Printing to the screen slower in Windows 10?
Post by xyzzy on Mar 25^th, 2017, 2:24pm

Hi,

My new laptop has an i5 processor & runs Windows 10. My oldlaptop (4 years old) has an i3 processor & runs Windows 7. Both laptops are configured simirlarly.

As you'd expect, side by side the new laptop runs about 30% faster, including BB4W, except when printing to the screen eg:

Code:

      time=0
      for n=1 to 10000
        print n
      next
      print time/100

Takes almost 20 seconds on the new laptop, but only 12 on the old one? Is this a known issue, is it something to do with Windows 10, or is it just me?

Just curious, is all :)

I am guessing that your new machine has higher screen resolution. The time taken is a function of the speed it takes to update that window. If the window has more lines to update it will take longer. Just manually reduce the output window height when this is running and you can vary the times.
