I already dual boot CachyOS! In fact I spent a lot of time tweaking schedulers, power, undervolting the GPU and such for compute performance, but I think it’s well tuned for gaming too.
It’s just annoying because I beat the GPU into submission with tons of settings (as Nvidia is funny with Wayland), so its display out is totally disabled. It’s a lot to undo.
See, that makes it sound to me like you could probably come up with a setup that would do what you want, but that doing so would probably mean making it worse at some of the other things you currently use it for.
Which is where using an external drive for a third installation might be easier. Or at least easier to dispose of if you get sick of the project. But I am perhaps unusually lazy in that regard.
You raise an excellent point.
TBH I am both lazy, and a bit paranoid/afraid of dealing with Nvidia rendering issues (even if using my IGP for desktop work), but it would probably be fine and I'm... just being lazy and paranoid.
I don't think it would make it worse for compute work.
An external 3rd partition does sound appealing, though one quirk is that CP2077 does really like SSDs. I have a slow external SSD, but it still might muddy an A/B test.
If you have a desktop, these work great for swapping SSDs out. Get a pair and swap them out whenever you need/want to. You just need a spare x4 (or larger) PCI-e slot, which is pretty common to have. (Technically they work fine with a x1 slot, but then you are slowing the SSD down.)
I’ve got an ITX mini PC with both nvme and the graphics slot filled, heh.
