NVIDIA Reflexを有効にすれば手動のFPS上限設定は不要ですか？

Reflex対応ゲームで「On」または「On + Boost」にしている場合、モニターに合わせた最適上限（144Hzで約138 FPSなど）が自動適用されます。ただし、Reflex非対応のゲームでは手動でのFPS上限設定が必須です。

RTSSリミッターはゲーム内リミッターより優れていますか？

適切なゲーム内リミッターやNVIDIA Reflexはレンダリング前に制御するため最も低遅延（約0ms）です。RTSSはWindows上で最も均一で安定したフレームタイムを提供しますが、約1フレーム分の遅延が発生します。

Dynamic Driver Checklist

Actionable step-by-step driver and game configuration for zero tearing and minimal input lag.

0 / 5 Configured

Step 1. Enable G-SYNC in Control Panel Display Setting

Open NVIDIA Control Panel (or modern NVIDIA App) → Display → Set up G-SYNC → Check "Enable G-SYNC, G-SYNC Compatible" → Select "Enable for full screen mode" (or windowed and full screen).

Path: NVIDIA Control Panel > Display > Set up G-SYNC > Enable G-SYNC / G-SYNC Compatible

Step 2. Driver V-Sync (Safety Governor) Driver V-Sync

Go to Manage 3D Settings → Global Settings → Set Vertical Sync to ON. This synchronizes the frame buffer timing and eliminates tearing near the ceiling without adding lag below the cap.

Path: NVIDIA Control Panel > Manage 3D Settings > Global Settings > Vertical Sync = ON

Step 3. Set Max Frame Rate to 158 FPS Frame Rate Cap

Go to Manage 3D Settings → Max Frame Rate → Enter 158. If using an in-game limiter or NVIDIA Reflex, leave this as a universal safety ceiling.

Path: NVIDIA Control Panel > Manage 3D Settings > Max Frame Rate = 158 FPS

Step 4. Set Low Latency Mode to Ultra Low Latency Mode

Set Low Latency Mode to Ultra (or enable NVIDIA Reflex: On + Boost inside individual game settings to sleep render threads at dispatch).

Path: NVIDIA Control Panel > Manage 3D Settings > Low Latency Mode = Ultra

Step 5. In-Game Settings: V-Sync OFF Game Menus

In every game menu, set Vertical Sync: OFF, Triple Buffering: OFF, and select Exclusive Fullscreen or Borderless Windowed to prevent engine queue latency.

Path: In-Game Video Settings > V-Sync = OFF | Triple Buffering = OFF

Input Latency Hierarchy: Where to Apply Your Cap

Comparing input lag penalties, frametime stability, and engine synchronization across capping methods.

Limiter Method	Added Latency	Frame-Time Jitter	Best Used For
In-Game Engine Limiter Active Choice Built directly into the game simulation loop. Offers the absolute lowest possible input latency with zero driver interception overhead, though frame-time consistency varies by game engine.	0.0 - 0.2 ms (Lowest)	Engine dependent	Fast-paced esports titles (Apex, CS2, Overwatch)
NVIDIA Reflex (In-Engine) Active Choice Dynamic render thread governor built into modern game engines. Works at the CPU/GPU dispatch boundary to completely eliminate render queues without requiring manual frame capping.	~0.1 ms (Optimal)	Automatically stabilized	Reflex-supported games (Valorant, Fortnite, Warzone)
RTSS (RivaTuner Stat Server) CPU-level hook with high-precision micro-sleep timers. Produces ruler-flat frametime graphs with zero jitter, at the trade-off of approximately up to one frame of pipeline latency.	~1 frame (~3 - 7 ms) (Pacing Focus)	Near 0.0 ms (Flattest pacing)	AAA cinematic single-player games wanting zero micro-stutter
GPU Driver Limiter (CPL) Universal safety ceiling applied in NVIDIA Control Panel / AMD Adrenalin. Works on every title regardless of engine support, protecting against VRR boundary blowouts.	~1.5 - 2.5 ms (Good)	Good	Set-and-forget universal protection across all PC games

Knowledge Base

Frequently Asked Questions & Technical Mechanics

Deep-dive explanations on VRR physics, driver-level synchronization, presentation models, and 1% low stability.

可変リフレッシュレート（G-Sync/FreeSync）は、フレームレートがモニターの最大周波数未満の場合にのみ動作します。144Hzモニターで144 FPSに達すると、マイクロ秒単位のブレによってVRR上限を超え、テアリングやV-Syncのバッファ遅延（15〜50ms）が発生します。数FPS低く制限することで安全マージン（Δt）を確保できます。

G-Syncが有効かつFPS上限が設定されている場合、ドライバーの垂直同期はバッファではなくフレーム配信の同期制御として機能し、遅延ゼロで画面下部のテアリングを防ぎます。ゲーム内の垂直同期は二重・三重バッファを強制することが多く、重い入力遅延を引き起こします。
