To fix stuttering in Ready or Not, first cap your frame rate, reduce CPU-heavy effects and texture-streaming pressure, allow shaders to compile, and then test each change in the same demanding mission area.

1. Identify what kind of stutter you have

Different symptoms require different fixes. A low average frame rate usually means the GPU is overloaded; brief freezes when entering rooms often point to shader compilation or asset streaming; uneven motion despite a high frame counter is usually a frame-pacing problem. Ready or Not can become especially CPU-limited when several AI suspects, civilians, doors, lights, and physics objects are active at once.

What you notice Likely cause First change to try
Short hitching when entering a new area Shader compilation or texture/asset streaming Let shaders finish compiling; lower texture streaming pressure
Stutter during raids with many NPCs CPU simulation, AI, lighting, or draw-call load Lower view distance, shadows, and effects; close background CPU tasks
GPU usage stays near 99% GPU-bound rendering Lower resolution, resolution scale, shadows, or post-processing
GPU usage is low while frame time spikes CPU bottleneck, streaming, or background software Use a frame cap and reduce CPU-heavy settings rather than only lowering resolution
High FPS but visibly uneven movement Unstable frame pacing Cap FPS below your display refresh rate and use one synchronization method

2. Apply a stable baseline before changing everything

Use these settings as a starting point on a typical gaming PC with 16 GB or more system memory and a dedicated GPU with at least 8 GB of VRAM:

  • Display mode: Fullscreen or the game’s exclusive fullscreen option, if available.
  • Resolution: your monitor’s native resolution.
  • Resolution scale: 100% initially.
  • V-Sync: off in-game if you are using a driver-level frame limiter and adaptive synchronization.
  • Frame rate limit: start at 60 FPS on a 60–75 Hz display, 90 FPS on a 100–120 Hz display, or 117–141 FPS on a 120–144 Hz display.
  • Textures: High with 8 GB of VRAM; Medium if your card has 6 GB or less or if texture-streaming hitches occur.
  • Shadows: Medium.
  • Effects and post-processing: Medium.
  • View distance: Medium or High, then reduce it if CPU frame time spikes.
  • Motion blur, film grain, and chromatic aberration: Off.

A frame cap is important because it prevents the GPU from constantly rendering as fast as possible, leaving little scheduling headroom for asset streaming and CPU-side work. A cap that is slightly below refresh rate is often smoother than an uncapped frame rate that repeatedly jumps between 70 and 120 FPS.

3. Reduce the settings that affect the CPU first

Lowering resolution will not solve a CPU bottleneck. In crowded rooms, the processor must still update AI, collision, animation, sound events, doors, lights, and other game logic regardless of whether the image is rendered at 1080p or 1440p.

Use this CPU-focused order

  1. Lower view distance from High to Medium.
  2. Lower shadows from High or Epic to Medium.
  3. Lower effects from High to Medium.
  4. Reduce volumetric or fog-related quality if the option is available in your build.
  5. Keep textures unchanged unless VRAM usage or streaming is the problem.

View distance can increase the number of visible objects and draw calls, while shadows and volumetric effects add work around lights and geometry. Test one setting at a time in a busy mission rather than judging performance in the menu or an empty hallway.

4. Fix shader-compilation stutter

Unreal Engine games can hitch the first time a particular material, effect, weapon, light, or environment combination is used. A graphics driver update, game patch, changed renderer, or cleared shader cache can make this happen again.

  • Launch the game and remain in the main menu for a few minutes before starting a mission.
  • Play through a location once without repeatedly changing graphics settings.
  • After changing the GPU driver or major game version, expect the first run to be less smooth while caches are rebuilt.
  • Do not repeatedly delete shader caches as a routine “fix”; that removes data the game needs to avoid compiling the same shaders again.
  • Keep the game and graphics driver updated, but avoid changing several driver profiles during troubleshooting.

If stutters become worse after a driver update, use the driver’s shader-cache reset option once, restart the PC, and let the game rebuild its cache. Do not use random cache-cleaning utilities that remove unrelated game files.

5. Reduce texture-streaming pressure

Texture quality mainly consumes VRAM. When the game runs short of available VRAM, it may stream assets through system memory and storage, producing sudden hitching as you turn toward new rooms.

Still Dropping Frames? When an Upgrade Makes Sense

If Ready or Not still stutters or falls below your monitor’s refresh rate after every fix above, the limit is usually the graphics card or system memory rather than a setting. These are common upgrade paths for that situation.

Frequently asked questions

Should I lower resolution if Ready or Not stutters during busy raids?

Not if the problem is CPU-related. Lowering resolution does not reduce the processor work required for AI, collision, animation, sound events, doors, lights, and other game logic. First lower view distance, shadows, and effects from higher settings to Medium, and reduce volumetric or fog-related quality if available. Lower resolution or resolution scale when GPU usage stays near 99%.

Why does Ready or Not stutter when I enter a new room?

Short hitches when entering a new area often point to shader compilation or texture and asset streaming. Let shaders finish compiling, remain in the main menu for a few minutes before starting a mission, and play through a location once without repeatedly changing graphics settings. If texture streaming is involved, lower textures or reduce other texture-streaming pressure.

What frame-rate cap should I use for smoother gameplay?

Start at 60 FPS on a 60–75 Hz display, 90 FPS on a 100–120 Hz display, or 117–141 FPS on a 120–144 Hz display. A cap slightly below refresh rate can improve frame pacing compared with an uncapped frame rate that repeatedly jumps between 70 and 120 FPS. Use one synchronization method.

Could insufficient VRAM cause sudden hitching in Ready or Not?

Yes. When available VRAM is insufficient, the game may stream assets through system memory and storage, causing sudden hitching as you turn toward new rooms. Use High textures with 8 GB of VRAM, or Medium with 6 GB or less. For 4–6 GB cards, Medium textures are a starting point for 1080p; watch for texture pop-in and streaming spikes.

Should I delete shader caches to fix repeated stuttering?

No. Repeatedly deleting shader caches removes data the game needs to avoid compiling the same shaders again. Keep the game and graphics driver updated, but avoid changing several driver profiles during troubleshooting. If stutters become worse after a driver update, use the driver’s shader-cache reset option once, restart the PC, and let the game rebuild its cache.
