Why performance can dip
Screen capture reads frames from the display, and playback/recording uses CPU and memory. On modest hardware, high capture settings (longer buffers, higher frame rates) can compete with a game for resources.
Reduce the capture load
- Lower the capture frame rate in settings — recording fewer frames per second uses less CPU and memory. Set it to what you actually need.
- Shorten the replay duration — the free version's 30-second buffer can be lowered, and a shorter buffer means less memory. Pro users can still drop to 30 seconds when performance matters more than length.
- Close unnecessary background apps during heavy gaming or recording sessions.
- Run Replayable as administrator so its capture path isn't throttled behind other processes — but note this grants it elevated priority in the game's own capture pipeline too.
Hardware factors
- The encoding load happens when you save, not continuously, so a slow drive or CPU mainly affects how long saving takes.
- Older or lower-power CPUs will see more impact from always-on capture; lowering the frame rate has the largest effect.
Check it's Replayable
If performance is poor even with the lowest settings and Replayable closed, the slowdown is coming from something else — check other background apps and updates first.
