General discussions / Software blitting performance SFML/SDL

« on: November 23, 2010, 08:26:17 pm »

Hi all,

thanks for your input!

Yes, I meant software->hardware rendering, if that's the way to put it. Sorry if that wasn't made clear; english is not my native language.

And of course the vast majority of runtime is spent in the actual algorithms with ray tracers in general, but I wanted to look in every direction regarding possible optimizations. But if you think the differences will be negligible, then perhaps I shouldn't spend too much time on this matter - and migrating the backend (my current implementation is using SDL) would certainly be some effort, too.

Thanks again,

C1

Hi all,

I hope I'm not beating a dead horse here :wink: , but unfortunately I didn't find what I'm looking for by using my google-fu, so hopefully you guys can help me:

Did anyone of you benchmark of SFML's software rendering speed (i.e. simply blitting a 2d surface/pixel array to screen) vs. SDL on an average desktop/laptop system?

The thread at http://www.sfml-dev.org/forum/viewtopic.php?t=43&start=0&postdays=0&postorder=asc&highlight= is about rendering sprites and text, not exactly what I'm looking for (think ray tracer here).

Thanks for your help,

C1
