I worked with a guy who had a flag with the Arch logo and his Arch forums username on it hanging above his desk.

womp womp :)

I don’t think the point is that swap is critical. Whether that is true will depend on your workload and hardware. But the point is it makes memory management better and more efficient. Whether you notice a difference in performance or not is again dependent on your workload & hardware. I personally see no reason to not dedicate a couple gigs to swap even with lots of memory on a personal system.

For what it’s worth, I’ve used Nvidia cards for at least a decade without any major issues. Mostly on Arch, though I do vaguely recall needing to fiddle with it more on really old Ubuntu releases.

If you have enough ram, you don’t really need swap at all.

This isn’t really true. Swap is important for things other than acting as a memory reserve. Even if it was only used that way, it can still improve performance by paging out unused memory (such as from application startup that then isn’t used).

There are other benefits too. This link goes into details.
