Jeff Geerling ☛ Big GPUs don't need big PCs
The Raspberry Pi only has 1 lane of PCIe Gen 3 bandwidth available for a connection to an eGPU. That's not much. Especially considering a modern desktop has at least one slot with 16 lanes of PCIe Gen 5 bandwidth. That's 8 GT/s versus 512 GT/s. Not a fair fight.
But I wondered if bandwidth isn't everything, all the time.
I wanted to put the question of utility to rest, by testing four things on a variety of GPUs, comparing performance on a Raspberry Pi 5 to a modern desktop PC: [...]

Tech Times ☛ SteamOS Update Unlocks Better Performance and FPS Boosts for Linux Gaming Handheld Players
The latest SteamOS update signals another leap forward for Valve's handheld gaming ecosystem. Designed primarily for the Steam Deck and other Linux gaming handheld devices, this update prioritizes performance improvements that translate directly into smoother gameplay, higher frame rates, and better system stability.
The move reflects Valve's continued push to optimize Linux-based systems for mainstream gaming while bridging the gap between portability and power.
[...]
For instance, Cyberpunk 2077 now runs at more stable frame rates, averaging around 50 fps on medium settings, compared to fluctuations in previous versions. Elden Ring registers consistent improvements in frame pacing, contributing to a noticeably smoother experience during combat sequences.
Even older titles see benefits. Games using Proton layers now launch faster thanks to optimized shader caching and reduced CPU idle time. These optimizations not only enhance gameplay but also improve power efficiency, allowing for longer gaming sessions without excessive heat buildup or rapid battery drain.

ArchLinux ☛ NVIDIA 590 driver drops Pascal and lower support; main packages switch to Open Kernel Modules
With the update to driver version 590, the NVIDIA driver no longer supports Pascal (GTX 10xx) GPUs or older. We will replace the nvidia package with nvidia-open, nvidia-dkms with nvidia-open-dkms, and nvidia-lts with nvidia-lts-open.

Tom's Hardware ☛ You can force FSR 4 Redstone to work on RDNA 3 GPUs with new workaround for GNU/Linux systems — solution requires Proton compatibility to work properly
AMD's answer to Nvidia's DLSS 4 seemingly works on older hardware but is currently not officially supported.

Modder Runs AMD FSR 4 Redstone Frame Generation on RDNA 3 but Only on Linux
AMD recently released FSR 4 Redstone Frame Generation, which, in our testing, provided a decent uptick in perceived smoothness and image quality. However, one of the biggest disappointments for Team Red gamers was that Redstone is officially exclusive to AMD's RDNA 4 GPUs, limiting it to GPUs in the RX 9000-series cards. One enterprising Reddit user, however, has seemingly managed to get FSR 4 Redstone Frame Generation running on an AMD Radeon RDNA 3 GPUs—and no older than RDNA 3—using OptiScaler and the same FP8 workaround as was previously demonstrated to work with FSR 4 Super Resolution.
