This section is based on estimated CPU/GPU FPS ceilings, not utilization percentages.
At 1080p low, the GeForce RTX 4060 sets the ceiling at about 406 FPS, while the Ryzen 7 5800X3D has headroom up to 634 FPS. In this scenario, the GPU limits the CPU potential by 36% (FPS gap: 228 FPS). Overall distribution: GPU limits 11/12 cells, CPU limits 0/12, balanced 1/12.
Your GeForce RTX 4060 is the limiting side in the heaviest mismatch. This means part of the Ryzen 7 5800X3D frame-generation potential remains unused in those settings.
| Resolution | Low | Medium | High | Ultra |
|---|---|---|---|---|
| 1080p (Full HD) | GPU Limits CPU 36% | GPU Limits CPU 31% | GPU Limits CPU 30% | GPU Limits CPU 35% |
| 1440p (2K QHD) | GPU Limits CPU 21% | GPU Limits CPU 22% | GPU Limits CPU 24% | GPU Limits CPU 8% |
| 4K (Ultra HD) | GPU Limits CPU 17% | GPU Limits CPU 22% | GPU Limits CPU 22% | 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 Ryzen 7 5800X3D + GeForce RTX 4060 pairing runs this title with CPU utilization between 12% and 43% and GPU utilization between 9% and 59%. Ryzen 7 5800X3D keeps significant headroom across presets, while GeForce RTX 4060 is utilized efficiently without persistent saturation. As resolution scales, average GPU load rises from 18% at 1080p to 45% at 4K, while CPU averages move from 26% to 28%.
Neither component is close to saturation: CPU tops out at 43% and GPU at 59%. 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 26% and GPU 18%. At 1440p, that shifts to CPU 28% and GPU 24%, and at 4K it reaches CPU 28% and GPU 45%. This shows that GPU demand scales sharply with resolution while CPU load remains comparatively stable.
4K (Ultra HD) Medium is the most balanced preset based on this dataset. It runs around CPU 28% (15-42%) and GPU 46% (33-59%), which keeps GeForce RTX 4060 well utilized without constant max-out behavior while Ryzen 7 5800X3D remains stable for consistent frame delivery.
Current utilization does not show an urgent upgrade requirement for either component; the Ryzen 7 5800X3D and GeForce RTX 4060 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 Ryzen 7 5800X3D paired with the GeForce RTX 4060 can run Left 4 Dead 2 smoothly up to 4k achieving around 111 FPS at Ultra quality. Your GPU is 15172% above the recommended specs, and your CPU is 1192% above the recommended requirements.
This CPU + GPU combo costs approximately $728 ($429 CPU (Rank #295 Value) + $299 GPU (Rank #12 Value)). Your build is already very cost-efficient, but if you want even more FPS, the next good option is upgrading the GPU. For example, upgrading to the GeForce RTX 3070 Ti for around $599 (Rank #37 for value) could deliver noticeably better performance.
For Left 4 Dead 2, upgrading the GPU would give you the most noticeable improvement. The GeForce RTX 4060 is the limiting factor here, while the Ryzen 7 5800X3D still has spare capacity. A more powerful GPU would unlock higher FPS, especially at higher resolutions and quality presets. GPU-limited at: 1080p low, 1080p medium, 1080p high, 1080p ultra, 1440p low, 1440p medium, 1440p high, 1440p ultra, 4k low, 4k medium, 4k high.
Left 4 Dead 2 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.
Left 4 Dead 2 requires at minimum a Pentium 4 3.0GHz (CPU) and GeForce 6600 (GPU) with 2 GB RAM and 13 GB storage. For the recommended experience, you need a Core 2 Duo 2.4GHz and GeForce 7600 with 2 GB RAM. Your Ryzen 7 5800X3D and GeForce RTX 4060 both exceed the recommended specs, so you're well-positioned for a great experience.
These Left 4 Dead 2 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.
