Hi, in an effort to make my AI mod work with the game after patch #2, I did some extensive testing on the cars performances. With some interesting results. Track/mode: Melbourne GP Mode short weekend all sims on realistic rules Same setup for all cars - I know that some cars might "like" the setup more or less, but I needed fixed conditions. Setup: Wings - 3/3 Brakes - 50/50/normal pressure ARB - 2/10 Ride Height - 2/2 Springs - 6/5 Gearbox - 7th gear at 331 kph (on KERS-cars, same setting for backmarkers) Fuel - fastest mix. 5 laps fuel load Camber - -3.3/-0.9 Toe - each 1 "step" right from the middle Now the interesting part, LAPTIMES: (Yes, with full TC and ABS, but manual gears, I don't own a wheel ...) McLaren - 1:20,8 RedBull - 1:20,9 Ferrari - 1:21,1 Sauber - 1:21,6 (theor. best of 1:21,3 w/o invalid laps) - What the?!?!?! Mercedes - 1:21,9 Renault - 1:22,4 Force India - 1:23,0 Williams - 1:23,0 Toro Rosso - 1:23,1 Virgin - 1:25,0 Lotus - 1:25,1 didn't test HRT as I assume it to be level with lotus and virgin The Sauber is really a "duck out of the row". Seemed while driving, that it has much too much cornering performance, as it felt almost like the ferrari. So the players cars SEEM to be sorted "tier-wise": Tier 1: RedBull, McLaren, Ferrari, Sauber Tier 2: Mercedes Tier 3: Renault Tier 4: Force India, Toro Rosso, Williams Tier 5: Lotus, Virgin, HRT I count the Sauber as tier 1 as it is simply closer to tier 1 than tier 2. apart from the sauber it seems fine, sauber should (imo) be level with the renault ... AI cars are sorted a little differently: (taken from original database) Tier 1: Redbull, McLaren, Ferrari Tier 2: Mercedes, Renault Tier 3: Toro Rosso, Sauber Tier 4: Force India, Williams Tier 5: Lotus, Virgin, HRT So it comes at no surprise, that people report about teammates getting stronger over the season change, especially if you take into account, that the gap between the tiers is different for the player and the AI cars. Problem for my mod is though, that I cannot fix the sauber bug. Workaround is obvious: don't drive the sauber As AI cars they drive as one would expect them to. The main reason why I post all this, is if you guys can confirm that I tested everything on a blank savegame, so no tier promotions. Would be nice to get some feedback. /edit: The hacking order I would LIKE to see is this one: T1: RB, McL, Ferrari T2: MGP T3: TR, FI, Renault, Sauber T4: Williams T5: Lotus, Virgin, HRT What do you think?
