xeon w5-2555X and GeForce RTX 5090 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) | Balanced | Balanced | Balanced | Balanced |
| 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 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 261% above and your GPU is 1074% above the recommended specs. Ultra settings at 1080p, or High at 1440p/4K.

Yes, the Xeon w5-2555X paired with the GeForce RTX 5090 can run Garry's Mod smoothly up to 4k achieving around 263 FPS at Ultra quality. Your GPU is 1074% above the recommended specs, and your CPU is 261% above the recommended requirements.
This CPU + GPU combo costs approximately $3845 ($1145 CPU + $2700 GPU). Your Xeon w5-2555X 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 processor with a significantly better value rating. For example, the EPYC 9375F is a great upgrade option for around $5306 (Rank #5 for value).
Your Xeon w5-2555X is already an incredibly powerful processor. While it's technically the first component to hit its limit (which is completely normal in state-of-the-art builds), there is no meaningful upgrade path that would drastically improve your Garry's Mod performance right now. CPU fully utilized at: 1080p medium, 1080p high, 1080p ultra, 1440p medium, 1440p high, 1440p ultra, 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 w5-2555X and GeForce RTX 5090 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.
