The rotation is not smooth when the mouse is showing/显示鼠标后转动时画面卡顿

[Ravyn_Clown (ParanoidAndroid)]

bShowMouseCursor勾选显示鼠标光标以后，左右旋转视角就变得卡顿，在较大的运动中还会有明显的抖动。移动的视角并不受影响，还是比较丝滑的。有什么办法可以优化一下吗？添加运动模糊之类的？
复现：我只是在第一人称模板里的“事件开始运行”的最后加了一个set bShowMouseCursor

When bShowMouseCursor checks the display mouse cursor, the left and right rotation angle becomes stuttering, and there will be noticeable jitter in larger movements. The moving perspective is not affected. Is there any way to optimize this? Add motion blur or something?
Reproduce: I just added a set bShowMouseCursor at the end of the “begin play” in the first-person template.

Found a solution. Use Set Input Mode Game and UI and select Hide Cursor During Capture, it allows the mouse controller to hide the cursor when it is captured, thus reducing lag caused by rendering.
