Hello all (srry my English). I used ClanLib and VS 2010.

PHP Code:
#include "main.h"

int Game::App(const std::vector<CL_String> &args)
{
    
Game Game;
    
Game.quit false;

    
CL_SetupCore sc;
    
CL_SetupDisplay sd;
    
CL_SetupGL sgl;

    
Game.Run();

    return 
0;
}

void Game::on_window_close()
{
    
this->quit true;
}

void Game::Run()
{
    
CL_DisplayWindowDescription    desc;
    
desc.set_size(CL_Size(1024768), true);
    
desc.set_title("Journey Sticks");
    
desc.set_allow_resize(false);
    
desc.show_maximize_button(false);

    
CL_DisplayWindow window(desc);

    
CL_GraphicContext gc window.get_gc();
    
CL_InputContext ic window.get_ic();

    
CL_Slot    slot_window_close window.sig_window_close().connect(this, &Game::on_window_close);


    
CL_ResourceManager resources("resources.xml");

    
CL_Sprite wall(gc"Wall", &resources);


    while(!(
this->quit == true))
    {
        
gc.clear(CL_Colorf::white);

        
wall.update();
        
wall.draw(gc00);


        
window.flip();
        
CL_KeepAlive::process();

    }

}

CL_ClanApplication app(&Game::App); 
Game - very slow and CPU - 100%, but if i remove "wall.draw(gc, 0, 0);" then all normal and CPU - 30-50%.

"CL_KeepAlive:: process(10);" - not solved problem
"CL_System::sleep(10);" - not solved problem

Info abount image:
Format - PNG
Size - 1024x768
Transparency - On

Help me, plz
