How to improve FPS in Rainbow Six Siege (PC)
Rainbow Six Siege uses Ubisoft's AnvilNext engine and is one of the most popular tactical shooters on the market. The game is extraordinarily well-optimized for competitive play — it's possible to reach 300+ FPS on mid-range hardware with the right configuration. The most important and unique setting in Siege is Render Scaling: Ubisoft recommends 85-90% as the optimal performance-to-image-quality balance. LOD Quality and Shadow Quality complete the main optimizations.
This is what you'd gain with a NVIDIA RTX 3050
Calculations based on our FPS model combined with the % gain of each setting (measured in public benchmarks). Calculate your exact FPS with your own hardware →
1. Quick wins (no visual loss)
Start here. Each one adds a little, but together they give +20% free FPS.
V-Sync
V-Sync Off is mandatory in a competitive tactical shooter. The added latency can cost duels in Siege.
Motion Blur
Motion Blur Off in any competitive shooter. Confuses in combat and adds GPU cost.
Anti-Aliasing
TAA in Siege adds ghosting and blurring. FXAA is the competitive balance: decent anti-aliasing at minimal cost. Off for maximum FPS.
Depth of Field
DoF can make battlefield reading harder during breach/rappel. Always off in competitive.
2. Medium impact settings
Here's where most of the FPS is. Minor visual impact, major performance impact.
Render Scaling
Render Scaling at 85-90% is Siege's most recommended setting. It renders slightly below native resolution and upscales — gives a very notable FPS gain with nearly imperceptible sharpness loss in competitive practice. At 75% or lower, visual degradation is noticeable.
LOD Quality
LOD Quality Ultra in Siege has significant GPU cost. High keeps models at maximum quality at normal combat distances.
Shadow Quality
Shadows in Siege are important for enemy detection (seeing shadows under doors provides tactical info). Low gives functional shadows with great GPU savings. Medium is the balance for those wanting acceptable quality.
Texture Quality
Ultra textures in Siege use additional VRAM with no noticeable visual difference during interior combat. High is the optimal point.
Ambient Occlusion
Ambient Occlusion in Siege has real cost. Off in competitive settings to maximize FPS.
3. Upscaling (DLSS / FSR / XeSS)
The biggest gain in the game. Compatible with almost any modern GPU.
Render Scaling interno (85-90%)
+25% FPSSiege has its own internal resolution scaling system (Render Scaling). 85-90% is the officially recommended optimal point — gives notable FPS gain with minimal visual loss.
DLSS (NVIDIA RTX, añadido en 2022)
+22% FPSSiege added DLSS support in 2022. Quality offers good image. For competitive play, combining DLSS with Render Scaling at 100% is the best RTX option.
4. Tips by GPU
NVIDIA
- •NVIDIA Reflex is available in Siege: always enable 'On + Boost' to minimize input latency in tactical duels.
- •DLSS Quality + Render Scaling 100% is the optimal RTX configuration: near-native image with FPS gains.
- •Low Latency Mode 'Ultra' in NVIDIA Control Panel for Siege — real benefit in 1v1.
AMD
- •Render Scaling at 85-90% is the best 'upscaling' option for AMD in Siege — works for all GPUs.
- •Anti-Lag available to reduce input latency.
- •Siege is well-optimized for AMD — no significant disadvantage versus NVIDIA.
Sistema
- •High Performance power plan in Windows: Siege is CPU-intensive in duels — the power plan can give 5-10% FPS.
- •Lower desktop resolution or use exclusive fullscreen mode to avoid Windows compositor overhead.
- •Siege in exclusive fullscreen mode (not borderless windowed) gives the lowest possible response times.
5. Known game issues
TAA ghosting on moving operators
TAA anti-aliasing in Siege causes ghosting (blurry trail) on moving operators. The solution is switching to FXAA or disabling AA for a cleaner game.
FPS drops on maps with many windows and reflections
Some Siege maps with many reflective surfaces (Clubhouse, Bank) have lower FPS than others. Shadow Quality Medium and LOD Quality High mitigate this effect.
Occasional stuttering on the first map of a session
The first map of each gaming session may have stuttering while shaders and textures are cached. It normalizes in subsequent rounds.
