MCBYT successfully set out to reclaim the Minecraft FPS world record, utilizing the RTX 4090 and 13600k. They employed Lunar Client 1.8.9 with performance mods to enhance FPS, ultimately achieving a record-breaking 14,000 FPS in Minecraft. Their efforts also included optimizing the operating system, resulting in a 150 FPS improvement. This journey showcases their determined pursuit to surpass the existing FPS record and regain their throne in the Minecraft community.

The video demonstrates a challenge to achieve 10,000 FPS in Minecraft on a budget gaming PC, achieved through optimization and mods. Various settings, mods, and versions of Minecraft were tried, but the 10,000 FPS goal wasn't reached. The Home PC Optimizer was used to enhance performance, and accidentally exiting fullscreen mode boosted FPS. However, downloading a custom OS led to FPS issues which only led to achieving 8000 FPS.

ItzRealGlitch works with a bunch of Minecraft optimization mods and performance-biased in-game settings that helped him achieve high FPS. They used mods like Sodium, Lithium, Sodium Extra, FerriteCore, Starlight, Dynamic FPS and more. Going to areas such as the Void where nothing has to be rendered, they achieved the 6000 FPS mark.

Yusei's attempt highlights the strategy of maximizing FPS by switching to the newest version and using a newer world. The video addresses challenges, such as OptiFine not working in certain versions, while also noting the addition of new features in later versions. Yusei manages to hit 5000+ FPS in the 1.15 Version.
