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

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 low, the Core i7-8086K sets the ceiling at about 352 FPS, while the GeForce RTX 4090 could reach 932 FPS. In this scenario, the CPU limits the GPU potential by 62% (FPS gap: 580 FPS). Overall distribution: CPU limits 12/12 cells, GPU limits 0/12, balanced 0/12.
Your Core i7-8086K 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 62% | CPU Limits GPU 56% | CPU Limits GPU 50% | CPU Limits GPU 46% |
| 1440p (2K QHD) | CPU Limits GPU 49% | CPU Limits GPU 45% | CPU Limits GPU 43% | CPU Limits GPU 43% |
| 4K (Ultra HD) | CPU Limits GPU 47% | CPU Limits GPU 45% | CPU Limits GPU 43% | CPU Limits GPU 43% |
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 Core i7-8086K paired with the GeForce RTX 4090 can run Rainbow Six Siege smoothly up to 4k achieving around 164 FPS at Ultra quality. Your GPU is 611% above the recommended specs, and your CPU is 113% above the recommended requirements.
This CPU + GPU combo costs approximately $1827 ($178 CPU + $1649 GPU). Since the CPU is the main limiting factor, investing in a stronger processor will improve your framerates and overall value. For example, the Ryzen 9 9950X is a great upgrade option for around $649 (Rank #4 for value).
For Rainbow Six Siege, upgrading the CPU would have the biggest impact on performance. The Core i7-8086K 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 i7-8086K 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.
