  • True on the digit by digit code decryption. That I can forgive in the name of building tension and “counting down” in a visible way for the movie viewer. “When will it have the launch code?!” “In either 7 nano seconds or 12 years…”

    If they had been more accurate, it would have looked like the Bender xmas execution scene from Futurama:

    I did like the fact that they showed war-dialing and doing research to find a way into the system. It’s also interesting that they showed some secure practices, like the fact there was no banner identifying the system or OS, giving less info to a would be hacker. Granted, now a days it would have the official DoD banner identifying it as a DoD system.

    I remember with Windows 95, LAN Manager passwords were hashed in two 7 digit sections which made extracting user password from the password hash file trivial:

    Looks like it was worse than I remember. The passwords were first converted to all upper case first!

















  • Frametimes is the specific measure.

    <11.1ms for 90Hz or <8.33ms for 120Hz

    If the game, experience, or whatever breaches that minimum frame time frequently, then you can experience nausea just from moving your head around.

    It does require some sacrifices like turning shadows down a notch or two in some game engines and choosing additional visual effects carefully. Some visual effects require additional computation passes and can add the the frame time.

    A low latency CPU (like the AMD 3D cache CPUs) or a normal mid to high end CPU with fast memory with good timings helps quite a bit.

    The GPU should be capable of pushing the pixels and shading for the target resolution. Even with a 6900xt I’ve been able to comfortably push over 4500x3000 per eye rendering (enough to get a nice anti-aliasimg effect on my Pimax 8kX at the “normal” 150 degree H.FoV) in most games.

    Surprisingly, fidelity FX can help as well (the non-temporal version).
