Pre-Release Update

Quick Take

We now have a new pre-release build (1.41.1.3-rc1) available in the CS2 beta depot, but it's not compatible with public matchmaking. Engine updates include bullet penetration rework and CPU usage reductions for particle and sound processing. Defusing C4 now lowers your viewmodel, prevents scoping, and delays firing by 150ms after you stop defusing. UI improvements make highlight clips viewable from the Spectator Loadout and the selected player more visible in the Team Counter.
