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.
At 1080p high, the GeForce GTX 980 Ti sets the ceiling at about 334 FPS, while the Ryzen 7 9800X3D has headroom up to 716 FPS. In this scenario, the GPU limits the CPU potential by 53% (FPS gap: 382 FPS). Overall distribution: GPU limits 12/12 cells, CPU limits 0/12, balanced 0/12.
Your GeForce GTX 980 Ti is the limiting side in the heaviest mismatch. This means part of the Ryzen 7 9800X3D frame-generation potential remains unused in those settings.
| Resolution | Low | Medium | High | Ultra |
|---|---|---|---|---|
| 1080p (Full HD) | GPU Limits CPU 43% | GPU Limits CPU 46% | GPU Limits CPU 53% | GPU Limits CPU 53% |
| 1440p (2K QHD) | GPU Limits CPU 43% | GPU Limits CPU 46% | GPU Limits CPU 53% | GPU Limits CPU 53% |
| 4K (Ultra HD) | GPU Limits CPU 43% | GPU Limits CPU 46% | GPU Limits CPU 53% | GPU Limits CPU 53% |
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.

Yes, the Ryzen 7 9800X3D paired with the GeForce GTX 980 Ti can run Left 4 Dead 2 smoothly up to 4k achieving around 154 FPS at Ultra quality. Your GPU is 10612% above the recommended specs, and your CPU is 1724% above the recommended requirements.
This CPU + GPU combo costs approximately $565.38 ($465.38 CPU + $100 GPU). Since the GPU is the main limiting factor, investing in a stronger GPU will improve your framerates and overall value. For example, upgrading to the GeForce RTX 3070 for around $499 (Rank #137 for value) could deliver noticeably better performance.
For Left 4 Dead 2, upgrading the GPU would give you the most noticeable improvement. The GeForce GTX 980 Ti is the limiting factor here, while the Ryzen 7 9800X3D 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, 4k ultra.
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 9800X3D and GeForce GTX 980 Ti 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.
