Tom Clancy's Rainbow Six Siege — best graphics settings (2026)

Typical impact 0-5% · 2% fps cost

In Tom Clancy's Rainbow Six Siege, we recommend Texture Quality at High (2% fps cost).

Controls the maximum mipmap resolution loaded for surface textures. Higher levels stream larger texture maps (2K/4K) from disk into VRAM via the texture streaming pool. The GPU samples these during fragment shading using the currently bound sampler state. The FPS cost is minimal when VRAM is sufficient because texture fetch latency is hidden by the cache hierarchy, but exceeding VRAM capacity triggers page-faulting and hitching as textures are swapped between system RAM and VRAM.

In Tom Clancy's Rainbow Six Siege: AnvilNext 2.0 streams surface textures into a managed VRAM pool. On Ultra, 4K albedo, normal, and roughness maps are loaded for destructible wall plaster, wood panelling, and operator gear on maps like Consulate and Oregon. The jump from High to Ultra is almost entirely VRAM-bound — if you have 4 GB+ you will see no frame-time cost, but exceeding the pool triggers stutters. Medium is a safe competitive floor with minimal visual regression in fast-paced matches.

Typical impact 0-2% · 2% fps cost

In Tom Clancy's Rainbow Six Siege, we recommend Texture Filtering at Anisotropic 16x (2% fps cost).

Determines the sampling method when textures are viewed at oblique angles. Bilinear samples a single mip; trilinear blends between two mip levels to remove seams. Anisotropic filtering takes multiple samples along the axis of greatest compression, preserving sharpness on surfaces like roads and floors seen at steep angles. Modern GPUs have dedicated anisotropic filtering hardware in the texture units, making even 16x virtually free.

In Tom Clancy's Rainbow Six Siege: Siege's maps feature many floor-level sightlines across tiled floors and corridors — exactly where anisotropic filtering matters. Linear filtering produces visible shimmer on long hallways in maps like Chalet. Anisotropic 16x eliminates that with essentially zero frame-time penalty on modern GPUs since the texture unit hardware handles it without competing with shader ALU work. There is no reason to run below 16x in this engine.

Typical impact 8-25% · 6% fps cost

In Tom Clancy's Rainbow Six Siege, we recommend Shadow Quality at Medium (6% fps cost).

Controls shadow map resolution, filtering method, and cascade count for dynamic shadows. The engine renders the scene from each light source perspective into depth-only shadow map textures. Higher settings increase shadow map resolution (1024 to 4096 texels), add more cascaded shadow map splits for the directional light (improving near-field resolution), and enable softer PCF or PCSS filtering which requires more depth comparison samples per pixel during the lighting pass.

In Tom Clancy's Rainbow Six Siege: Shadow Quality in Siege controls the directional and local shadow map resolution plus cascade count across AnvilNext's deferred shadow pass. Dropping from High to Medium reduces shadow map resolution and eliminates one cascade, producing a measurable 12–18% FPS improvement. Off removes all dynamic shadows entirely — useful on very low-end hardware, but operators become hard to distinguish against similar-coloured surfaces in darker maps like Theme Park.

Typical impact 3-20% · 5% fps cost

In Tom Clancy's Rainbow Six Siege, we recommend Reflection Quality at Medium (5% fps cost).

Controls the method and fidelity of surface reflections. Low settings use pre-baked cubemap probes — a single texture lookup per pixel. Medium enables screen-space reflections (SSR) that ray-march through the depth buffer to find reflected geometry. High uses higher-resolution SSR with more march steps. Ultra may enable planar reflections (re-rendering the scene from a mirrored viewpoint) or RT reflections (hardware-accelerated rays). The cost escalation from cubemaps to SSR to RT is dramatic — cubemaps are nearly free, SSR costs 3-8%, and RT reflections cost 15-25%.

In Tom Clancy's Rainbow Six Siege: AnvilNext handles reflections in Siege through a combination of screen-space reflections (SSR) and baked cubemap probes. High enables full SSR ray-marching across reflective surfaces like the polished floors of Bank's lobby and the wet exterior of Border. Medium falls back to mixed SSR at lower march depth plus probes. Off uses only static probes. SSR at High adds a visible frame-time cost due to the depth-buffer ray march, making Medium the best quality-per-frame-time option for competitive play.

