Hey everyone, just circling back to say the fix worked—huge thanks! Long story short, I was chasing these random 5-10 second framedrop stalls in a DirectStorage-heavy title and it turned out my GPU was thrashing during asset decompression because of how the memory carve-out was configured. Per u/VRAM_Wizard’s suggestion, I went into the BIOS and adjusted the above-AGP / resize BAR aperture allocation (basically bumped the GDDR carve-out and locked it to the full 48GB instead of the default capped region), and I also enabled the re-association / resizable BAR option that was sitting disabled alongside my CSM settings. Rebooted, verified the full VRAM addressable range showed up in the GPU-Z readout, and the stalls are completely gone—I’ve now got a rock-solid 144fps with zero dips over a four-hour session. Moral of the story: I really should’ve checked the BIOS memory mapping before assuming it was a driver or thermal issue. Appreciate the help, fellas!
