Rainbow Six Siege PC Tweaks Guide to Improve Performance and Graphics

Rainbow Six Siege brings tactical and team-based online play. If you’ve ever played first-person shooters online on the PC, you’ll know that frame-rates are extremely important to become the top-dog.

Rainbow Six Siege PC Tweaks

Rainbow Six Siege is no difference, which is why it’s not unlikely that you’ll spend a bit of time adjusting the settings to get the perfect balance between optimal performance and bearable visuals. This guide will help you do exactly that.

Ambient Occlusion
Ambient Occlusion is a rendering technique that adds contact shadows where two surfaces or objectives meet, or where an object blocks light from reaching another game element.

There are various types of techniques used, and Tom Clancy’s Rainbow Six Siege uses Ubisoft’s custom SSBC or the better Nvidia HBAO+ variant.

Ambient Occlusion is a performance-intensive task, so expect to see drops of around 7-10 fps, depending on what type of AO you choose.

Antialiasing attempts to get rid of the jagged edges of objects and textures in the game. There are various types of antialiasing sampling techniques available, with the most performance-heavy being MSAA.

MSAA 8x can reduce performance by as much as 80 (!) fps on some PCs on 1080p resolution, so it is restricted to hardcore enthusiasts only. If you want to avoid MSAA Hardware antialiasing, simply use the T-AA option in the game.

Lens Effect
Len’s Effect is a nice lighting effect that adds extra bleed to the lights. It has a negligible performance impact, but if you want to ensure maximum visibility on online play, you should turn it off.

LOD Quality
LOD or Level of Detail determines the detail of geometric objects and polygons. In Rainbox Six Siege, it also impacts the visibility and density of foliage and visual flourishes in every level.

The difference between Low and Ultra with decent hardware is minimal, so having it at Ultra is recommended for majority of the users, while those who barely meet the minimum requirements should stick to High/Very High.

Reflection Quality
Rainbow Six Siege uses a reflection technique called Screen Space Reflection, which reflects light off non light-source objects such as walls and floors. This certainly does add to the realism, and in general comes with a cost of around 10 fps between High and Low settings.

Since you’re likely to be too busy in gun-fights, it’s advisable to turn this option off during online play.

Shading Quality
Shading Quality is an option that influence a large set of effects, such as light-material interaction, shading, and subsurface scattering. The performance between Medium and Low is virtually non-existent, and will result in the above-mentioned effects imitating those found on console versions of the game.

The High option has a significant performance impact though, as it adds Relief Mapping that introduces subtle detail. Going with Medium is recommended for most users.

Shadow Quality
Shadow Quality affects the sharpness of shadows rendered and dynamic shadows. On Low settings, dynamic shadows are disabled altogether. Above low, there’s a large increase in shadow definition and quality, but it also comes with greater performance reduction.

There is very little difference between Very High and High settings, so keeping it on High is recommended for medium-to-high-end PCs.

Texture Filtering
Texture filtering determines the sharpness of textures, especially from a distance. This greatly improves the visual quality of the game.

Texture Filtering in Rainbow Six is a little tricky. With Shading Quality set to Medium/Low, it will have negligible impact on performance.

However, if you have Shading Quality on High, using Anisotropic 16x will have a massive impact on performance (up to 16 fps drop) because of its interaction with Relief Mapping. The combination of the two should only be restricted to high-end PCs.

Texture Quality
Texture Quality determines the resolution of the textures used in the game. Higher settings make the textures sharper, more detailed, and clearly visible. In Rainbow Six Siege, Texture Quality has negligible impact on performance, save for the Low setting.

Setting Texture Quality to Low will not only reduce the texture detail and resolution greatly, but will also lower down the geometric detail of objects, which is not recommended unless you’re running an archaic PC.

Zoom-in Depth of Field
Depth of Field adds the cinematic ‘out-of-focus’ effect to surroundings whenever you zoom in with a weapon. However, this effect is extremely subtle in Rainbow Six Siege. It has an average performance impact of 5 frame-rates. Disabling it is recommended if you want a few extra fps.
