Succeeded in replicating problem on Desktop. (Running on Windows Vista Home Premium edition, Service Pack 2, Intel Core i7 at 2,67 Ghz and 6 gigabytes of memory).
Having read other thread about lag and CPU usage I kept an eye on the CPU usage and noted those numbers. For what they are worth here are the notes I made during these tests:
[*]Testing testing testing to see if there is any slowdown at all…
No lag. Usage 1% CPU
[*]Testing again after adding description via Inspector. No lag. Usage 1% CPU
[*]Testing again after using the corkboard to add description no lag. Usage 1% CPU
[*]Trying again after adding several documents, but before changing anything else. CPU 1%
[*]Trying again after adding description via notecard. Somehow there was a big spike in CPU but I have no idea why it showed up. No lag. CPU 1-2% 1,96 memory.
[*]Changed label of the second scene to concept while changed to corkboard mode. No lag. CPU 1%
[*]Changed status of second scene to revised draft. CPU rises to 3-4 % while just hitting keys quickly at random and to 5% while holding backspace to get rid of the text.
[*]Changed title of second scene using the notecards in the corkboard mode. CPU usage while “mashing” 5% same while holding backspace to erase.
[*]Added title to all but one of the scenes. CPU usage rises to two percent while typing normally. CPU usage 6% while mashing. 7% while holding backspace pressed.
[*]Added labels to all the documents in the draft. CPU usage 2-3% while typing normally. CPU usage 7-9% while mashing keys. Topping out at 9 percent while holding down backspace.
[*]No changes but have gone to the draft corkboard view a few times. CPu rises 3-4% while typing at my normal speed. CPU usage 6-9% while mashing keys, 8-10% while holding down the backspace key.
[*]Gone back and forth between Draft and the second scene document an additional number of times. CPU 3-4% while typing at normal speeds. CPU usage 13% while mashing keys and the same while holding down the backspace key.
[*]Changed view of draft to text view and clicked back and forth between this and the second scene about ten times. CPU usage tops at 5% while typing at my normal top speed. CPU usage 13-14% while mashing keys and 13% while holding down the backspace key.
[*]Changed the draft document view back to corkboard view and went back andf forth between that and the second scene about ten or so times. CPU usage tops at 7% while typing at normal speed. CPU usage 14% while mashing keys for extended period. IMMENSE lag before text shows up and only two lines of characters show up. CPU usage of 14% is constant (except for a brief spike of 21%) between the time I stop pressing keys and the time the text shows up. CPU usage 14% while keeping backspace pressed to delete the “mashed” text.
After this test I closed the project and opened a new blank project. Without changing anything else I just clicked back and forth between draft and the untitled scene under draft in the binder a number of times. CPU usage when just pressing keys quickly 7-8% about same when erasing the text again by holding down backspace.
Then, without any changes I clicked back and forth between draft and the untitled scene several times again (10 to 20 clicks?) and CPU usage rises to 12-13% when “mashing” keys and 11-12% when keeping backspace pressed.
Hope this helps!
