I had type lag in Flex too.
It is like 100-1000 ms lag after I type a letter. If I type a bunch of letters at once, they lag then all appear at once.
I'm a VERY FAST typer and programmer, I need speed to keep myself focused.
What could be causing this lag? Could it be the autocomplete(which I don't use anyway) or something?
MS Word or Notepad have no type lag, and I have a gaming computer I bought last summer for Starcraft2, so its not my computer.
What are some settings I can turn off to get no type lag? I'm 381 hours into a project right now, going to publish in a few weeks. This isn't stopping me from programming, but I'd be much happier and more productive if I had no type lag.
Sometimes get 100-1000 ms after each letter, not always.
