Huh, interesting. I thought that the primary reason game devs use DRM these days is to specifically keep the first week’s sales as high as possible (since that’s the most easily available metric to judge a game’s success, and also the biggest moment of profit, as it’s usually only downhill from there). To see researchers actively suggest removing DRM after three months seems to confirm this idea further.

That’s not the actual GTA VI logo, but some fan creation. The logo in the actual trailer seems to consist of the standard GTA logo with a colorful “VI” in a bold sans-serif behind it.

These days “games I can play on Linux” is, like, almost every game released on Steam. Install Steam via your package manager or Flatpak, set up your account, and the vast majority of both native and Steam Play-based games will install and run very well. (The only thing worth noting is that while Windows and Mac versions of games are indicated by Windows and Apple logos, Linux native games are indicated by the Steam logo for SteamOS.)

In addition to that, there are free and open-source games that may be available for installation straight from your package manager (or Flatpak). Here are some:

• OpenTTD is a clone of Chris Sawyer’s Transport Tycoon Deluxe series, but with massive improvements to both UI and game logic. Run a transportation company, move people and cargo from one place to another, make money, expand, compete against AI or human opponents in online multiplayer.

• Xonotic is an original Quake/UT-style FPS. I don’t play it much, but I have friends who really enjoy it.

• “The Battle for Wesnoth” is a turn-based strategy game with gameplay reminiscent of console/handheld titles like Advance Wars, but redesigned to better suit PC gameplay. Has both singleplayer missions and online multiplayer.

Not necessarily – the story might have described a beta version of the OS, in which these interactions worked differently.

To be more specific: most often a game would run its physics calculation at the framerate it’s designed for, like 30 or 60 fps, and in case it displays with a higher framerate, try and interpolate the graphical data based on the physics calculations. It’s possible to make the physics run faster as well, but carelessly adapting things may make things go wrong (a good example is Quake 3, where your jump height changes based on the com_maxfps value).

A racing game that runs its physics at 60 frames per second can, at best, calculate time in 0.016666... second intervals. To have a precise 3-decimal-points clock, a game would need to run its physics calculations at 1000 frames per second.

(It is also worth noting that a game developer can try to interpolate a more precise finish time by looking at the last pre-finish frame position of the vehicle and the first post-finish frame position and calculating at what point “between the frames” the finish line would be crossed, but I don’t know how difficult and/or buggy actually implementing that would be.)

These days there are mods, such as SkyGFX, that let the PC version of GTA:SA match the PS2’s graphical effects, but these obviously rely on GPU improvements that didn’t exist back in 2005.
