Second dos game I ever played was Doom on a 486. My mum was doing a tax return for the local bowls club, and the manager let me play Doom on their computer while she was going through all the paperwork.
A couple years later we got our own Pentium 133mhz and a copy of Doom and Duke 3D.
it will always be a problem with native games.
I think it was about 5 years ago, the Terraria team Linux dev left. Something happened that stopped the Linux build launching, and the native version was not playable until they got a new Linux dev in the team. Proton version worked flawlessly with more stable framerate.
As far as I know the native Undertale build is still unplayable. If it is working now, well it wasn't for about 6 years.
I see people get excited about native game builds, that's great but unless it's a very dedicated team that will update the game constantly it seems to be is no use.
I'm sure you'd be able to just type your delivery address when you order. Is there a reason you would need to have it in a document and then copy and paste it?
