If you are like me and originally got lured to R3E because you were nerved by the inapt AI in Assetto Corsa, make sure you check out the new update 1.2.1, which not only comes with Zandvoort track and five new cars, but with a whole truckload of tunings, repairs and features. Amongst all that is a massive improvement of the AI, which now can really overtake and provide you with acceptable race event experiences. It still is not as vivid and good as for example R3E in this regard, but it is, by all means, solid. Physics and FFB have been tuned as well, physics are even more superior now, I would say, while most people agree that FFB is even more subtle now, almost benchmark in some people's opinion. To me, the FFB still is too weak in general, but I have to change my former view and admit that it indeed was tuned to make more subtle effects noticable now. The new cars are wonderful. All of them. I love them all, more than the 10 cars in the dreampack. The Zandvoort track advertises itself for comparison to its R3E pendant, since it is not laserscanned, but done with GPS and some other clever techniques. By looks of the trackside,m the R3E track as usual looks more vibrant, colourful, more alive, while the AC tracks has less object details and uses the usual pastel colour palette, giving the whole place a very different atmosphere, somewhat abandoned, forsaken, lonely. The driving on both tracks is great, however, though different. The R3E track has some steeper camber here and there, and with that might be closer to the real thing, according to some feedback in the AC forum where people compared to the real track which they know from own driving experience. However, the R3E track is relatively smooth, the AC track is more bumpy and probably in that regard is more realistic. The AC version reassures me in my opinion that laserscanning is not absolutely necessary for creating good and enjoyable tracks: I love both the AC and the R3E version. All R3E tracks are not laserscanned, but I rate them amongst the best tracks I have ever driven and seen in the past 25 years - and the same I say about the very differently created AC tracks. So, laserscanning is nice if you get it, and if not, the sky nevertheless is not falling. Further improvements on the MP side, many people I read in their forum saying that for them all what they wanted for MP now is there. Considering what a notoriously nagging group multiplayers are LOL, this really says something. In the AI department, R3E still holds the lead, but the lead has become much smaller. Regarding physics, Assetto Corsa is the leader, and it has developed that lead further. Racing events against the AI in AC now makes sense, especially with slower car classes with more stable attitude. I currently would recommend to be careful with BMW 235i's and the Lotus Formulas, which the AI is not able to control with the standard it shows with most other cars now. I tested extensively yesterday and on almost all Kunos default tracks - all turns 1 and 1 in first laps were successfully negotiated by the AI, no major incidents, and the overwhelming majority of situations were passed by the AI without even minor touches. Collision physics also have been repaired. I would compare them now to what you have as standards when establishing car body contacts in DTM-92 cars in R3E. I found all incidents when I managed to spin off - to be triggered by my own fault, hitting too fast or doing something stupid in front of the AI so abruptly that it simply had not time to react while obeying physics. Plenty of car body bumping and paint scratching between them and me - and we both running on. Collisions really compare much to R3E now. Very good.
