That message has been in the software for a long time. Basically, SaT checks what Windows theme you are running. Scan Mode "DWM" only works when you are running an Aero theme in Windows 7 or Vista (on Win 8+, Aero is always on and can't be turned off). So SaT detects if Aero is on and alerts you appropriately.
What probably happened is that, earlier you were not using an Aero theme in Windows, and so by default, SaT chose the "PW" scan mode to scan your tables. You must have turned on Aero at the same time you were upgrading, if you say you only saw that message after the new install of 2.81.
You can download the old version 2.79 and verify this. Change your Windows theme by turning Aero on and off with different Scan Modes and you'll see SaT prompt you.

All that said, "PW" scan mode uses more memory than "DWM". However, perhaps turning on Aero in Windows has caused an increased load on your computer and maybe thats contributing. So, you could try turning off Aero theme in Windows, and then reverting back to "PW" scan mode, and see if that helps any.
