It’s all usenet, yeah. I forgot you can use the above programs with torrents too :p

I use NinjaCentral, DrunkenSlug, and nzbgeek, all paid. AnimeTosho is free and good.

You can with “Nicotine+”, which is an alternative client for soulseek.

DirectX is a Windows thing, so you’ll just have those calls translated to Vulkan under the hood (DXVK). You’ll probably get better performance from just setting it to Vulkan directly.

Edit: As some others say, for BG3 specifically, DXVK does a really good job. My personal experience is that “the best” option is very patch dependent. At launch Vulkan was best, then after a few patches did DXVK ran better, but personally I’m back to straight Vulkan, for no other reason than wanting to be a +1 in the statistics.
