The game started to lag very much (Rust)

I play on a laptop, harki - gtx1050ti, intel core i5 9th generation, 8 GB of RAM, on 10 Windows. About a month ago, I started to lag strongly (not from graphics), before that the FPS was 60-90, but after a while, when I started on the server, very good. lag and freeze a lot, if you do nothing, then on the server 80 fps, but with any movement the fps sags to 20 -30, even when I open the map, but after reinstalling Windows, the lags are removed for a week - 2, and then all over again, at f8 , at this time, almost completely red stripe, tried many methods, but nothing helps, who can help, I will be very good. grateful
