Re: Problem in fullscreen under Vista

Tech-Archive recommends: Repair Windows Errors & Optimize Windows Performance

I did too many of these ::GetSystemMetrics calls and I've had to go back and retrofit the
multimonitor support. Sorry I couldn't resolve the problem, but I've not tried high
performance graohics on Vista.

No idea about the frame rate, but you should make sure you can run in a
multimonitor
environment; your calls give the size of the primary monitor, which may
not be the monitor
that is running the application.

Hello,

A new problem appear only on vista (works under XP) - When i create a
popup window with an opengl context and when i set this window to full
screen, like that :


SetWindowPos(&wndTop,0,0,GetSystemMetrics(CX_SCREEN),GetSystemMetrics(CY_SCREEN),SWP_SHOWWINDOW);

It works under XP and totaly explode the frame rate under Vista (stats
fall down from 150 fps to 20 fps), i've made many test and found that this
problem does not appear when i :

- First get the work area with
SystemParametersInfo(SPI_GETWORKAREA,0,&rect,0)
- Set the windows position like that :
SetWindowPos(&wndTop,1,1,rect.Width()-2,rect.Heigth()-2,SWP_SHOWWINDOW).

Of course the window appear in full screen and the taskbar is not
cover
by anything, so the fps are again close to 150fps... I don't get it, each
time the taskbar is touched, there is a problem with the performances, is
it
a driver pb or is it soemthing else ?

Thanks
