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.
At 1440p ultra, the Xeon W-1350 sets the ceiling at about 186 FPS, while the GeForce RTX 4090 could reach 450 FPS. In this scenario, the CPU limits the GPU potential by 59% (FPS gap: 264 FPS). Overall distribution: CPU limits 12/12 cells, GPU limits 0/12, balanced 0/12.
Your Xeon W-1350 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 33% | CPU Limits GPU 26% | CPU Limits GPU 34% | CPU Limits GPU 44% |
| 1440p (2K QHD) | CPU Limits GPU 46% | CPU Limits GPU 48% | CPU Limits GPU 49% | CPU Limits GPU 59% |
| 4K (Ultra HD) | CPU Limits GPU 39% | CPU Limits GPU 40% | CPU Limits GPU 49% | CPU Limits GPU 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, not generic utilization heuristics.

The Xeon W-1350 + GeForce RTX 4090 pairing runs this title with CPU utilization between 23% and 100% and GPU utilization between 22% and 81%. Xeon W-1350 reaches high load in heavier scenarios, while GeForce RTX 4090 is utilized efficiently without persistent saturation. As resolution scales, average GPU load rises from 54% at 1080p to 57% at 4K, while CPU averages move from 80% to 72%.
From a utilization perspective, this is a CPU-heavy load profile. At 1080p (Full HD) Low, the Xeon W-1350 reaches 98% average load (95-100%), while the GeForce RTX 4090 remains comparatively lower at 30% (22-37%). This points to heavier CPU-side frame preparation work, but utilization alone does not define the FPS limiter.
At 1080p, averages sit around CPU 80% and GPU 54%. At 1440p, that shifts to CPU 72% and GPU 57%, and at 4K it reaches CPU 72% and GPU 57%. 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 48% (23-74%) and GPU 80% (78-81%), which keeps GeForce RTX 4090 well utilized without constant max-out behavior while Xeon W-1350 remains stable for consistent frame delivery.
Current utilization does not show an urgent upgrade requirement for either component; the Xeon W-1350 and GeForce RTX 4090 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 Xeon W-1350 paired with the GeForce RTX 4090 can run Rainbow Six Siege smoothly up to 4k achieving around 149 FPS at Ultra quality. Your GPU is 611% above the recommended specs, and your CPU is 184% above the recommended requirements.
This CPU + GPU combo costs approximately $1904 ($255 CPU (Rank #98 Value) + $1649 GPU (Rank #77 Value)). Since the CPU is the main limiting factor, investing in a stronger processor will improve your framerates and overall value. For example, the Xeon Platinum 8454H is a great upgrade option for around $6540 (Rank #1 for value).
For Rainbow Six Siege, upgrading the CPU would have the biggest impact on performance. The Xeon W-1350 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 Xeon W-1350 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.
