Why GTA IV (PC) stutters

GTA IV’s PC port still streams awkwardly; FusionFix/DXVK stacks plus high draw distance hitch when RAM is low during bridge traversals.

What RAM kit to buy

For GTA IV (PC), shop matched dual-channel UDIMM kits at 16GB (2x8GB dual-channel) before spending on RGB or extreme CL. Populate the primary dual-channel slots (usually A2/B2) and enable XMP/EXPO so DDR5-6000 CL30 actually trains for GTA IV (PC). Reserve 32GB builds for heavy Open World / Action mod stacks or RAGE asset packs on GTA IV (PC). Live kits below prefer in-stock DDR4/DDR5 modules that clear the 16GB floor for gta-iv-pc.

Engine, genre & mod notes

GTA IV (PC) streams open-world RAGE assets aggressively — downtown/NPC density is where 16GB kits page hardest. Open-world/RPG streaming is the classic false GPU stutter — watch commit charge when entering cities. Mod / extra load: Various fixes + texture packs — 16GB dual-channel is the modern baseline.
