Hi everyone, I found that Unreal Engine seems to have a big input lag, especially since 4.25, the touch lag is very serious. After testing, it was found to be about 60-80ms
My test method is as follows:
Create an Actor Sequence and move a plane continuously. Write a blueprint to stop the sequence immediately when touch input (Touch1 event “PRESSED”) is received
I used Xiaomi Mi Pad 5 to record the screen. When the Android system received touch, the timing starts. In the case of 90FPS recording, Unreal Engine took 6 frames to stop the sequence
This is not a problem with the screen recording and the device. When I tried it on Unity, it only took 1 frame (the next frame when the system receives input) to respond immediately
I want to know what’s going on. This has been bothering me for a long time. I searched a lot but got nothing. If anyone has suggestions, I would be very grateful
