  • DLSS is machine learning model trained by Nvidia to invent information to rendered game frames. In general there are two ways:

    • You have two frames of game, model makes up third frame between those two frames, to make game run smoother. This has down side that input lag (you press button and it happens on screen) gets longer. But it increases your FPS (frames per second), which looks smoother.
    • model makes up extra detail to the game frame. Previous versions have mainly being AI upscaling. Game renders in smaller resolution (less pixels), and then it is made larger, and model smooths and makes up details that originally wasn’t there.

    Both of these have same downside, they can cause inconsistency between frames, and have flickering etc.

    This is what DLSS 5 now takes to much more heavier “AI filter” level, because it is not anymore upscaling, but it now can add much more detail that originally wasn’t there. But because the model doesn’t have memory, it must always cause issue that the output will always be bit different. Curious to see how they have overcome that, or is it really so that with DLSS5 with every cutscene, the main character looks different.
















  • GPT-5 without “thinking” mode got the answer wrong.

    GPT-5 with thinking answered:

    Here are the 21 US states with the letter “R” in their name:

    Arizona, Arkansas, California, Colorado, Delaware, Florida, Georgia, Maryland, Missouri, Nebraska, New Hampshire, New Jersey, New York, North Carolina, North Dakota, Oregon, Rhode Island, South Carolina, Vermont, Virginia, West Virginia.

    It wrote a script that verified it while doing the “thinking” (feeding the hallusinations back to the LLM)
