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
Performance Report
At 1080p, performance runs at around 31 FPS. At 1440p, frame rates range from 25 to 31 FPS. At 4K, frame rates range from 10 to 19 FPS.
The GeForce RTX 4090 is 611% above the recommended GPU (GeForce GTX 670) for Rainbow Six Siege. The Pentium Dual Core T4300 is 46% below minimum CPU requirement.
At lower resolutions (all 1080p settings, 1440p (low/medium/high)), the Pentium Dual Core T4300 sets the FPS ceiling. As graphical load increases at (4k (high/ultra)), the GeForce RTX 4090 becomes the FPS-limiting side. The FPS ceiling is closely matched at 1440p ultra, 4k (low/medium).
Approximated average price on current market:
Combo price: $1748. At 1080p Ultra, this combo delivers 31 FPS, equivalent to 0.02 FPS per dollar.

This section is based on estimated CPU/GPU FPS ceilings, not utilization percentages.
At 1080p low, the Pentium Dual Core T4300 sets the ceiling at about 31 FPS, while the GeForce RTX 4090 could reach 113 FPS. In this scenario, the CPU limits the GPU potential by 73% (FPS gap: 82 FPS). Overall distribution: CPU limits 7/12 cells, GPU limits 3/12, balanced 2/12.
Your Pentium Dual Core T4300 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 73% | CPU Limits GPU 66% | CPU Limits GPU 61% | CPU Limits GPU 48% |
| 1440p (2K QHD) | CPU Limits GPU 55% | CPU Limits GPU 42% | CPU Limits GPU 34% | Balanced |
| 4K (Ultra HD) | Balanced | GPU Limits CPU 26% | GPU Limits CPU 39% | GPU Limits CPU 48% |
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 Pentium Dual Core T4300 and GeForce RTX 4090 will struggle to run Rainbow Six Siege at smooth framerates. At 1080p Ultra, you can expect around 31 FPS which is classified as "playable". Consider lowering settings or upgrading your hardware.
This CPU + GPU combo costs approximately $1748 ($99 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 7845HX is a great upgrade option (Rank #1 for value).
For Rainbow Six Siege, upgrading the CPU would have the biggest impact on performance. The Pentium Dual Core T4300 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. GPU fully utilized at: 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 hardware falls below the minimum requirements for this game, which may result in poor performance.
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.
