I took a shortcut when typing that, quoting the OP instead of further explaining. It is definitely possible to visualize 4 datapoints, but not 4 spatial dimensions. The only way to do so is to project to lower dimensions or take a lower dimension slice and display that. That works for 2D slices/projections of 3D objects because we already have a full understanding of 3D. It does not work for 2D projections of 4D objects, similar to how “flatlanders” couldn’t make sense of a 2D or 1D projection of a 3D object.
The actual cheaters completely bypassed the new anti-cheat in about 6 hours. They had to update their cheats a bit, but are otherwise essentially unaffected. Linux users, Steam Deck users, and people who don’t want to give a single game full hardware access, are all affected. None of those can play GTA:Online anymore, unless they mod the game to bypass the anti-cheat, which can be seen as cheating in itself, and could result in a ban.
The ddos attacks are likely being orchestrated by a small group of people or even an individual, it probably does not represent the vast majority of affected users.
