Yeah, don’t do that anymore then. Firstly the video doesn’t really find overall 2x speedup, but mainly Cycles X came out since then, where most of the codebase has been rewritten from scratch, and after that numerous significant optimizations happened as well. That video is pretty much irrelevant now.
Afaik Blender since 3.0 does not support OpenCL anymore and AMD rendering uses HIP instead. I have not found any information about dramatic performance differences, though CPU rendering does seem to be somewhat faster on Linux - but more like 10% faster and the amount of computation practically done on the CPU is not that big.
Also this represents the biggest headache in Linux, lots of gamers insist they can only use Nvidia cards. Nvidia treats linux as an afterthought as best or deliberately sabotages things at worse.
Personally I use NVidia because of CUDA, gaming is an afterthought. I wish CUDA just fucked off and we got some universal compute API instead, because that’s what would reduce the NVidia stranglehold on the market, perhaps OneAPI is going to catch on at some point, but at this moment those options are not practical.
the best example is Blender which works almost twice as fast on Linux
People say this, but what exactly do you mean? I mostly model on windows because it’s my primary system (I use applications that simply don’t work well enough with wine), but mostly finish and render stuff on linux because of windows’ retarded automatic updates etc. that can just cancel rendering without asking. And the only difference I’ve seen is how fast Blender starts - I’d say that’s more than 2x as fast on linux, it’s a huge difference. But rendering is the same (NVidia GTX GPU) and other work inside blender also seems to be about the same.
Imo it’s the latter. It didn’t start that way, but in the last decade they gradually shifted to being simply inflammatory on purpose because that brings clicks, and on top of that they regularly did dumb shit like complain about sexualization and male gaze one week (often, though not always, legitimately, but mostly it was literally just complaining without any further insight, which I personally don’t care bout) and next week publish an article with photos of top male bulges in some sport that, apart from the gender being swapped, was literally worse than what they complained about with regards to sexualizing women.
Personally I say good riddance, but I’m biased by a deep dislike for people who use identity politics to create divisive clickbait.
