Output update rate with UDP

[JFM]

Hello,

I have set up the output of some properties with an UDP socket. The problem is that the update rate is far from the one I have programmed, say 10 Hz, and closer to the (low) frame rate that my PC is able to achieve (4-5). Is the output rate limited by the frame rate, or may be the problem is something different?

Regards,

It is limited by the frame rate.
If real time progress is not required you can set --prop:double:/sim/max-simtime-per-frame=0.1 to make sure each frame never exceeds 0.1 seconds of simulated time.

In that case the controller should run at the same rate (non-real time). This is another possibility. However, I have found that I was not using the Nvidia card in my laptop. When I managed to enable it for FG it could reach at least 20 FPS or more, so now there is not much of a problem to control at 10 Hz, in fact I did. I managed to stabilize the Cessna and follow a heading with a relatively simple controller. May be for faster planes or more aggressive maneuvers I would need a higher rate, but not for this. It would be nice to be able to get data at model update rate instead of frame rate, anyway.

By the way, enabling the Nvidia card is tricky in my laptop; I finally had to right-click on the executable and select it every time. I tried to use the Nvidia control panel without success...

Thanks,

it's probably optimus related, right ?
