Renoise 2.8: Does signal follower cause latency?

I’m suddenly getting mad latency on my latest tracks… Is it because of signal followers and hydras?

The Signal Follower only introduces latency when you have Lookahead set higher than 0 ms.

To check for latency introduced by plugins, go to the main menu: Options > Plugin Delay Compensation Info

(In 3.0 you can find it in the Song menu)
