I collected my car last Wednesday (7th August) and have been through an exchange via email with Tesla on whether or not I actually have the FSD HW3 computer. My car records videos in H264 not H265 but they tell me I do have HW3. I also took a photo of the computer part number (under the glove box) The parts list here https://epc.teslamotors.com/#/systemGroups/47362 seems to indicate I do have HW3 and Tesla support europe tell me that there is a lot of confusion with codecs at the moment. It's possible and plausible that in software 2019.28.2 they are now emulating HW2.5 and/or have reverted to the older codec with HW3 to make software releases easier across both HW2.5 and HW3. I have created a google sheet to try and get more data of model variant software version and part no they have here Model 3 HW3 computers Hopefully more data will help make sense of whats going on.
