This message is mainly from the game thinking Windows’ paging file/swap aren’t large enough. I’ve seen it default to static sizes, to Windows controlled and small, and to (what I think is best) Windows controlled and its the size of your RAM.
When I last played, I was using w11 from a custom .iso install. It was static set to like 2gigs, and setting it to match my 16gigs of RAM made the warning go away.
Most people don’t know, but a lot of programs are designed to use an amount of Windows’ paging file, and/or a Linux swap partition or the newer zram.
Still don’t have it on 6 pro.
