Hi, The location of the controller is rendered correctly but when i am doing a simple line trace from the controller, the line trace seems to be “bouncy” (when you move the controller the line trace did not follow the controller correctly; it seems to move arround the controller). I can check “disable low latency update” and it is much better but i don’t think it is the right way to do it. I tried to make a clean project with nothing else except the basic configuration of a VR project (using ue **4.12.3** ) (same as here : [https://docs.unrealengine.com/latest/INT/Platforms/SteamVR/QuickStart/2/index.html](https://docs.unrealengine.com/latest/INT/Platforms/SteamVR/QuickStart/2/index.html)). Then in my VR\_Pawn i add this : And here is the pawn components : Perhaps i am missing something ? Any help would be really appreciated. Best regards (and sorry for my english, it is not my native language) greg ---

Hello greggus, I believe that “disable low latency update” would be the correct workflow for the issue that you are describing. Are you saying that there is still a high amount of latency? ---

Hello, In a blank project i didn’t notice latency if i tick “Disable Low Latency Update” but i thought we must not disable it since it causes the controller to lag behind our movements. I found a video that describes the problem : [- YouTube](https://www.youtube.com/watch?v=PL8ptJ3R7Wc) @ 10s we can see the blue laser movement that move arround the controller If i move the controller very fast it is easier to see. I make a simple project if needed : [https://drive.google.com/folderview?id=0BzG3xmhxj\_zQQ3haOFlIb2pIcW8&usp=sharing](https://drive.google.com/folderview?id=0BzG3xmhxj_zQQ3haOFlIb2pIcW8&usp=sharing) ---

I just tried the VR editor and the line coming from the controller do not have this problem. ---

I was able to reproduce this issue on our end using the project provided. I have written up a report ( UE-32642) and I have submitted it to the developers for further consideration. I will provide updates with any pertinent information as it becomes available. Thank you for your time and information. Make it a great day ---

How is the progress now, we also encounter such a problem, the tail of the knife has a sense of lag. ---

How is it going ? I double check and no latence over Oculus. How is this possible that it still doesn’t work over since 2016 ? I experiment lag with body animation. Thanks for any help
