Quick Answers
Frequently Asked Questions
Quick technical answers on game overlays, clipping performance, and hardware thermals.
Does running an in-game overlay impact my game's FPS?
SysCubes is engineered to have near-zero overhead (<1% CPU). Hardware telemetry is gathered via lightweight native OS APIs and GPU hooks, ensuring smooth framerates even in competitive esports titles.
Why are my CPU temperatures missing from the performance widget?
Modern Windows security requires elevated kernel-level driver permissions to read internal CPU motherboard sensors. Follow our hardware monitoring guide to enable the PawnIO driver cleanly.
How does retroactive clipping work without filling up my drive?
SysCubes keeps a rolling 15-to-40 second video buffer in system RAM. Only when you press your clip hotkey is that buffer encoded and saved as a permanent MP4 file to your disk.
