How to Improve Your Rainbow Six Siege X FPS

In Rainbow Six Siege X FPS, it is a big part of how to get the best performance out of your own game. With the game being about such small details and even finer margins, your FPS can impact how well you perform. Stability is key, not to mention getting the highest FPS as you can. In the most intense moments, it can be completely key.

In this guide, we’ll go over the things you can do to not only improve your Rainbow Six Siege X FPS but also maintain a smooth performance in-game, especially if you want to rank up quicker.

Why is Your Rainbow Six Siege X FPS Low

Low FPS can be caused by a number of problems, out-of-date drivers, recent Windows updates, new Siege X patches, or ageing hardware. These are some options if you’re not getting an ideal FPS:

Update Your Graphics Drivers

The first and simplest fix is to update your Nvidia or AMD graphics drivers. Drivers for both are released fairly often, and even older titles such as Siege will often have performance improvements in new software updates.

Head to the Nvidia or AMD software and check for updates. It’s worth also noting that “known issues” might be listed for Siege X in the notes section. If they are present, it might be an idea to roll back your drivers instead.

Changing Your Video Settings

In Siege X, there are a number of settings you can change that’ll have the largest impact on your FPS. From Shadows and reflections, to anti-aliasing and bloom.

Use the settings below as a benchmark to move forward. It’s also very much advised to use the built-in Siege X benchmark tool. It’s a big help to have tools like this if you want to perform at a Rainbow Six esports level. These are some of the most important settings:

• Shadow Quality – Low
• Ambient Occlusion – Off
• Reflection Quality – Low
• Lens Effects – Off
• Bloom – Off
• Level of Detail – Low or Medium
• Anti-Aliasing – TAA or SMAA

These settings are the ones that will impact Rainbow Six Siege X FPS the most without any tangible loss. The ones below will also impact, but will also lead to a loss in the fidelity of the game and may hurt visibility.

Optimal Settings Example

Texture Quality – Set this to Low or Medium depending on your GPU. Lower textures use less VRAM and keep the game stable

Texture Filtering – Use Linear or Anisotropic 2x. It gives a clear look without costing much performance

Level of Detail Quality – Strangely, Ultra is often the best choice. It helps you see enemies further away and doesn’t hit FPS as hard as you’d expect

Shading Quality – Keep this on Low or Medium. It removes extra lighting that does nothing for gameplay

Shadow Quality – Medium is the sweet spot. Low removes some helpful visual clues, while High eats up frames

Reflection Quality – Set this to Off or Low. Reflections drain GPU power for no real benefit

Ambient Occlusion – Turn this Off. It barely adds anything to the image and costs too much performance

Lens Effects & Bloom – Switch both Off. They only add visual clutter and can increase input delay

Anti-Aliasing – FXAA is fine if you want a little smoothing. Turning AA off gives the best FPS, though the image will look sharper and more jagged

FOV – Keep this to your preference; a higher FOV gives more vision but slightly lowers FPS

Resolution – Running below native gives a big boost, but it can look blurry

Sharpening – Low or Off, it helps clarity but adds cost

HUD / Accessibility Effects – Turn off camera shake and extra animations

Things to Enable and Turn Off for Better Rainbow Six Siege X FPS

Using Fullscreen

Nowadays, it’s common for people to run games in windowed mode or borderless windows. However, fullscreen mode brings performance improvements as it focuses the PC on that application. By giving your display full control of the game, you can help with smoother input and frame rates.

Fullscreen Optimisation

Head to the Rainbow Six Siege X.exe file and head to – Properties – Compatibility – Disable fullscreen optimisations. While it seems like a good thing, it actually can cause issues; it has also been known to cause crashing.

Change Render Scaling

The render scaling setting is a big setting that you can change. At 100, you are making the game render at the full resolution. If you are using a resolution above 1080p, then reducing it to 90, 80, etc can help to boost your performance. This will impact how the game looks, so be careful how low you go.

Turn Off VSync

VSync limits your Rainbow Six Siege X FPS FPS to that of your refresh rate, but in turn can add input delay. By turning it off, you will see less screen tearing. Instead, use Nvidia Fast Sync or AMD Enhanced Sync instead in your driver software.

Close background applications

Close any programs in your Task Manager that might be using a lot of CPU and RAM.

Enable NVIDIA Reflex or AMD Anti-Lag

Both of these options will reduce the input latency and make aiming feel smoother, which won’t improve your FPS but make it better regardless.

Launcher Options

You can add launch options in Steam to force certain settings. Right-click Siege X → Properties → Launch Options and add:
-high -vulkan -con_enable 1 -console

You can replace vulkan with DirectX 11 instead, as vulkan doesn’t play well on all systems.

Benchmarks

Use the built-in Siege X benchmark tool to help find your ideal settings. From here, you can tweak them from a baseline.

Verify Game Files

On both Steam and Ubisoft Connect, you can verify game files:

• On Steam, right-click Siege X → Properties → Installed Files → Verify integrity
• On Ubisoft Connect → Properties → Verify Files.

All of these things should make an impact on your Rainbow Six Siege X FPS and give you a much better and smoother performance.
