Absolutely useless. The game is unplayable. I play against full cheaters two out of three games when I get above 17k elo. Valve make hundreds of millions with clearly no regard for the player base. I have a 16yo steam account, thousands of hours in games and I play against people with new steam accounts and 50 hrs. They should be making a cutting-edge anti-cheat but as long as people keep buying crates they don't seem to care.
CS2 needed two things, an anti-cheat that works at least a bit, and 128 tick servers. Instead we get a reskin, worse net code, and a change to the smoke grenade.
