So after deciding I was going to wait until the 64-bit Pi OS was tested and ready for use, I changed my mind and downloaded the beta and installed it.
It ran ok, though as with any Beta there are bound to be little glitches. There’s a survey where they are interested in what the PI is being used for and it showed UNDEFINED for my Pi’s serial number, though
worked fine and displayed it.
The display utility let me change my display to 75 HZ at 1920 x 1080 and then promptly crashed. After reboot though it was at 75 HZ.
My main reason for trying it out though, I was curious about development tools, particularly IDES. I had forgotten that code.headmelted.com, the alternative source for Visual Studio Code (my favourite) supported arm64 which is what the 64-bit runs. I was able to install VS Code from there without any problems.
64-bit vs 32-bit
32-bit has the memory limitation of 3 GB (in both Windows and Linux) whereas 64-bit offers any amount of RAM up to what’s available. It’s not that big thing with a 4 GB PI but with 8 GB it can make a big difference. This article (Sorry that the link is to an article on Medium.com which offers a few free articles then paid) suggests that 64-bit Debian (which Raspberry Pi OS is) is quite a bit faster than 32-bit. My impression is that it feels a bit snappier but that could be wishful thinking n my part!
I’ll put Asteroids on and see what fps I can get though that may not be a great way to compare them as the GPU plays a big part and I can’t see it making any difference, but I could be completely wrong on that. More as I investigate further.
