You need 2 hook processes because each process can only hook processes that are the same bitness as itself. We care about performance as much as you, we optimize all of our code as much as we can. Everything that DisplayFusion is running needs to be running in order to function. ]]> https://www.displayfusion.com/Discussions/View/df-v510beta13-why-dfhookappvista3264exe-used-on-windows-8-x64-professional/?ID=64f7268a-37b7-46bb-95a8-67b53895808e#8 Tue, 10 Sep 2013 03:55:51 GMT Binary Fortress Software https://www.displayfusion.com/Discussions/View/df-v510beta13-why-dfhookappvista3264exe-used-on-windows-8-x64-professional/?ID=64f7268a-37b7-46bb-95a8-67b53895808e#8 DisplayFusion Thanks for your reply. To be more precise, I don't understand why there is a 32bit process and a 64bit process. All application I have installed use either one or the other, not both.
Also, what is the DF service doing? Is that something I can stop?
Yes, I'm desperately trying to optimize my laptop perf!

For performance reasons there hook processes need to run outside of the DisplayFusion main process. If you have any DisplayFusion windows open (like the Settings or Wallpaper windows) you'll see a 4th process. I hope this answers your question. ]]> https://www.displayfusion.com/Discussions/View/df-v510beta13-why-dfhookappvista3264exe-used-on-windows-8-x64-professional/?ID=64f7268a-37b7-46bb-95a8-67b53895808e#6 Sun, 08 Sep 2013 19:56:55 GMT Binary Fortress Software https://www.displayfusion.com/Discussions/View/df-v510beta13-why-dfhookappvista3264exe-used-on-windows-8-x64-professional/?ID=64f7268a-37b7-46bb-95a8-67b53895808e#6 DisplayFusion Hi. With regards to the previous messages, I was wondering why there are 4 processes running all the time for DisplayFusion? I'm using DF Pro 5.1 with win7 x64.

I'll change our build process so it produces different filenames for these hooks. ]]> https://www.displayfusion.com/Discussions/View/df-v510beta13-why-dfhookappvista3264exe-used-on-windows-8-x64-professional/?ID=64f7268a-37b7-46bb-95a8-67b53895808e#4 Tue, 30 Jul 2013 05:26:48 GMT Binary Fortress Software https://www.displayfusion.com/Discussions/View/df-v510beta13-why-dfhookappvista3264exe-used-on-windows-8-x64-professional/?ID=64f7268a-37b7-46bb-95a8-67b53895808e#4 DisplayFusion Or name them just DisplayFusionHookApp32.exe and DisplayFusionHookApp64.exe for non-XP systems. In a manner of speaking, it looks "spooky" to see "Vista" lurking in RAM on Windows 7 and Windows 8.

I am curious as to why DisplayFusionHookAppVISTA32.exe and DisplayFusionHookAppVISTA64.exe are used on Windows 8 x64 Professional (VISTA being the operative here).

Should there be a DisplayFusionHookAppWin832.exe and DisplayFusionHookAppWin864.exe? ]]>
