Some Apps very slow to load

Hi,

Due to issues I had upgrading an older to PC to the latest Windows 10 version, I decide to bite the bullet and buy a new new PC. Maybe I bit off more of that bullet than I could chew.

I've upgraded to a DELL Optiplex 7090 with a DELL Ultra HD monitor (3840 x 2160) running Windows 10 (20H2). Initially everything seems OK but noticed that some apps (in fact a lot of them) I installed were appearing with blurred text. Most of these (like Office apps) can be fixed by using the app properties/compatibility tab and adjusting the DPI scaling so no optimisations occur, or if that isn't available, using the Application Tools while the exe file is highlighted. A nuisance as each app needs this done individually, but doable.

However another problem I've found using this high resolution monitor is some apps can take up to 5 minutes to open! Apps like all Office ones (Outlook etc), Adobe Lightroom and most others work just fine, opening immediately and working just as well on the new PC as they did on the old one. Some apps like PLEX and iTunes however take around 5 minutes to open. When I launch these apps they appear in Task manager immediately but don't display anything on screen for around the 5 minutes, they then work OK.

It's difficult to try and understand where the fault lies. As this only happens on the new PC, with the 3840 x 2160 display, I'm not sure if the problem is with...

  • Is it the app itself, that is they are having difficultly with displaying on the high res screen.
  • The video driver that came with the PC (Video is Intel Iris Xe Graphics adapter)
  • A Windows 10 issue

I noticed that the video driver Digital Signature is "Microsoft Windows Hardware Compatibility Publisher" (Driver date 28/10/2020, version 27.20.100.8395). As this suggests some compatibility stuff is going on with this driver I thought I'd ask this question here first.


Does anyone have any thoughts about why some apps are taking so long to load?

Thanks
