For multi-monitor: use Wayland. For 2.5Gbps Ethernet NICs, they never work properly on any system in regard to performance, but I presume you are referencing the subpar Realtek NICs not connecting? Depending on the distro, you likely won’t have the driver and/or firmware package preinstalled to make it work.
A summary from its site and known technical details:
As for Windows 7, nobody should really need to install Librewolf anyway on such a device. No device running Windows 7 should have access to the internet at this point. If you are asking about compatibility intending this use case, you have bigger problems to worry about than your choice of browser. If you just need to view HTML files graphically, even Internet Explorer or an older firefox ESR will do.
Tbf to cloud sync, nothing is stopping you from using your own backup/restore service with your drm-free titles compared to the other features that Galaxy offers.
GOG has DRM for many titles: see Galaxy. As I understand it, it isn’t as pervasive as Steam, but is necessary if you want multiplayer on many titles or care about extras like achievements.
I am not sure if jest, but you could always take a few seconds at protondb to see that yes, all of those games do in fact run on Linux. Forza in particular seems to have issues for some users, but everything else works with minimal hassle.
VideoLabs is made up of many of the same contributors of VideoLAN, including Jean-Baptiste Kempf themself. It is arguable that this is in fact Unity banning VideoLAN’s VLC bridges for media playback in Unity.
You use Steam for games on Linux primarily. Independent native games exist as well. Many Windows-only titles will be best run through Proton: Valve’s modified WINE bundle. Other store titles can be configured to run through WINE or Proton via apps like Lutris or Heroic (GOG, Itch.io, Epic Games, etc.).
