Could you help, pls?

Update your graphics card drivers

And if that doesn't work - please provide more information such as the OS and the branch you're playing on.

Nvidia driver - 471.96
OS - Windows 10 Home Edition
FAF Client - 1.5.0
Trying to install Nvidia fix mode - didn't help

Found the problem and its solution, but it works only in original Steam game - you should open the console and paste this: d3d_windowscursor
But in FAF console didn't work

That command does work in the FAF console, usually opened with the ` key. You can also use the nvidia fix mod

Yes - make sure it is enabled (!), installing on its own is not sufficient.

Nvidia fix mod doesn't work, but command in the game works. Have only problems in the lobby - the key ` don't open the console. I think problem solved, ty

The mod does the same thing as the command in game—as Jip mentioned, you need to enable it.
