I run Windows 10 with Deskscapes 8.5 with K Lite Full codec pk, all works as it should,
and I run of course everyone of my Dreams and with low CPU usage.
There must be something else causing your problems.
Did you do an upgrade with windows 10 over 7 ?
You might have a codec problem too.
Maybe you should start over and do a Fresh Install with Windows 10
and re-install all your needed programs , starting with Deskscapes ?
Then as you install each program you can check that Deskscapes is
still working as it should.
Maybe you have program / or virus conflicts causing your problems
and higher CPU use than you should have.
Yes that's a lot to re-install everything but all should be right after.
You seem to be the only one with this problem, nobody else has
mentioned it .
Just my thought.
