CS2 Patch Notes - 18th May 2026

Grenade jump throws get a consistency pass in today's CS2 update, and the jump throw preview camera has been made more accurate too. For a game where a pixel of can decide a round, that's a fix competitive players will actually feel.

The other change is weapon_accuracy_stack_boost_limit, a new convar defaulting to 2 that applies ladder inaccuracy to players being boosted by a stack of two or more teammates. Boosting has always been a niche but legitimate tactic, and this adds a real accuracy cost when you're riding a human pyramid. Valve clearly wants to keep it viable without letting it become a no-downside exploit. The AWP draw-to-idle animation also gets a small tweak, which won't shift the meta but should feel cleaner in hand.

On the spectator side, three separate bugs are fixed: a post-processing glitch when switching targets across maps with different volumes, stuck x-ray silhouettes, and a broken damage overlay. Map scripting gets a sizeable API expansion too, which modders will want to dig into. Here's everything that changed.
