I have came across an issue where I use my sparrow it become slow when using it. I'm not the only one having this issue as it's been causing the problem on my wife account too.
We are using sparrows that are set at 160 but when we are using them & we use the boost there is no increase to speed or anything. We have noticed that all other sparrows from other guardians ain't lagging or have any speed restrictions. Could this issue be resolved somehow.
Are you using a controller with trigger stops or an issue with the trigger? Sparrows require a full trigger pull to boost properly, so if anything prevents the trigger from being pulled down fully, the Sparrow isn't going to go much faster, if at all.
