Give us the gritty details of patches

Today's patch has performance improvements. A patch a good while ago had performance improevments. That last one was nuts, the load times went down like crazy and the game has never run smoother- 3x and 4x speed finally worked properly after years and years and both ran smoother than at launch with no packs installed. it was incredible.

Today's patch I haven't played with yet- but what actually was improved? Would love to see deep-enough dives into what changes were made and where to expect visible, tangible improvements. For example it mentions graphics- what would improve about the graphics, performance-wise? What does that mean? I'm assuming LOD improvements (As Sims 4's LOD distances are strangely restrictive, with trees and rocks popping into different detail way too early IMO). But we dunno, cuz you don't tell us!

Let us know what actually may have changed! The more technical players wanna know what to look for!
