How do you like that, AMD? OptiScaler taught FSR 4 to work with Vulkan, while AMD itself still can't.

VR Headset with a CRT Screen? DIY Enthusiasts Amaze

While tech giants compete over whose OLED panels are thinner and brighter, a YouTuber from The Science Elf channel decided to go against the grain. He built a homemade VR headset, using two tiny monochrome CRT monitors instead of modern displays. These are exactly the same kind used in the viewfinders of old 90s camcorders.

The result looks like a prop from some retro-futuristic film, but the most astonishing thing is that this device can actually be used for gaming. The main question is — why? Besides the obvious "because I can," the creator wanted to test the advantages of old technology. Cathode-ray tubes (CRTs) have virtually no display lag, and their black color is truly black, which remains a problem for many budget VR headsets to this day.

Thanks to Fresnel lenses and a specially 3D-printed housing, the image from the two small tubes is combined into a single picture, creating a full-fledged immersive effect.

Of course, there were challenges. The headset turned out to be quite heavy and bulky, and high voltage circulates inside it, necessary for the CRTs to operate (which adds a touch of thrill to the gaming process). Furthermore, the image remains black and white. However, the blogger managed to connect this technological marvel to a modern PC and even launch classic games.
