To improve Rainbow Six Siege performance on a low-end PC or laptop, first compare your hardware with Ubisoft’s current minimum requirements, then identify whether the CPU or GPU is limiting frame rate. Lower resolution or graphics quality one setting at a time and compare in the same game conditions. These steps can help diagnose the problem, but no setting or upgrade guarantees a specific FPS increase.
Check whether your PC meets Ubisoft’s current minimum
Ubisoft lists its current minimum configuration for a 1080p/60 target as follows. These are published requirements, not a guarantee that every system will sustain 60 FPS in every match or mode.
| Component | Ubisoft minimum |
|---|---|
| Processor | AMD Ryzen 3 3100 or Intel Core i3-8100 |
| Memory | 8 GB RAM |
| Graphics | NVIDIA GTX 1650 4 GB, AMD RX 5500 XT 4 GB, or Intel Arc A380 6 GB, or better |
| Operating system | Windows 10 or 11, 64-bit |
| Graphics API | DirectX 12 |
| Storage | 65 GB SSD |
Ubisoft’s current PC system requirements also caution that laptop video-card models may work if their performance is similar to the listed minimum. A laptop GPU with a familiar name is not necessarily equivalent to its desktop counterpart; check the exact mobile GPU model and system configuration.
Account for game mode and target
Ubisoft’s May 18, 2025 Siege X specifications list 16 GB RAM in recommended high configurations. At the recommended 1080p high target, Ubisoft specifies 120 FPS for Core Siege and 60 FPS for Dual Front. These are different mode targets, not measured results or a promise that a given PC will reach them. Compare performance in the mode you actually play rather than assuming one FPS figure applies everywhere. See Ubisoft’s Siege X PC and console specifications.

Record a baseline before changing settings
Write down your CPU, exact GPU model (including whether it is a laptop variant), installed RAM, display resolution, and a representative in-game frame rate. Note the game mode and where you measured it. This gives you a before-and-after comparison and helps separate a settings problem from hardware that is below the published baseline.
Use the same resolution, mode, and comparable gameplay conditions for each check. Change one setting at a time; if you change several together, you will not know which change affected performance.

Work out whether the CPU or GPU is the limit
Frame rate depends on both the processor and graphics card. Ubisoft’s January 2020 technical explanation says they work in parallel and that the slower one determines the maximum frame rate. Lowering image quality can reduce GPU workload, but it will not automatically fix a CPU bottleneck. If reducing graphics quality or resolution makes little difference, that is a reason to investigate CPU, memory, or other system limits rather than keep lowering every visual setting.
Use this as a diagnostic, not a definitive benchmark: compare your baseline with a lower resolution or lower GPU-heavy quality option, then restore or retain changes based on the result. Ubisoft’s explanation appears in its historical Vulkan API Testing on Live PC article, published January 27, 2020.

- Whisper-Quiet Operation: Enjoy a noise-free and interference-free environment with super quiet fans, allowing you to focus on your work or entertainment without distractions.
- Enhanced Cooling Performance: The laptop cooling pad features 5 built-in fans (big fan: 4.72-inch, small fans: 2.76-inch), all with blue LEDs. 2 On/Off switches enable simultaneous control of all 5 fans and LEDs. Simply press the switch to select 1 fan working, 4 fans working, or all 5 working together.
- Dual USB Hub: With a built-in dual USB hub, the laptop fan enables you to connect additional USB devices to your laptop, providing extra connectivity options for your peripherals. Warm tips: The packaged cable is a USB-to-USB connection. Type C connection devices require a Type C to USB adapter.
- Ergonomic Design: The laptop cooling stand also serves as an ergonomic stand, offering 6 adjustable height settings that enable you to customize the angle for optimal comfort during gaming, movie watching, or working for extended periods. Ideal gift for both the back-to-school season and Father's Day.
- Secure and Universal Compatibility: Designed with 2 stoppers on the front surface, this laptop cooler prevents laptops from slipping and keeps 12-17 inch laptops—including Apple Macbook Pro Air, HP, Alienware, Dell, ASUS, and more—cool and secure during use.
Reduce rendering workload carefully
- Lower resolution for a comparison. Test a lower display resolution and check whether frame rate improves under the same gameplay conditions. If it does, graphics workload is likely part of the constraint; the trade-off is a less sharp image.
- Reduce graphics quality one option at a time. Start with options that affect visual rendering workload, compare the result, and keep only changes that help without making the image unacceptable. No authoritative current source establishes a universal best preset or a fixed FPS gain for individual settings.
- Watch for stutter as well as average FPS. If performance includes hitching, not just a low frame rate, check whether texture quality and resolution are too demanding for available video memory (VRAM). Lowering them is a reasonable diagnostic when VRAM pressure is suspected.
Ubisoft’s warning about memory oversubscription and stutter or crashes comes from its 2020 Vulkan guidance, which identifies texture quality and resolution as important memory factors. Treat that as historical technical context, not proof of how every current Siege X renderer behaves.
Keep drivers and graphics API advice current
Keeping graphics drivers current is ordinary maintenance, but a driver update is not a guaranteed FPS fix. Ubisoft’s current minimum requirements list DirectX 12. The available official sources do not confirm the current renderer choices for Siege X, so do not switch APIs based on old advice alone.

For Intel Arc discrete graphics specifically, Intel’s article last reviewed December 17, 2024, advised driver version 31.0.101.5448 or newer and Vulkan troubleshooting. That is dated, Arc-specific guidance—not a universal instruction for all GPUs or confirmation that Vulkan is a current Siege X launch option. See Intel’s Arc Vulkan troubleshooting article.
Independent reader supportYour contribution helps us test, update, and keep practical guides available for everyone.Consider RAM only after checking capacity and upgradeability
If your laptop has 8 GB RAM, memory pressure may be worth investigating: Ubisoft lists 8 GB in its current minimum configuration and 16 GB in the recommended high configurations published in 2025. A compatible move to 16 GB is a capacity to consider, not a guaranteed FPS upgrade. Check the laptop’s exact model for upgradeability and compatible memory before buying; some laptops do not allow a straightforward RAM upgrade.

Avoid risky or unsupported “boost” fixes
The cited sources do not establish FPS gains from disabling Windows services, editing the registry, or using third-party “FPS booster” utilities. Avoid treating such changes as proven fixes. Likewise, the available official evidence does not support a universal settings list with promised gains. Use measured, reversible changes and keep a record of what you changed.
