I'm working on the RA2 screenshot code. Most time appears to be spend in lock(). lock() takes about 882 ms in my case (1600 x 1200, Q9450) while the entire function takes 925 ms. So the PCX part appears to be trivial.
How did you avoid this in the YR code?
I guess lock() copies the primary surface from video mem to system mem, but I've no idea why it's taking so long.
Nevermind, it's my loop that transforms the data from 16b to 24b that's taking so long. No idea why though. The memory returned by lock() is already in system memory, right?
