   fullscreen vs. windowed
  in the opengl application i''m developing, fullscreen or windowed mode have no differences in terms of performances or other issues. So i''m wondering what is the difference to use one of the two modes, i see in games you can select it too, but i see no changes at all.
  I think its just for the atmosphere. 3D Action shooters (for example Doom 3 with its horror scenes) are pretty much better to play in fullscreen.

Did you disable VSync when measuring FPS ? ;  yes, i disable vsync, but it is always the same, so i guess there is really no difference technically between the two modes ?   ;  No, there is no technically difference. You''re rendering in a frame buffer and therefore it doesn''t matter if this buffer is view in windows mode or in fullscreen mode (at the same resolution).   Corrailcorrail@gmx.atICQ#59184081 ;  You have the chance to have more control over the screen format though if you go into fullscreen. When you run in windowed, you have to use the current desktop bitdepth, which can cause performance problems if you have certain features enabled and the bitdepth is too low. I''ve noticed this happening with alpha blending. ;  I generally like the "windowed" feature because I can switch back and forth between applications without all that screen flickering.  A very good thing to look for if you are in a workplace. ;  I believe that in Fullscreen is faster. My WinXP, when i am playing games in fullscreen, doesn't load that messages: "You're connected" or "You have 30 days to register" or "Local Network on" and so on. I guess the Win doesn't process all the rest that isn't needed to show in the screen.In windowed mode, the border of the window has to be painted  [edited by - lobravo on August 3, 2003 5:33:21 PM];  Rendering in Fullscreen mode gives you more direct access to the hardware and is therefore usually faster.  It gives your application complete control of the drawing hardware for the time being.
