Patch Notes: Oblivion gate sound and stutter fixes

Audio

The game no longer distorts when many loud sounds play at once. A limiter now sits on the final output, so the Legion-Lord's heavy blows, his roars and the gate music can't push the mix past full volume. Everyday sound is unchanged.
Hellfire, Meteor, Brand and Torment play at most two copies of their sound, instead of one per targeted player. In a group, a third-phase Hellfire played ten copies at once.
Inside the gate, other players' sounds play 4 dB quieter, as they already do in the Elite Gates Spire, so the boss's warnings stand out.

The gate fight's spark, meteor, crystal and portal effects are prepared as you arrive in the court, instead of the first time each appears mid-fight.
The monsters a gate can field are loaded as you arrive, instead of when the first wave rises or the boss splits in two.
Blood splashes no longer redo their image work on every hit.
With Enhanced Lighting shadows on, the brief flashes of the boss's landings, his fall and the Wrath no longer cast shadows, so they no longer force shadow redraws.
