|For the last few weeks I've been getting to grips with the way that deferred rendering works in an attempt to figure out why we don't get the framerate that we should. | |||
I've written up my findings here http://chateau-logic.com/content/deferred-rendering-rembrandt-performance | |||
It appears that vsync is causing problems; and I get a marked improvement in deferred rendering performance (Rembrandt) using the following flags: | |||
<code> | |||
—prop:/sim/rendering/vsync-enable{{=}}false —prop:/sim/frame-rate-throttle-hz{{=}}60 | |||
</code> | |||
Without these flags I get 30fps with nothing visible (/sim/rendering/draw-mask all false). With these flags I get 60fps when drawing nothing which is what I'd expect. | |||
What I'd like to know know is whether this makes a difference to anyone else - so I'd appreciate any test result FPS figures (with and without the flag) with graphics card and CPU posted here. | |||
I didn't figure out if vsync can be turned off per camera; but I'm 99.9% certain that this is what vsync is causing to happen on my configuration. | |||

FlightGear logos
If you want some graphic elements for your FlightGear-related site (for example a hangar or YouTube channel), please feel free to visit FlightGear logos for a repository of logos. And if you have some art skills, please don't hesitate to contribute with your own design creations.
Screenshots
The FlightGear project always needs screenshots, which show features that were added since the last release. These should be of good quality, especially in content and technical image properties. It is therefore recommended to use the best viable filter settings (antialiasing, texture sharpening, etc.). More info at Howto:Make nice screenshots.
