display fusion 9.9 is causing very high CPU Usage when playing games.
There are other threads regarding this issue and i am not interested in installing several Beta versions to try one that works.

it is using 40% or more CPU. Closing the game does not work, as the usage remains high until Multi taskbar is disabled.
I am on steam so my key is not valid for 9.8.
I installed the 9.8 free trial version and there are no issues.

how can i install 9.8 with my steam license?

After +10 years of *perfect* DisplayFusion automatic updates, the update to 9.9 on Win7 is much much heavier in resources usage CPU/RAM/IO!

It is to the extent that I noticed this on a machine where DisplayFusion should not be able to be noticed and yet noticed the problem recurring over and over the last months ... having ended up implementing a *temp* fix of killing the process and re-launching DisplayFusion.

DisplayFusion.exe 9.9 has more CPU usage time than Explorer.exe ... much more I/O usage ... an insane +4GB RAM peak usage ... and seems to be "looping" over while possibly waiting on user input (User32.dll!WaitMessage) with the dialog/input not visible to the user

I'm going to call it for now:
- DisplayFusion 9.8 is the last *functional* version to be really run smooth on Win7, which is perfectly understandable since Win7 is no longer maintained!

Hopefully, this problem is only related to Win7

Thank you for the amazing software and all the included updates since 2010!
