I've noticed with my own projects using SDL switching to fullscreen often gave a significant performance increase, SDL is somewhat famous for reduced performance within a windowed application so the switch might be worth it if it's possible.

be sure you are converting all your surface's to the screens format BEFORE you blit any of them.

Quote: also, in OpenGL, try using vertex arrays. stuff all your tiles into one vertex array with all the texture coordinates / positions and call glDrawArrays(). this should give a nice increase (depending on if your fill rate limited or geomoetry limited).

also, try running the game in fullscreen. this should give a nice boost in OpenGL. not only that, but try running the game in 16 bit color, in fullscreen. this should definetly show a nice boost in frame-rate. (again, depending on if its fill-rate or not, im betting it is though).

also, if you don't want to use vertex arrays, at least try to make GL function calls a minimum. that is, you might be doing something like this:

for each tile   gltextcoord()   glcolor3f()   glBegin()   draw_quad()   glEnd()

instead, do this:

gltextcoord()glcolor3f()glBegin()for each tile   draw_quad();glEnd()

As for your windows demo here are a few things:
* The back in options does not work
* I'd suggest making an -apply- button so when the user changes the display mode, they are not looped through each display.

Quote: * I found a bug, when input grab is on and you choose software mode, the game works nice and fast, however when it is off and you choose software mode, the game runs slower than a 1 legged sloth, I think it hits fps of below 2. I dont know if this is a windows problem or game, but it happens on my comp.

well... unless the map is dynamic, why are you re-drawing the mini-map each frame? why not render the mini-map a single time, onto an SDL_Surface. then, just blit this surface each frame (in software). in OpenGL, just turn this surface into a texture, and render the texutre onto a quad each frame. then, the only thing you have to render with the mini-map is the little dots that represent the characters. if you need more details, just ask.

Just a quick question but how do you draw text to the screen? I have noticed that drawing/updating text every frame can be pretty costly. It usually isn't a problem for just displaying the fps but if you can draw it to a surface first and only update that surface with the new fps once every second or 2 instead of every frame it might help with the frame rate. Like I said, I don't know how you are rendering your text but it has been my own experience that text is a big performance hit. I don't have access to a decent machine so I am stuck with my 500MHZ AMD machine to develop on so the little things do get noticed on my machine :)
