Your display/graphics device can take up the most resources to run. Consider lightening the graphical load. Elaborate background screens, especially slide shows, will slow down your PC significantly. I know this is not a popular suggestion and you may not make this change. That's ok. Everyone likes the added appearances that make us happy. But when it come with a hit to performance? I'll take a little less mountain scenes on my desktop.
So, if you go toward the performance option over scenery, do the following.
1. Right click the desktop. (not on any icon)
2. Select Personalize
3. At the bottom, click on Desktop Background (solid color)
4. Pick a color you like and Save Changes.
If you don't like it you can always change back.
I admit, this will be boring, but your PC will be faster.
A sum of little things will add up toward big results.
Thanks for dropping by.
