Did you do any benchmarks?
RA2 might benefit from doing that too. And it'd certainly solve the screenshot issue. Otherwise one could do a blit from video to a system memory surface.
Quote:and rewrote the screenshot function to write 16 bit BMPs. This makes the lock itself cheap, and the screenshot writer only needs to copy data from the surface without recompressing it in any way. It still feels slow to me, but that might be because I'm running 1920x1080.Saw that one already. My code writes PNGs now.
Search for Game_MakeScreenshot in http://svn.renegadeprojects.com/filedeta...rfaces.cpp for how it was done.
