Window / Re: Duplicating main window output to second window

Yes the other option is indeed drawing all drawables twice, in this application it seems the performance (fps - fraps) was even worse.

After some unrelated testing I found out that the decrease in performance was because the window type was sf::Style::None.

sf::Style::Default/sf::Style::Fullscreen resulted in the original performance.

I'm not sure if it is the result of the operating system (Windows 8.1) or the graphics drivers (latest).

Is this expected?

Window / Duplicating main window output to second window

« on: October 23, 2013, 12:55:00 pm »

Hello All,

For a project I am writing, I would like to create a duplicate window. For example: everything  will be drawn to the main window, and the duplicate window at an arbitrary position and size will simply replicate the output.

I haven't been able to figure out if there is an efficient way around this, currently everything is drawn to a render texture then to the two windows at a ~30-40% reduction in performance.

Any ideas on how to do this without a loss of performance?

Gr,
