I've bought a new mouse + a new PC but my mouse hangs and jerks in because playing Fortnite / Black Ops 2 so eig everything.
I have the Speedlink mouse OMNIVI
This mouse may need a special driver that you did not install.
On my old PC, I had no driver on it and everything went.
It may be that you may go up a little with the mouse and then the laser fails. Maybe your movements are too fast for the mouse.
I can't explain anything else!
Assuming that the sensor in there's good:
Polling rate set low (should be set to 1000hz)
Driver needs or conflicts with other driver.
Broken.
Ergo check in turn.
Where can I see how much hz it has?
It hangs and jerks only in games.
I do not have the mouse, read the instructions.
