Timing screen is slow and does not reflect real time⁠›››

Relatively new install of both Windows and iRacing and ATVO, I'm seeing the timing screen being really slow. Track maps update maybe once every 10 seconds. timing data is taking forever to update, and the program seems generally SUPER sluggish. I'm really not sure where to look to get this program responding. I used this program about 16 months ago until recently, and it was very responsive and easy to use. I'm not sure what really has changed. Any advice?

Is this a common problem that happens all the time, or was it one particular race?
Are you using NDI? If not, please check in your settings if it is disabled. If it was enabled, can you check if disabling it fixes the problem? (Restart ATVO after changing the setting)

Upon investigation, it looks like everything works as usual without NDI being enabled. Hopefully the new NDI in development will resolve this. I was so happy to see NDI integration with ATVO!

Yes, the old NDI can slow down ATVO considerably. The new NDI Recorder does not. You can already try it on the alpha channel, but you need the insider build of Windows 10 to get transparency to work.
