If the error started after a recent update, use Device Manager to roll back to the previous stable driver version. 4. Apply the 4GB Patch (For Older 32-bit Games)

PS2 emulators (PCSX2) see a similar pattern in the GS (Graphics Synthesizer) registers. The "frame buffer8" corresponds to the PS2's PSM_T8 (8-bit paletted texture mode). The "fixed hot" register is the FRAME register in the GS. A recent commit in PCSX2 (v1.7.5+) specifically notes: "Optimized 8-bit framebuffer register readback, reducing hot path overhead in Bink videos by 40%".
