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.

My experience so far has been:

• “default” reddit, like /r/popular etc. has been worse, because reddit started using some form of “the algorithm” which pretty aggressively pushes controversial subreddits with high engagement, and those tend to be dumb and toxic. Amitheasshole, twohottakes etc. are the most obvious ones.

• customized, highly selective reddit with as much crap from the frontpage as possible unsubscribed from is not significantly worse than a year ago, but then again, it was already pretty bad a year ago. Since the API changes I’ve had 3 people block me to get the last word in an argument, for simply disagreeing with them, without me being an asshole. This is quite annoying in a small subreddit where such a person posts regularly, but it may have just been bad luck.

• Lemmy… Well, 3 things that I probably dislike about reddit the most, not because they’re the worst things that happen there, but because they’re so damn prevalent, are overmoderation (heavy handed deletions of posts and comment trees, unnecessarily locking threads that are even mildly controversial, things like banning people for ever posting in a controversial community etc.), strong american partisanship where if people realize you don’t agree with them on everything with regards to society/politics/culture wars, they immediately assume you’re from the opposite american camp and that you must have bad intentions, and finally simply people not being very smart on average.

Well, all three of those problems seem to be just as prevalent on large Lemmy instances, the first two even more in some places. And whereas on reddit many people understood that you’re probably not realistically going to be able to create an alternative subreddit to some huge default with hundreds of thousands of users, so the “go make your own subreddit” copout is not very practical, here “go make your own instance” seems to be one of the default reactions to any criticisms.

That said, Tildes seems to be doing okay. It’s even smaller and it doesn’t really try to be a reddit alternative, but it’s considerably smarter and more sane on average than both Reddit and Lemmy.

I think that's willfully distorting the situation. Punching down should refer to jokes that seem to be or obviously are made with malicious intent, it's not about certain groups being protected from humor altogether, that's infantilizing. From what OP said and posted somewhere in this thread I don't think their jokes were in any way malicious.

In my experience from lurking around Lemmy, it seems that the big instances are largely populated by stereotypically "reddit-left" people, which includes finding a lot of things offensive (whether they're actually offended or not) and being relatively hostile to people who don't seem to share their worldview, seemingly considering it the default that everyone should know and accept. You can see it in this thread as well.

Not being an American and being culturally outside of american partisanship, this has been quite the disappointment for me, but what can you do.
