  • There is a small yes, but not for that big of a gap. There is some minimal advantage, which is if the framerate goes above that of a screen(even at 30 fps caps, you might hit 31 occasionally depending on how it’s limited), you get screen tearing. Screen tearing is where new and old frame overlap causing the image to tear. VSYNC and other tech avoids this, but comes at a cost of a small delay in framerate.

    So the solution is simply to cap framerate either to a divisible part of the framerate, eg. 30 fps for 60 Hz screens, 60 fps for 120 Hz. You want divisible because if you create 35 fps, the frames will not be done at the same time as the screen is with showing a frame. Thus the need to have it semi matched up.

    But this is a rather big loss for a good screen, so you’d like to just cap fps to a few frames below the screen Hz. Modern technologies deal with that by talking better with the screen, so the screen shows a frame until given a next one. GSYNC and FreeSync are the ones that allow variable framerate without needing to match screen Hz and FPS. (There are some limitations, particularly they can be limited to some framerate ranges iirc, and if you go above screen refresh rate you’ll still have either screen tearing or VSYNC kick in with that extra delay.)



  • I’d expect a “Ultra-tier” fast charging station to have internal batteries (or perhaps supercapacitors or something like that) which buffer up from the grid. Eg. when not in use and over-night. Probably won’t last much into a day even with that, but we may see smaller buildings connected to charging stations that hold internal batteries to deliver faster charging than the connected grid can deliver.

    As long as there is demand and profit to be made, it could happen. The biggest cost is of course the batteries, but if solid-state batteries turn into reality I think things might be more cost effective. Especially since fixed position batteries aren’t subject to the same contraints as car batteries. Don’t need to handle vibration, weight is not a big problem. Key goals are lifetime value, energy density + and (dis)charging rates.

    Cheaper electricity during night might not be a thing everywhere or in the future, but small savings by stocking up cheaper during nighttime, gives better margins.
