v13 - high CPU usage?

[cjones8]

I have just updated to the latest release of v13 and updated my java from jre8 to jre21 (as required for v13).

Now when I run v13 I have v. high CPU usage with the fan running constantly.

Windows 10 task manager show Ancestris using 65-70% CPU and over 600Mb of memory with "very high" power usage. All other processes are showing less 2% usage. As soon as I close Ancestris everything drops back to normal and the fan stops.

Is anyone else noticing increase resource utilisation with the new version?

jre21 is not mandatory, jre17 is.

Some users have noticed more CPU usage with Java 20 or more.
We don't have any explanation for this over-usage.

Thanks

I picked jre21 because it was the recommended version as the current LTS version.

I'll try 'downgrading' to jre17 and see if  that helps reduce resource/cpu usage.

UPDATE: Just uninstalled 21 and installed 17. On initial run it seems much better. CPU load back down to less 2% and no heating issues / fan constantly running. Looks like jre17 is the way to go if anybody as similar issues with jre21.
