This Trick Can Double Your VGA Performance In DOS! Bits und Bolts 2025-08-28 | Have 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!UniVBE can be found on Vogons: vogonsdrivers.com/getfile.php?fileid=346S3 Trio64V2 VESA VBE 2.0 BIOS: https://gona.mactar.hu/DOS_TESTS/ (I will cover this in a future video).HWiNFO for DOS: hwinfo.com/download▬▬▬▬ *Affiliate Links* ▬▬▬▬▬▬▬▬▬▬▬▬▬Visit my website to find affiliate links to most of the tools and products I use🔸bitsundbolts.com/affiliateThank you for your support!▬▬▬▬ *Support Bits und Bolts* ▬▬▬▬▬▬▬▬▬▬Patreon: 🔸patreon.com/BitsUndBoltsBitcoin: bc1q2dvf9flf78lam33qjj9w9xgvfxdgre7g9x3rmwTwitter/X: 🔸twitter.com/BitsUndBoltsFacebook: 🔸facebook.com/bitsundboltsWebsite: 🔸bitsundbolts.com▬▬▬▬ *Timestamps* ▬▬▬▬▬▬▬▬▬▬▬▬▬▬00:00 VESA BIOS Extensions01:54 Identify your VBE version02:37 PC Player Benchmark Secrets04:24 VBE 1.2 vs VBE 2.005:42 Banked Memory Explained08:02 More than 640K Conventional Memory10:52 Duke 3D Screen Setup14:41 UniVBE / Enable VBE 2.019:09 Benefits of the Linear Frame Buffer20:32 Visualize the Linear Frame Buffer21:46 Linear Frame Buffer Tests23:42 S3 Trio64V2/DX BIOS VBE 2.0 compliant24:06 Supporters

Does it make sense to swap those CPUs? Bits und Bolts 2024-12-19 | I have this board, an M396F V2.6, which I am sure has the least components in my collection.
