Solved

2 problems

1. there are massive lags in every race of our league, real issue of over heating tyres etc

2. when using boost i use like 20% (lvl 17) and then i gain 1 sec on the guy infront and he didnt use boost nor was in drs 

Hi Bertus, do you know which race the lags started happening with?

no not sure, couldnt attend all the races but the other people in my league can tell

I think the developers already have an idea of the first problem. The second problem may be a side effect of the first problem.
