There is the phenomenon on Linux where when double-buffered rendering and missing vblanks can lead to the GPU running at a lower frequency when instead the opposite should happen so it will try to not miss vblanks in the first place. In the past there's been talks of "boost" support in the GPU drivers or also workarounds from user-space like dynamic triple buffering, but sent out this week is a new proposal around DMA-Fence deadline awareness as another means of addressing this problem...

When sticking to Wine recommendations of maintaining separate prefixes per-application, a lot of system files get duplicated for each game/application and in turn leading to significant bloat. With the current state of Wine it can mean hundreds of megabytes per prefix in duplicated files. But proposed reflink patches for Wine are aiming to cut down on this severe bloat...

This past week were the initial Linux benchmarks of the Ryzen 9 5900HX with the ASUS ROG Strix G15 laptop. Ubuntu was used as the default test platform as usual given its popularity and arguably the most relevant Linux distribution to use given that it's the most common Linux distribution at the moment for preloads on laptops by multiple vendors. In any case, as usual many users were quick to say "but Arch Linux!" as if it was going to make a dramatic difference in my findings. Well, here are some Ubuntu 21.04 versus Arch Linux benchmarks on that AMD Advantage laptop.
