A customer asked for full-screen exclusive compatibility, therefor that has been added, and we needed a client update for that.
Our overlay now also uses DX11 instead of DX12, its less costly when drawing 2D and has broader support
You can also adjust overlay framerate in settings, for those with modern PC's just set to monitor refresh rate, I have no issue myself running at monitor refresh rate with laptop Nvidia 4060 gpu, with no fps cost. so hopefully that accounts for most. Old GPU's like 960 or 1050, might need lower fps.
