I'm not a FSR member, but I have to say that rF2 is ready to be used, I think the lack of tracks is really the impediment, but not the physics engine or big bugs. Performance isn't bad now, I have a 550€ PC (nothing special, midrange computer usual these days), bought at the begining of 2012 and I can run all MAX (except shadow blur) and HDR on, at the begining of the beta, performance issues was a problem, but not now.
Proof of this is the community in which I'm helping with organization. Three championships, and one more will be opened next week because rF2, is having an incredible acceptance, after previous championships we have organized without problems (with more than 20 drivers in all races, sometimes 26, except single events where we was 12-20 drivers).
I think FSR need to test and know how rF2 works, because something is wrong with server, I don't know, but the issues I've seen over the Winter Series, I had not seen before, perhaps only in early versions of the game. And one more fact ... we have been working with up to 4 active servers, and running all perfectly normal.
The
proof here (This is the channel that I'm currently working), may seem that I'm doing spam, if so determined, somebody edit the post, or I edit by myself. Here you can see highlights with starts with more than 20 drivers, some accidents, overtakings, very close battles, and no lag issues or physics bugs. Also we have broadcastings of whole races (soon to be many more), but quality is somewhat lower because until now our cameraman didn't get correct settings. Despite of that boradcast are more credible than a montage, as they show the whole race without cuts or edits.
PS: I would like to see races like these in FSR with rF2, and better, would be great! I plan to come to try my luck at some point, when I have some more free time to train to a decent level.