Typical impact 3-12% · 3% fps cost

In Tom Clancy's Rainbow Six Siege, we recommend Ambient Occlusion at SSAO (3% fps cost).

Computes soft shadowing in crevices and where surfaces meet by estimating how much ambient light is occluded at each pixel. SSAO samples the depth buffer in a hemisphere around each pixel, testing for nearby occluders. HBAO+ uses ray-marching along the depth buffer horizon. GTAO uses a multi-directional horizon search with cosine-weighted integration for physically correct results. Each method runs as a fullscreen compute or pixel shader pass — higher quality modes increase sample count from 4 (SSAO) to 32+ (GTAO Ultra), directly scaling the per-pixel ALU cost.

In Tom Clancy's Rainbow Six Siege: Siege's HBAO+ implementation adds horizon-based occlusion to contact edges — the underside of desks, doorframe junctions, and barricade seams across indoor environments. SSAO uses fewer depth taps and produces softer, less accurate shadowing. HBAO+ costs 4–8% more frame time than SSAO due to the directional horizon search. For a game where spotting operators in corners is critical, both modes can slightly obscure dark areas; many competitive players set this to Off to keep wall surfaces evenly lit.

Typical impact 3-12% · 4% fps cost

In Tom Clancy's Rainbow Six Siege, we recommend Level of Detail (LOD) at High (4% fps cost).

Governs the distance thresholds at which objects transition between LOD tiers. The engine uses screen-space projected size or distance-based heuristics to swap between high-poly and simplified meshes. Higher settings push these transition distances further, keeping detailed geometry on screen longer. This increases total triangle count, draw calls, and vertex buffer memory. In UE5 titles using Nanite, this controls the aggressiveness of the virtual geometry streaming system.

In Tom Clancy's Rainbow Six Siege: In Siege's enclosed maps, LOD transitions are rarely visible — the maximum view distance across most areas is 30–40 metres. High/Ultra LOD settings maintain full-poly operator models and prop geometry at distances that never appear in practice. Medium or High is the effective ceiling where visual quality is indistinguishable from Ultra in normal gameplay. LOD distance matters more in exterior sections of maps like Villa or Coastline, where distant foliage and prop geometry can pop.

Typical impact 3-10% · 4% fps cost

In Tom Clancy's Rainbow Six Siege, we recommend Shading Quality at Medium (4% fps cost).

Controls the complexity of the BRDF (Bidirectional Reflectance Distribution Function) evaluation in the lighting pass. In AnvilNext 2.0 (Rainbow Six Siege), lower settings use a simplified single-lobe GGX specular model with reduced material parameter sampling. Higher settings enable the full multi-lobe PBR model with separate diffuse and specular components, clear-coat layer evaluation, anisotropic specular direction, and additional texture fetches for cavity maps and detail normals. Each additional lobe adds ALU instructions, increasing per-pixel instruction count by 20-40% between Low and Ultra.

In Tom Clancy's Rainbow Six Siege: AnvilNext shading controls PBR material complexity. Low uses simplified BRDF — 8% FPS gain with minimal visual loss.

Typical impact 2-15% · 3% fps cost

In Tom Clancy's Rainbow Six Siege, we recommend Anti-Aliasing at TAA (3% fps cost).

Smooths jagged edges (aliasing) on geometric boundaries. FXAA is a single-pass edge-detection blur — cheap but softens the image. TAA accumulates multiple frames using motion vectors, sampling sub-pixel jitter offsets to reconstruct smoother edges — moderate cost with potential ghosting. SMAA uses pattern-matching edge detection with a more intelligent blend. MSAA runs the rasterizer at 2x/4x the sample count, evaluating coverage for each triangle edge — expensive because it multiplies ROP work and render target memory, but produces sharp geometry edges without blur.

In Tom Clancy's Rainbow Six Siege: T-AA (temporal anti-aliasing) in AnvilNext accumulates sub-pixel jitter across frames using motion vectors — at base T-AA the cost is moderate with acceptable ghosting on fast rope traversals. T-AA + 2x and T-AA + 4x apply additional super-sampling on top of temporal accumulation, producing the sharpest image but costing 15–30% frame time. FXAA is a single-pass edge blur — cheap but noticeably softens fine geometry like barbed wire on Kafe. For competitive play, FXAA or Off with a sharpening filter is common to preserve edge clarity on operator outlines.

