Did you figure out the reasons for the high ping? I suppose it could be related to a system failure at your internet provider. I hope everything has stabilized now. I also wanted the system to show ping and FPS in CS2, so I decided to ask my brother, who knows about these things, for advice. He sent me an article by VRedux, which turned out to be not only informative but also easy to understand. I decided to save time and enter the command through the console so that everything would work right away. Now I have these indicators in the upper right corner, and everything is perfectly configured for me.
