Does Ollo affect FPS?

• Typically under 1 ms per frame.
• CPU-only and optimized for 120+ FPS projects.

My webcam isn't detected

• Ensure no other app is using the camera
• Try index 1 if you have multiple webcams
• On Linux/macOS ensure permissions are granted

Blink events feel delayed

• Disable VSync (some engines buffer frames)
• Ensure you poll every frame
• On laptops, set high-performance mode

Signing in and the evaluation watermark

• The editor shows the watermark until the machine is signed in: press Sign in in Ollo's panel
• New machine, and all three seats taken? Sign one out from your dashboard, or when you approve
• An exported game shows the watermark when it was exported during the trial or after your plan ended: export again on a paid plan
