Fixing Kioxia EXCERIA G4 cache overflow in Grand Theft Auto VI?
Tearing through the streets, my frame rate would suddenly plummet from 80 FPS down to 30 FPS, which is honestly anxiety-inducing. The problem is that once the Kioxia EXCERIA PLUS G4's dynamic SLC cache fills up, the write speed craters from 5000MB/s to under 1200MB/s, creating a massive I/O bottleneck during background asset swaps. I tried bumping the page file to 64GB, but that actually made things worse by increasing disk contention, which was incredibly frustrating. I eventually went into Device Manager, disabled power management for the NVMe controller, and enabled Fast Boot in the BIOS. In CrystalDiskMark, 4K random writes jumped from 40-55MB/s to 68-82MB/s, and the city loading became way more fluid. I tried lowering texture quality early on, but since it was a low-level scheduling issue, the drops persisted until I optimized the write strategy. Drive temps are now sitting between 52-60℃, and the input lag is finally gone.
