Position indicator wrong

At some point in a group ride/race, the position indicator seems to be way off relative to where I see myself in the group. This also happens about the same time the fence starts to act up in group rides. In the pic you can see me at the back of the group, behind ride leader, but getting fence countdown and also the position lists me at 5th.

Running on Win10 with all latest updates.

Your distance is greater than those in front of you too… probably why Zwift thinks you are beyond the fence. Something isn’t right…

Jim, Can you put your log file of that ride in zwiftalizer.com and look at FPs and network issues. If you can post a screen shot of that we can look.

Here you are! Thanks much.

On what system are you running Zwift.

A average frame rate of 6 frames per second is extremely low. That may be the cause.

Here’s the laptop specs from the log folder.

I also upgraded the video driver. If there are any special settings you’d recommend that would be great. Thanks.
