Rainbow Six Siege X: best PC settings (2026)

The best Rainbow Six Siege X PC settings keep LOD Quality, Texture Filtering and Shadow Quality at medium or higher, so you can see heads and shadows, and turn off what only adds polish: Lens Effects, Zoom-In Depth of Field, Ambient Occlusion and high reflections. Keep Render Scaling at 100, VSync off and, on a GeForce card, NVIDIA Reflex Low Latency on. The rest depends on your PC, and it pays to measure before and after you change anything.

The names below match the menu with the game in English. If an old guide tells you to pick Vulkan or DirectX 11, skip it: since season Y10S1 (March 2025), Ubisoft has kept a single API on PC, DirectX 12, and the Siege X requirements list DirectX 12 for every tier.

Recommended settings

• Display Mode: Fullscreen. It gives the game full control of the screen; use borderless only if you switch windows a lot.
• Refresh Rate: your monitor’s rate. Left at 60 Hz, a 144 Hz or faster monitor behaves like a 60 Hz one.
• VSync: Off. It holds each frame until the next screen refresh and adds delay to your clicks.
• Field of View: 90 is the most common pick. Lower values make enemies bigger on screen but show less of the sides.
• Texture Quality: the highest that fits in your graphics card’s memory. Textures weigh on video memory more than on FPS. The Ultra level needs the high-resolution texture pack, downloaded separately.
• Texture Filtering: Anisotropic 4x or higher. It costs little and keeps floors and angled walls sharp; Linear blurs anything far away.
• LOD Quality: High or above. It matters most for visibility: at low levels, distant players lose detail and heads turn into a few polygons.
• Shading Quality: Low or Medium. It changes little on screen and costs performance.
• Shadow Quality: Medium. On Low the game removes dynamic shadows, and the shadow of someone coming through a door no longer shows.
• Reflection Quality: Low. It’s one of the most expensive options in the menu and doesn’t help you see anyone.
• VFX Quality: Low or Medium. It controls particles, decals and debris; above that it’s cosmetic.
• Ambient Occlusion: Off. Corner shading (SSBC and SSBC+) is expensive and darkens indoor areas.
• Lens Effects: Off. Bloom and lens flare create glare near windows and explosions.
• Zoom-In Depth of Field: Off. It blurs the edges of the screen when you aim.
• Anti-Aliasing: T-AA, with T-AA Sharpness around 50. It’s the mode that unlocks upscaling (NVIDIA DLSS, AMD FSR 1.0 and AMD FSR 2.0).
• Render Scaling: 100, with Adaptive Render Scaling Target FPS at 0 (off). Adaptive scaling changes sharpness in the middle of a round.
• NVIDIA Reflex Low Latency: On + Boost, on a GeForce card.

What to lower first, from most to least expensive

If FPS isn’t where you want it, lower things in this order and test a match or the shooting range after each step. That way you know what actually changed on your PC.

1. 1Reflection Quality to Low. In a 2025 Siege X test, it was the most expensive option.
2. 2Ambient Occlusion to Off.
3. 3Lens Effects and Zoom-In Depth of Field to Off.
4. 4VFX Quality and Shading Quality to Low.
5. 5Shadow Quality to Medium, if it was higher.
6. 6Upscaling: with Anti-Aliasing on T-AA, turn on NVIDIA DLSS (GeForce RTX cards) or AMD FSR 2.0 in a quality mode. It keeps more sharpness than lowering Render Scaling, which makes the image very blurry.
7. 7Texture Quality last, and only if your card’s memory is maxed out.

What to keep high to spot enemies

Three options are worth the cost even on a modest PC. LOD Quality keeps the shape of distant players. Texture Filtering above Linear keeps angled surfaces sharp, like a hallway floor. Shadow Quality on Medium shows the shadow of someone walking up to a door or a staircase. What goes without a second thought is anything that adds glare or blur in front of your crosshair: Lens Effects and Zoom-In Depth of Field.

FPS limit, Reflex and latency

Reflex removes the frame queue between the CPU and the graphics card when the GPU is maxed out, which shortens the time between your click and the image. It doesn’t raise FPS. With VSync off and Reflex on, most players leave FPS uncapped. If it swings far above your monitor’s refresh rate, a fixed cap slightly above it usually makes frame time more even. On AMD or Intel cards Reflex doesn’t show up, and what matters is VSync off and steady FPS.

Changed several options at once? Compare the average and the 1% low on the same stretch before and after. The slow tail is what you feel as stutter, not the average.
