Getting better all the time , performance now seems good . no stuttering & no FPS loss .
Colors don't seem to work correctly ..only purple working for me .
I would like to see the optimal in green all the time .. and your current sector in red for below optimal and green for faster than optimal.
for me this would make it a little easier to differentiate between the numbers whilst racing as they are quite small when your concentrating on the track.
Good job though and its getting better
