Nvidia has just demoed its Neural Texture Compression technique again at a GTC talk, where it showed VRAM usage dropping from 6.5 GB to just 970 MB in a scene. NTC uses a neural network to decompress textures instead of standard block-based compression, reducing texture size and VRAM usage while also improving final image quality.

Two new Rowhammer attacks for GPUs have been discovered that can cause bit flips in VRAM to gain arbitrary read/write access over it. These attacks target page files and the page directory that are otherwise protected from electrical disturbance by the driver. By "massaging" these data structures into vulnerable regions where a bit flip can occur, the attacker can access even the CPU memory.

A console modder has created a custom PCB featuring components from the original PS1 and PS One motherboards. The PCB also integrated an XStation to add native microSD card support and an HDMI modkit to enable 1080p HDMI out to modern displays. The entire motherboard consumes less than 2 watts and runs at just 3V.

The r/programming subreddit has banned all discussions related to LLMs to foster a more thoughtful community that focuses on high-quality discourse around AI. Posts on AI are still allowed, but only if they're technical and contribute meaningfully instead of promoting things like vibe coding. LLM-generated content is also strictly no-go.

The Nvidia App can now automatically recompile shaders for you in the background after every GPU driver update. This should save gamers several minutes across different titles, especially blockbuster ones, where shader compilation can often delay your session. You still need to compile shaders for the first time after a new install, however.

An enthusiast has managed to get Intel's non-consumer Bartlett Lake CPU running on a regular Z790 motherboard, thanks to AI. Claude modded the original BIOS of the board to detect a Core 9 273QPE and boot with it, but the setup hasn't gotten past the POST screen yet, and the modder is currently facing various error codes.
