Custom VR Movement is Laggy

Help and Feedback Scripting Support

I’m trying to write my own VR movement and such for my own game, but I’m having an issue where when moving the joystick back and forth, the player model kinda sticks and moves very slowly forwards and backwards. However, moving left and right works perfectly.

I couldn’t find much online, and I was hesitant about asking ChatGPT but even it was useless (maybe for the best, too). There’s a good chance that the player model itself is the problem as well, but given my limited knowledge on scripting and the fact I haven’t done it in so long, a bug seems very well likely.
