UDP Motion Delayed in Win 10 2004

[PEZZALUCIFER 1]

As of Windows update 2004 udp motion telemetry is delayed by around 3 seconds when using delay=1

We are also using extradata=3 if that's important..

When using delay=2 the motion isn't delayed however the motion is only 50hz and low resolution. :(

We have tried f1 2020 also and it doesn't appear to have this issue.

Windows 10 1903 doesn't have this issue, and delay=1 works correctly.

This has been observed on multiple different pcs, using latest Simfeedback software on Windows 10 2004. 

 

Cheers.

The possible cause for this issue.

Interesting, though far too technical for somebody like me to comprehend 🙂 

 

Do you have a tldr, and is there anything that can be done on your end to help correct this?

The current workaround is to use delay=2 in the hardware config for the game.

Which works but its no where near as good as delay=1 was on windows 10 1903. 

If the timeBeginPeriod change in win 10 2004 is the cause then probably the only way to fix it will be a code fix in the game.

Your programmers would know what i'm talking about 🙂

Thanks.

Thanks, I'll pass it on.

I can confirm I do have the same problems too , delay=1 in the hardware config for the game make my motion simulation 3-4 sec latency now :(
I did change for delay=2 but it's not that good

 

interesting fact is F1 2020 work fine it's Dirt rally 2 and Dirt 4 that have this problem

thanks

Alright, this Dirt Rally 2 lag issue is a confusing one. 

I made my own program to read the codemasters telemetry and it does the same thing with delay=1, so it's not the simfeedback provider.

My accuforce wheel uses custom_udp, with delay=1, which works fine with the wheel, no lag whatsoever.

Soooo maybe the issue is specific to the default udp + delay=1

I'm going to have to write another test provider for custom udp + delay=1 to confirm.
