  • AMD Mobile chips tend to use a “half-generation” refresh of their main GPU architecture. For example the rdna3 Desktop line is gfx1100, gfx1101, gfx1102 depending on the model. The new mobile GPUs in the strix point CPUs (I. E. the new framework models) have gfx1150/gfx1151 denoting their rdna3.5 refresh.

    The UDNA is in reference to amd stopping to have two lines of internal architectures: RDNA for graphics (Radeon cards) and CDNA for compute (like the MI line of chips) and instead have one architecture for both, labeld UDNA.



  • Yeah I really want to see the numbers on this.

    It seems to be a absolute breaking issue for them, suggesting a actual noticeable delay. So it should at least be one frame (on 60hz display) of additional latency compared to x11. Especially since there is earlier work Using a Click based measurement setup showing no such delay.

    The pi is either emitting a mouse move or detecting one on the physical device and measuring the time that passes until the photo diode/resistor (not an led) is detecting the cursor to move away.

    It’s essentially the same setup you would use to detect input to photon latency if you don’t have a high speed camera.

    Edit: Ah no there’s another setup with a pi pico in there… Yeah it’s binding and LED Lighting up to a button press to have two visual indicators (LED and Cursor Reaction) you can measure using a high speed camera. Them only having a 90fps phone camera makes it means the measurements are only in 11ms increments though.









  • Most of the stuff on GoG should fit the bill. You still can use it as a website to shop for a game and get a installer exe for it. Without any additional launcher.

    As far as documented network go, I’ve never seen more than games listing a couple of ports for servers, never anything like ips or actual network protocol descriptions. I guess anything with user hostable dedicated servers should be fine.

    Problem is that those old games have very low online population, so I’m not entirely sure how much “casual comraderie” you’ll find.



  • That’s an interesting approach. The Traditional way would be to go by game score like the AI Mario Projects. But I can see the value in prioritizing Bullet Avoidance over pure score.

    Does your training Environment Model that shooting at enemies (eventually) makes them stop spitting out bullets? I also would assume that total survival time is a part of the score, otherwise the Boss would just be a loosing game score wise.

    Bringing more modern tools and features to existing large code bases is “destroying his reputation”? Bjarne and the committee is constantly extending and modernizing a language with code bases older than me. Yes that means the old stuff has to be kept around but that is the price of allowing existing code to migrate gracefully instead of just throwing it out of the window. There is a problem with some missing rails to enforce current and saver techniques but Bjarne is not denying that.
