This tactical shooter uses the AnvilNext 2.0 engine and features procedural environmental destruction, which can be taxing on the CPU. The Vulkan API helps older hardware maintain performance by better utilizing available resources. Siege is sensitive to RAM speed and latency. The HD Texture Pack can push VRAM usage over 6GB, so cards with 8GB or more are recommended for the best visual experience at 1080p or 1440p.
Actual FPS may vary based on RAM speed, background processes, and other system factors

At 4k ultra, the Core i5-12400F sets the ceiling at about 80 FPS, while the GeForce RTX 4090 could reach 311 FPS. In this scenario, the CPU limits the GPU potential by 74% (FPS gap: 231 FPS). Overall distribution: CPU limits 12/12 cells, GPU limits 0/12, balanced 0/12.
Your Core i5-12400F 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 49% | CPU Limits GPU 51% | CPU Limits GPU 53% | CPU Limits GPU 56% |
| 1440p (2K QHD) | CPU Limits GPU 63% | CPU Limits GPU 65% | CPU Limits GPU 64% | CPU Limits GPU 67% |
| 4K (Ultra HD) | CPU Limits GPU 70% | CPU Limits GPU 69% | CPU Limits GPU 73% | CPU Limits GPU 74% |
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.

The Core i5-12400F + GeForce RTX 4090 pairing runs this title with CPU utilization between 20% and 95% and GPU utilization between 29% and 83%. Core i5-12400F stays in a controlled operating range, while GeForce RTX 4090 is utilized efficiently without persistent saturation. As resolution scales, average GPU load rises from 57% at 1080p to 59% at 4K, while CPU averages move from 69% to 59%.
The utilization pattern is relatively balanced. The GeForce RTX 4090 reaches 80% average at its highest-load preset, while the Core i5-12400F peaks at 84% average, with no single component consistently acting as a hard bottleneck.
At 1080p, averages sit around CPU 69% and GPU 57%. At 1440p, that shifts to CPU 59% and GPU 59%, and at 4K it reaches CPU 59% and GPU 59%. This shows that workload scaling is present on both components, with stronger pressure on the GPU.
1440p (2K QHD) High is the most balanced preset based on this dataset. It runs around CPU 40% (20-59%) and GPU 80% (78-83%), which keeps GeForce RTX 4090 well utilized without constant max-out behavior while Core i5-12400F remains stable for consistent frame delivery.
Current utilization does not show an urgent upgrade requirement for either component; the Core i5-12400F and GeForce RTX 4090 remain reasonably matched for this title.

Yes, the Core i5-12400F paired with the GeForce RTX 4090 can run Rainbow Six Siege smoothly up to 4k achieving around 80 FPS at Ultra quality. Your GPU is 611% above the recommended specs, and your CPU is 196% above the recommended requirements.
This CPU + GPU combo costs approximately $1759 ($110 CPU (Rank #30 Value) + $1649 GPU (Rank #77 Value)). Your build is already very cost-efficient, but if you want even more FPS, the next good option is upgrading the CPU. For example, the Ryzen 9 9950X is a great upgrade option for around $649 (Rank #5 for value).
For Rainbow Six Siege, upgrading the CPU would have the biggest impact on performance. The Core i5-12400F 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.
Rainbow Six Siege 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.
Rainbow Six Siege requires at minimum a Core i3-560 (CPU) and GeForce GTX 460 (GPU) with 6 GB RAM and 61 GB storage. For the recommended experience, you need a Core i5-2500K and GeForce GTX 670 with 8 GB RAM. Your Core i5-12400F and GeForce RTX 4090 both exceed the recommended specs, so you're well-positioned for a great experience.
These Rainbow Six Siege 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.
