%%%version 2.66 (sub 1), revision b'55075:55077'. b'Release'
build date: b'2013-03-06', b'17:41:59'
platform: b'Windows:64bit'

I noticed this issue for a while, but was not able to nail it down. This is because this only happens once after starting Blender/BGE.

When the game should display text with a lot of different characters. The game gets a long delay within the next frame.
With the attached file I get a delay of more then 15 seconds for 39 (different) characters. (As said only the first time I run the game after starting Blender).

I guess this might be because the different objects/textures/materials needs to be generated and cached before showing. But 15 seconds delay is really long. Please have a look if there is a way to speed this up (maybe with a different design).

Example:
Blender Game Engine Started
currentTime: 2013-04-30 13:54:28.925996
set long text with 39 characters
currentTime: 2013-04-30 13:54:44.389796

0:00:15.463800 is way to much time
Blender Game Engine Finished

tested with 2.65 and 2.63 with the same results.

Thanks

%%%From what I know, yes, the texture needs to be generated when you first use the chars. However, testing it on my system, I could not produce the bad performance. This might be one of those GPU related bugs. What graphic hardware are you running on?

Can you adjust the resolution of the text and see if that helps? i.e.:

def setLongText(controller):

  longText = "abcdefghijklmnopqrstuovxyzäöüß?.,;:-+*/"
  controller.owner.resolution = 0.2
  controller.owner.text = longText
  print("set long text with {} characters".format(len(longText)))

Hi Monster,

Currently with blender 2.74 I didn't obtain bad performance either. See the following screenshoot:

Could you check it again?

Thanks.

Can't reproduce the bug, : 0:00:00.012916.
@monster : Can you retest with 2.76 ?

Closing the report as no feedback received and it seems that it is not a problem now.
