This Trick Can Double Your VGA Performance In DOS!
2,318Have you ever heard of VESA or VBE? VBE 2.0 revolutionized DOS graphics programming by introducing a linear framebuffer that eliminated the cumbersome bank switching of earlier versions, allowing for direct and much faster access to video memory which could genuinely double performance in VGA-intensive applications. Beyond speed, it added protected mode support and enhanced compatibility with non-VGA controllers, making it easier for developers to create high-resolution, color-rich games and software without hardware-specific hacks. Dive into the video to uncover the simple trick that unlocks this power and transforms your retro PC setup!
