seems 80% of servers are this circuit, is this correct or theres something wrong with mysettings?

Most of those servers are Demo servers.

Do you have any filters turned on? I wouldn't know, I never use the ingame serverlist, as I only race on a handful of servers, which I just type in manually.

EDIT: what Töki said makes much more sense

it is because of the new patch, it combines all of demo, s1 and s2 servers together, so that the demo users can go on S2 servers if they have just demo content

problem solved, now i find much more serers, theres even a permanent oval

congrats lerts have fun
