Considering I’m somewhat of a PC Luddite, and avoid updating my BIOS, Windows, or drivers unless it’s critical, flashing my GPU BIOS was certainly out of the ordinary. I’ve known about custom vBIOS for a while, and how it can increase performance by tweaking the stock power limits or clock speeds, but I decided to actually do it only recently. My existing graphics card is starting to show its age, and I wanted some extra performance.
