Reduced ProcGen Garbage Added Mummur Hash to reduce collisions Improved LinearProbe by caching the accessed key, instead of reading it twice Added IntHashSet Switched Maps over to IntHashSet since the additional value was unnecessary Pass in worldPos when getting tileOverride since it's already calculated Fixed Iterator generating 500MB of garbage during scene load Cache is read on multiple threads, we cannot guarantee the last alhsl value will be fully written in time Cache the last searched key result Added Bounds around multiple AABBs to allow for early out Fixed Double Linear Probe Implemented Robin Hood Hashing Dynamic Model Upload Optimizations Calculate Int Bits of Vertex position once instead of multiple times per face Added Normalized value fast path for fp32 -> fp16 conversion Calculate invLength instead of diving each axis undoVanillaShading Tweaks colorAdjust only needs to be calculated within the inner part of the if, otherwise the value isn't used We can use nDotL instead of the length Early out if value should be ignored Early out on nDotL Made FindIndex static since its consistent across all collections Refactored LastRead into a 32 Byte ReadCache findIndex optimizations Switch GLState IntSet to use IntHashSet & not the generic HashSet Tweaks Pre-Compute SINE/COSINE Float Arrays matching Perspective.SINF/COSF Tweaks

A FIFO cache around theModelOverride::AhslPredicate results for given Ahsl keys, cache is made up of Longs, 32 bits for the ahsl, 1 bit for the result, are 31 bits for the age used during eviction.
Cache by default starts at 16 & has an upper limit of 512 values before it'll begin evicting values by the oldest first.
