DD and I just talked about this, and we'll be organizing a test on the server on this coming Saturday.
The objective of the test will be to find out whether there are some unforeseeable FPS issues that come with having many clients connected to the server on a track like this. Everyone is welcome to join the server for this test, we will most likely run the test without a password on the server. Hopefully at least 30 people will show up so that we can emulate race weekend conditions.
The plan would be to do a 15-20 minute practice session where the drivers are out on track so that we can gauge the server conditions. Then we can do a few 10 lap fun races (or one longer race), so that the participating drivers can hopefully get something in return for their time spent.
Since F1 qualifying is also on Saturday, this test would be scheduled around it, either at 12:00 GMT (well before F1 Qualifying) or at 19:00 GMT (an hour or so after F1 Qualifying). A decision on the time of the test will be made by Friday.
Regarding holes in the guardrails, our track team will try to fix these, but since we only have one person who does the actual editing of the tracks, it is unknown whether he'll have time to do all this.
In any case, should we need to change tracks, we will do so on this Sunday at the latest, to ensure that everyone would have enough time to get used to the other Monaco version.
