    Why are we all not promoting DirectStorage to the devs, engineers, or coders? I conducted a decompression test with a 3 GB file by the GPU in less than 7 milliseconds. That is unreal!

      In my opinion they are doing it, but usually development is not as fast as x ads

    Hey MS where is Windows HDR calibration??? We are waiting since feb for almost half of year and its still not there! Is it so hard to port couple of test images and color profile calibration routing from Xbox Series? You even removed basic calibration settings for HDR from Win 11, so there is absolutely no calibration available! Release already whatever you have in next dev update for Win 11, even if ts beta and unfinished. Beta better than nothing!
