📋 About This Mod
GC Boost is an mod who boost the Garbage collector for the Witcher 3 Next-Gen, you can use it if you use big modlists or graphics mod
The mod reduces pop-in, improves the loading of large graphics mods (for example: HD REWORKED PROJECT NEXT GEN), allows the engine to store more and better meshes (and render them a bit more detailed), and also slightly boosts the graphics, but the difference is only really noticeable if you use several graphics mods.
GC Boost change the GC.ini and boost some variable
The mod can make some graphics visuals a little better.
GC.ini (Modified) ;
; Lower limit for amount of free memory in the default pool that will automatically trigger the GC
; DefaultPoolMemoryTrigger = 5000
; Disable triggering by object pool as this is not reliable now
DefaultPoolMemoryTrigger = 5000
; Limit for the mesh memory pool trigger
MeshPoolMemoryTrigger = 512
