I've got a 5 year old refurb Lenovo that is getting pretty slow at times. My kids play Farm Simulator 19 on it. Does good in the game, but with the game running, the computer is almost impossible to use for anything else. Closing the game requires what feels like several minutes of "thinking" where the thing is useless. Specs are: Intel core i7 3.4 GHz and 8 GB of ram. Have a 500G hard drive with 64 G of space left. I have a Gigabyte Geforce 1050Ti graphics card. Everything is at or above the requirements for the game. What do I need to do to speed this thing up when it's running the game or closing it?
