Ghost, ghost trajectory, over game information, and telemetry can cause FPS to decrease.
If the FPS is too low the program will not be able to read the results and it will be perceived as a broken lap.
If the FPS will decrease during the use of these options, try to disable them in the program settings.
And close the telemetry windows, if they are open.
It is very important that during playing the game and working the program was not lags.
Otherwise, the program will say that the lap is broken because at some point it could not read the game data.
If you have lags, then before disabling these options in the program,
you can try to reduce the quality of the graphics in the game to improve FPS.
Some parameters do not greatly affect the graphics (for example, light trails), but lower FPS.
Check your PC, please.
When the program is running, Windows updates or other hard work should not be performed.
Otherwise, I repeat, there may be lags and the program will not be able to read the results.
(there may be other reasons, but you can handle this yourself)
You need about 200MB of RAM for program.
It is better that your computer supports multithreading.
You need a computer a little more powerful than just for the game.
