I started a Minecraft modpack called “Raspberry Flavoured”. It stood out to me because it boldly reworks many vanilla mechanics, while focusing on keeping a mostly vanilla playstyle. Villagers, the end, XP and enchanting, all completely removed. It reworks early game progression to use copper in place of stone, and copper has now become one of the most useful resources. It does have Create, so late game looks like it’ll be heavy on automation. The recipes are changed so early game still has mining, chopping and smelting. But it’s a breath of fresh air so far and the mods are incredibly well integrated!

I’m sorry to hear you’re having trouble!

Regarding the vainfo thing, at least on Arch, the Nvidia vaapi driver is a separate package. I’m not sure what the equivalent is on bazzite, but that’s likely why vainfo doesn’t show anything. And you should still be able to use nvenc anyways, which sunshine will choose before vaapi.

Is moonlight able to see the computer on your network? And in sunshine’s web interface under the “troubleshoot” tab, there’s a log. Does it say anything that might help?
