FPS drop when I move the mouse with the screen and click at the same time

My problem is that when I move the camera with the mouse and click at the same time it gives lag and a drop in fps only in Zeqa, because in Divinity this does not happen to me. And neither in the normal Flarial, the version v1 did not have these problems on the servers and now that I changed to Flarial v2 this problem occurs to me
