Here's how to fix very slow display of text and pics on Powerpoint 2010 / 2007 slides on the screen, whenever you change or even edit slides? A big annoyance - it affects productivity, as sometimes Powerpoint becomes unresponsive and won't refresh, redraw or update the screen at all unless you change slides away and back (only a workaround, and slows things down).
Below is a step by step 'howto' solution to solve this problem of the slow graphics rendering in Powerpoint (others have solved it by changing to the Windows 7 Basic theme, this suggestion has the same effect, on my system at least, and changes the theme for you when you use the shortcut icon concerned to launch Powerpoint):
- Rightclick the shortcut icon that you use to start Powerpoint
- Choose "Properties" from the menu
- Now click the "Compatibility" tab (outlined in red below)
- Make sure "Disable desktop composition" is ticked as shown (also outlined in red, above).
- Then click "OK".
That's it. Worked for me on a Windows 7 Professional SP1 64-bit desktop, Powerpoint is a zillion times faster now. I hope it works for you too.
