Creating a Window

Improving SDL Window Performance

What are some tips to improve the performance of an SDL window?

To improve the performance of an SDL window, consider the following tips:

  • Optimize your event loop: Only process events when necessary and avoid unnecessary computations or rendering in your loop.
  • Use hardware acceleration: Utilize the SDL_WINDOW_OPENGL flag when creating your window to enable OpenGL, which can help leverage GPU acceleration.
  • Manage your surfaces and textures efficiently: Minimize the use of SDL_UpdateWindowSurface() by using SDL textures and renderers for more efficient drawing and updates.

Here's how you could modify your existing window setup to use OpenGL for hardware acceleration:

#include <SDL.h>

int main(int argc, char** argv) {
  SDL_Init(SDL_INIT_VIDEO);
  SDL_Window* window =
    SDL_CreateWindow("Optimized Window",
      SDL_WINDOWPOS_UNDEFINED,
      SDL_WINDOWPOS_UNDEFINED,
      640, 480, SDL_WINDOW_OPENGL);  

  // Your rendering and event handling code here

  SDL_DestroyWindow(window);
  SDL_Quit();
  return 0;
}

This example shows the inclusion of the SDL_WINDOW_OPENGL flag to enable OpenGL features for better rendering performance.
