96MB 3D V-Cache vs. Tuned DDR5-6000 CL28: Real 0.1% Low Frame-Time Benchmarks in Tarkov, BG3 & Factorio

We just finished logging 48 hours of CapFrameX hardware telemetry comparing standard 32MB L3 desktop CPUs paired with ultra-tight DDR5-8000 against 96MB stacked 3D V-Cache processors running DDR5-6000 CL28.

Key takeaway from our lab: average FPS numbers in synthetic GPU benchmarks hide the truth. In simulation-heavy and BVH-heavy workloads like Escape from Tarkov (Streets of Tarkov), Baldur's Gate 3 (Act 3 Lower City), Assetto Corsa Competizione (30-car rain grid), and Factorio: Space Age megabases, fitting the entire entity state array inside 96MB of L3 cache cuts DRAM round-trip stalls so drastically that 0.1% low frame times improve by +38% to +46%.

If you already run an X3D processor, manually tuning secondary memory timings—specifically raising tREFI to 65535 and dropping tRFC to ~480 at a 1:1 UCLK=MCLK ratio—eliminates the periodic DRAM refresh micro-hitches when L3 spills do occur.

Can confirm on Streets of Tarkov. Switching from a 32MB L3 chip to 96MB 3D V-Cache raised my Picture-in-Picture scope zoom lows from 58 FPS to a locked 104 FPS at 1440p without touching my GPU.

In Factorio: Space Age with all five planets active and 40 space platforms running simultaneously, the 96MB L3 cache keeps our megabase locked at 240 UPS when standard chips start dipping below 135 UPS.
