CIT Resewn has two issues in large modpacks. First, it re-evaluates custom item textures every frame even when nothing has changed — this causes unnecessary CPU usage when browsing large inventories or EMI item grids. Second, it leaks over 1 GB of RAM per session by allocating objects into every ItemStack that are never freed.

What does HTP CITOptimizer do?
Caches CIT evaluation results so repeat lookups are skipped, and fixes a massive memory leak. Significantly reduced GC pressure from eliminated per-frame allocations. Lower CPU usage when browsing large inventories or EMI item grids.
Your client will no longer freeze, crash, or lag after hours of gameplay requiring a restart due to CITResewn.
We were experiencing memory climbing steadily until it hits the heap limit causing stutters multiple times per day most noticable when relogging on servers.
