Apple does stuff like this so much and gets so little flak for it. I us…

I guess that's true, I forgot about Apple making Rosetta 2 installable in Linux VMs. Also though, since Rosetta 2 was released, it's had an incredibly slow implementation of x87 FPU operations, and anything that relies on x87 floating point math (including lots of games) is currently running about 100x slower than it ought to. Apple is aware of it but it's still not fixed in Ventura. I hadn't heard of FEX before, loo…
Huh, I thought everyone used SSE floats these days. I suppose there may be old games compiled with x87 floats, but I'd expect those to be made for CPUs so old that even slow x87 emulation wouldn't be a big issue. What software do people have x87-related issues with?
The author of REAPER has also written about it some: https://user.cockos.com/~deadbeef/index.php?article=842
There's been lots of discussion about the issue in the Codeweavers forums, and Codeweavers points the blame squarely at Apple, who have been, predictably, very quiet about it.
Couldn't you just pre-multiply the projection matrix to remap the Z range from [-1,1] to [0,1]?
This is the same as modifying a projection matrix -- you're doing the same post-multiply to the same column. But note that there's no guarantee there's ever a projection matrix. Clip space coordinates could be generated directly in the vertex shader.
I don't know why there's so much love for OpenGL in the communities still. Maybe it's the "open" part in the name, which was always confusing people, thinking it's an open source standard or something like that. The API is very antiquated, doesn't match modern GPU architectures at all and requires many workarounds in the driver to get the expected functionality, often coming at a performance cost. Vulkan is nice, but…
You acknowledge that Vulkan is too low level for people who aren't investing billions into an AAA graphics engine. And you surely know that OpenGL and Vulkan are the only two cross-platform graphics APIs. Are you sure you can't infer why people like OpenGL from those two points? Especially in Linux-heavy communities where DX and Metal aren't even options? I assure you, none of the "love" for OpenGL comes from the ele…
Can you run a PCIE enclosure over thunderbolt on asahi Linux yet? Could this enable GPUs that already work on aarch64 Linux?

I really wish Apple would do another "Snow Leopard" - go an entire year WITHOUT any new features and just fix bugs and documentation. This twitter thread is a perfect example of why it's needed https://twitter.com/nikitonsky/status/1557357661171204098
Snow Leopard had few user-facing features, but it did have new APIs, such as Grand Central Dispatch and OpenCL, and also an optional 64-bit kernel. https://en.wikipedia.org/wiki/Mac_OS_X_Snow_Leopard

Despite the progress here, for me it raises a question: Most of the old games she mentions are x86 32bit games. What's the story for how these programs are actually going to run in Asahi? Box86 [1] doesn't sound like it's projected to run on M1. Rosetta 2 on macOS allows 32-bit code to be run by a 64-bit process, which is the workaround CrossOver et. al. use (from what I understand), but that obviously won't be avail…
