Title: libSDL apps, tried but there are problems
Post by: iamasmith on October 06, 2004, 04:46:06 pm

Hi, thought I should start this thread after compiling supertux and finding that it's way too heavy on both memory and processor to run on Qtopia.

I'm suggesting that you tag your apps on here that you have already tried and had problems with. Maybe if it's not a critical lack of power type issue then someone can help out.

Actually if we could get this pinned then we could use it as a reference to what's been tried and doesn't work... I'm sure someone has tried supertux before !

So, next posting starts the thread...

Supertux, compiled on desktop, tested with zports libSDL and libSDL_mixer + gnurou libSDL_image.

Starts, seems to run but basically locks up the whole Z, very slow, very memory hungry. Almost immediately Qtopia pops up with a message saying that the application is running slowly and should it be killed.

Tested on SL-C860 with Cacko 1.21b

You probably have to force it to run in 320x240, i doubt anygame will run that smooth in 640x480 without any ati drivers optimisation. (that nobody have).

Especially if its a fast moving game

Right. I have a small and simple SDL demo, but it runs only between 5 and 10 fps on my 760, mostly because it is in 640x480 I guess...

There were several issues with SuperTux 0.1.2, which caused it not to run properly on a zaurus SL-C860. Most important was a memory leak in the lisp_reader and second was the fact that it used a lot of floating point arithmetic (ARM has not floating point unit). I managed to fix these issues and now have the game running at around 12 fps and 40 MB memory usage.

Cheers,

P.S. SuperTux only runs in 640x480, so no scaling down...
