@Georg Siebert Ok, so I've downloaded the track and spent the last 3 hours driving.
Here are my findings:
This track is unsuited for any kind of a race. Let me give you my reasons:
We plan to run a hour long race. Pit stops will be mandatory. This track can't support pit stops because of a bugged pit lane. esc+return to pits puts you at a considerable disadvantage.
There penaltie zones are extremely bugged. It's really bad. In some corners you can't apex correctly, because you will get a penalty.
There are
NO trackside objects to aid break and turn in points in the 2 most critical corners. (the fast right on the hill, and the slow left on the next hill before the main straight) The slow right isn't that bad, since you do have curbs and some lines to help, however due to the geometry of the track they are near impossible to see. I'd say a 3 screen setup will have a huge advantage here, because of the visibility)
--But the biggest killer here is the turn portimao (or turn 11 on this map
)
You come with high speeds into a breaking point on a crest. Not only do you battle severe oversteer, you have NO visual aids as to where to position yourself, leaving the driving here pure guesswork. Not good.
On a side note, the huge angles of the track, combined with huge breaking zones all across the track will in my opinion result in a complete clusterfu.ck. (think first corner of first lap)
So I'd like to ask the organizer of this race to reconsider moving the event to a different racetrack.