Typical impact 15-60% · no measurable cost

In Tom Clancy's Rainbow Six Siege, we recommend Render Resolution at 100% (no measurable cost).

Controls the internal 3D rendering resolution as a percentage of the display output resolution, independent of any AI upscaling (DLSS/FSR). The engine renders the scene at the specified fraction of native resolution — this scales the render target dimensions, directly reducing the number of fragment shader invocations, texture fetches, and ROP output pixels. A 50% render scale produces 25% of the total pixels of native resolution. The reduced-resolution image is then upscaled to display resolution using a simple bilinear or bicubic filter. This is the most direct FPS/quality tradeoff available.

In Tom Clancy's Rainbow Six Siege: Siege supports resolution scaling independent of DLSS/FSR. 80% render scale at 1440p looks similar to native 1080p with much better HUD clarity.

Typical impact 2-6% · 2% fps cost

In Tom Clancy's Rainbow Six Siege, we recommend Lens Effects at On (2% fps cost).

Controls camera lens simulation effects including lens flare, anamorphic streaks, and scope refraction. Lens flare is computed by tracing ghost reflections through a virtual lens system — bright pixels generate reflection sprites placed along the line from the bright source through the screen center. Anamorphic streaks use a directional bloom pass (horizontal-only blur of bright pixels). Scope refraction renders a warped view through the scope lens using a distortion shader. In tactical shooters like R6 Siege, these effects are visible during ADS and can impact visual clarity.

In Tom Clancy's Rainbow Six Siege: Includes lens flare and scope refraction. Most pros disable for clarity during ADS (aim down sights).

Typical impact 0-3% · 1% fps cost

In Tom Clancy's Rainbow Six Siege, we recommend Bloom at On (1% fps cost).

Produces a glow around bright light sources by extracting pixels above a brightness threshold and blurring them back into the scene. The implementation uses a bright-pass filter, followed by progressive downsampling with Gaussian blur at each mip level (4-6 levels), then re-compositing the blurred mips into the original image. The multi-pass nature means multiple fullscreen reads/writes, but each successive pass operates on a smaller buffer. Total cost is modest due to separable Gaussian implementation.

In Tom Clancy's Rainbow Six Siege: Bloom in Siege brightens windows, spotlights, and exterior sky sources by extracting above-threshold pixels and compositing multi-stage Gaussian blurs back into the scene. On maps like Coastline or House with strong outdoor lighting, bloom can wash out visibility around bright window openings — a tactical liability. Disabling it removes the bright-pass and blur passes entirely, recovering 1–2% frame time and, more usefully, improving visual clarity in high-contrast indoor-outdoor transitions where operators may be silhouetted.

Typical impact 2-8% · 2% fps cost

In Tom Clancy's Rainbow Six Siege, we recommend Depth of Field at On (2% fps cost).

Simulates camera lens focus by blurring pixels based on their distance from a focal plane. The depth buffer is sampled to determine each pixel's circle of confusion (CoC). A Gaussian or bokeh blur is applied with kernel size proportional to CoC. Higher quality modes use physically-based hexagonal or circular bokeh shapes via a gather pass. Cinematic mode may use separate near-field and far-field blur with smooth transitions. The cost scales with maximum CoC radius — large blur kernels require 32+ texture taps per pixel.

In Tom Clancy's Rainbow Six Siege: Depth of Field in Siege applies a CoC-based blur during the cinematic operator-select and kill-cam sequences, not during live gameplay. It is not applied to the player camera during active rounds. Disabling it eliminates the blur passes in those transitional screens with negligible in-round FPS benefit. The setting is largely a preference choice — On provides a polished cinematic feel during replays, Off keeps every screen uniformly sharp.

Typical impact -30-80% · no measurable cost

In Tom Clancy's Rainbow Six Siege, the recommended preset leaves NVIDIA DLSS off — little visual loss for the frames it returns.

Deep Learning Super Sampling — NVIDIA's AI-based temporal upscaling that runs on dedicated Tensor Core hardware. The engine renders at a lower internal resolution and feeds the reduced-resolution frame, motion vectors, and depth buffer to a neural network that reconstructs a high-resolution output. DLSS 3+ adds optical flow-based frame generation on Ada/Blackwell architectures. The FPS gain comes from rendering fewer pixels — Quality mode renders ~67% of native pixels, Performance ~50%, Ultra Performance ~33%.
