Native ARM support
Hi Nick
Any plans to support Windows ARM? The battery life and performance of the latest snapdragon X processors is perfect for our nautical use case
Regards
Paul

Re: Native ARM support
I have thought about it and it may happen one day, although I suspect it will be a lot of work.
One issue is that some of the third party systems used by Exp are x86/64 only, so it is more work than just changing the target.
It isn't a priority though as apparently the x86/64 apps work ok on Windows on Arm.

Re: Native ARM support
Expedition 12.3 now has native ARM64 support.
Note that this does not support Navionics or C-Map as both are x86/x64 only.
If you do need Navionics or C-Map 4D, then the normal build is recommended.
We do not recommend C-Map MAX on ARM64 as performance will the terrible.

Re: Native ARM support
I just wish there was as easy and inexpensive way to get ENC charts as 4D and Navionics make it for the waters the cover RORC races.
When I've tried to put together coverage that matches the UK/|Europe coast in ENCs it was MUCH more expensive.
Does anyone know a trick? (I'd love to move my boat systems to ARM64)

Re: Native ARM support
I have the ARM version installed and running on my Macbook Air M2 running Parallels with Windows 11 Home and so far so good.
Am I correct assuming that the ARM version will work better for this setup than the standard version?

Re: Native ARM support
Sparky. I looked at Arm64EC, but several of the libraries Exp uses didn't like it which meant there wasn't a lot of point in a build and it made sense to go fully to ARM.
4D only has another 2 years until EOL btw.
I don't know enough about Parallels on Macs to know how it works for ARM64 code. Hopefully the performance is better.
Also, I am thinking of making this the last 32 bit MAX build. 32 bit support is increasingly problematical and people should have moved off MAX charts many years ago.

I use ENC's from chart world almost exclusively. I get greater assurance of the information as they are proper ENC charts, not just another companies re-rendering of the data. Yes, a bit more expensive, but you get what you pay for, and I typically rent for just 3 mth for the areas I need.

I had an email from a user this morning who commented that the ARM version is a lot faster and uses less CPU on his Mac under Parallels for both routing and charting.
As an addendum to that, the next release is a lot faster for ENCs and RNCs. There is more to come with ENCs, but it depends on finding a spare month.
