Control lag when online on a server

[Highwayman-Ed]

I'm having a ball with the Huey, and can hold a steady hover happily in single player, but things change when going out onto the internet for a multi-player session.

 

I have found that when I go online to a server and fly exactly the same mission that I have been flying offline, there is a slight delay in the control inputs and this makes hovering a lot more difficult to near impossible in some situations.

 

Ping to the server was around 250ms on a 20Mbps down, 1.5Mbps up connection, and flying other DCS modules didn't seem to suffer from the problem.

What's you're frame rate in single player and what is it on the server?

[Highwayman-Ed]

I'll check tonight, but visually the FPS was good with no stuttering or noticeable difference.

[Highwayman-Ed]

So my FPS offline was around 22, but on the server with only a 165 ping tonight the FPS was 35.

 

It seems that my control movements are more exaggerated when online than in single player. I'll investigate further.

Compaing FPS between online and offline is an unreliable affair, because some game/graphics settings can be pushed from the server. Of course the mission itself may also impact FPS. The only way to do a clean FPS comparison would be to run the same mission saved and then ran under the same settings between the two machines.

[Highwayman-Ed]

I've tested this on a few servers now and have the same result regardless of the ping rate and FPS with a saved version of the servers mission as well, although that's not the same in this example.

 

Here are a couple of videos that I recorded to show the contrast in behaviors.

 

Here is the Single Player offline flight around an airfield:

Single player flight is very smooth, control inputs are constant but subtle and you can see that it is easy to maintain controlled flight.

 

Here is the Multiplayer Server online flight around an airfield:

In multiplayer the flight is not smooth and you can see from the control inputs that I'm constantly stirring the pot to try and maintain controlled flight, and the control inputs seem to be much more exaggerated and laggy and it makes it almost impossible to anticipate the helicopters drift.

 

I'm hoping that it is a configuration issue that I have or something that has come up through patch to patch as I've come up through DCS World versions. On the same server at the weekend, other players in the squadron didn't have the same problems.

I've also noted another strange behavior in that when I set the trim in offline mode, the stick's center position is moved to where it was when the trim was set, but in Multiplayer it isn't and only seems to set a portion of that movement.

 

Fox example, when setting the initial take off trim I pulled the stick back and to the left to the approximate hover area and hit the force trim, but it only set the x co-ordinate and not the y!

 

I'm going to clean it out and perform a fresh installation of 1.2.4 later and see how that works.

Highwayman-Ed,

 

Just to be sure, are you using "sim" mode when you are in single player?

 

 

For example:

A player uses "game" mode in single player, connects to a server forcing"sim" mode and things seem very different

 

A player has "central position trimmer mode" in single player, server has it off

 

 

Just an idea

You might also want to try to clear our your input settings (at least joystick) in the DCS user files folder on the OS drive.

I'll check, you never know what creeps in, but I've always flows with the default 'Simulator' selection box at the bottom of the page.

Well it looks like the tinkering and modding of various files has come back and bit me in the butt. I've now done a fresh and clean install and taken the Huey out for a spin offline and online and she behaves more 'in the middle' of the two videos. Not as easy to control as in the first, but nowhere close to as difficult as the online video from before.

 

No idea what I had done to make it behave so differently, but at least it's consistent now, here is a video of how she behaves now when online:

Hi all,

 

I also suffer from what it seems to be laggy controls. The movement of the virtual controls do not match with the movement of the real life controls. When flying offline, everything is perfect. Near 1:1 controls, but when I host my own public server, the control lag starts. I lowered the scene on my server, but that doesn't change a thing at all. Still lag. Any thoughts about this? Thanks.

It would be intresting to host a server, fly a short flight in the Huey, and then land back somewhere. Then close the server, and grab the track and then play it. Would be intresting to see if it actually made a diffrence within the track. Maybe worth testing?
