Sorry Ant, it just seems every race GT is shouting at you but you seem oblivious! I was watching from the race monitor and it was more than lag, as the prediction algorythms showed you off track then back on track and probably contributed to the accident with SRW i saw in praccy.
I got overtaken I think in practice by an invisible car. I had a red triangle on the track view but no car on track. I've seen this behaviour before. Is it this lag issue or another player who's joined since I went on track. I know GTR2 had invisible cars in the latter.
I'm pretty sure that would have been Anty as I experienced similar thing during practice. When players join in RR they are loaded straight away which usually causes a pause/stutter for drivers on track. This means lost time for that lap so it is important that all drivers join
before quali session. At present there is no option to load cars only in garage but this has been flagged up as an issue.
