Green Tracks Whenever I read about some crazy lap time in a simulator (like 2:13 on SPA with a C7R on Assetto Corsa, 5 seconds faster than the real world record), people usually say the reason for that is because pretend drivers don't experience the fear of wrecking their car, and because the track surface is not green, the grip level is on maximum. While I can agree about not being afraid, I must ask: do "green tracks" really apply to most tracks in real life? I can't imagine a track like SPA, which is always being driven, lacking grip because of lack of rubber. Lap times Now a very controversial topic. Lap times. I, for one, don't believe that there's such "fear" of wrecking your car in real life, for a few reasons. Once you start doing anything new (e.g. riding a bike), there is a "fear" that you might push the limits too far, but once you gather enough experience, that act becomes a ride in the park. When I restarted biking in 2013, I didn't push my bike to it's limits exactly because I didn't know them and I didn't remember the general limits of a bike from when I used to ride them several years ago. But after several hundred miles ridden and doing the same stretch of road several times, I was able to push it to the limits: the road was bumpy and curvy, there were cars and trucks flying beside me; but still, I wasn't afraid to become a shooting nail (in shape) and do 60-70 Km/h while going downhill on the same road. I know the limits of the bike, I know the risks of going the speed I was going, but still there was no fear at all. Instead, all I felt was joy. And don't get me wrong, an accident with a bike at such speeds is way deadlier than if I was on a GT3 car doing Eau Rouge flat out. There's nothing protecting my body except a cheap plastic helmet that wasn't designed for great impacts. If someone should be afraid, it should be me, not a pilot with fireproof vests, a bulletproof helmet, a caged car with a seat belt, track marshals and tyre barriers along the track. With that in mind, I'm positive that a driver can know the car/track limits and do corners the same speed a racing simulation driver can. At least Schumacher says so So now to my questions. 1) If the track conditions are the same, shouldn't all cars in a specific class have similar lap times? Even if we still consider fear to be a factor in real life, it's not present in a racing simulator, so there shouldn't be a reason for one GT3 car do 2:19 while another does 2:15. This time difference isn't something I was able to observe in the real world, usually the top drivers have very close lap times while driving in different cars of the same class. The problem is, for an average sim driver who dedicates similar driving time for a few cars, shouldn't he achieve similar lap times instead of achieving huge gaps between each car? 2) Why is there so much difference between a specific car in different simulators, between the same car on the same simulator, and between simulated cars and real life cars? For example, in the C7R/Assetto Corsa I can do 2:16 on SPA on varying track temperatures, while with the URD C7R for rFactor 2 I can only do 2:20, it seems there's just not enough grip to go any further. How to know who's right and who's wrong? Considering it's the same car, if the data inputted is right for both then both lap times should be roughly the same, even if the setups differ a little, right? Continuing with this example, it confuses me even more when I consider a few factors. For example, a real life Ferrari 458 GT3 did 2:16:6 on SPA. This indicates that the ApexModding GT3 458 time is comparable to real life since I can do 2:16:7 after a few dozen laps of practice (started with a green track). That also indicates that my 2:16 with the C7R/AC is not far from reality. However, it really bothers me that someone can do 2:13 with the C7R/AC with a track temperature of 0ºC. There's something there which doesn't add up. Not only that, but it seems usual RL qualifying laps for SPA/GT3 is around 2:18, and race laps around 2:19/2:20. Now THAT I can see happening, but then several conflicts appear with the simulation world: while some rFactor 2 GT3 mods have a limit around that lap time (2:18 to 2:20), others don't. I was able to achieve 2:16:4 with a 997, a car from the same team who did the 458 which has realistic times compared to real life; and 2:16:7 with their C6R (it's a GT3 pack).... but with the C6R from EnduRacers I can't get bellow 2:18 now matter how hard I try it, and with the C7R from URD I can't get bellow 2:20, usually staying in the 2:24 range. What is happening? Did the guy in the video (Ferrari) find himself on a very special condition (track temperature, rubber)? If so, why am I able to replicate ~2:16 with the same and similar cars while on a 9ºC green track? And HOW would 2:13 on a 0ºC track be even possible to achieve in a simulator? Considering drivers don't experience fear, why don't we see more 2:13 lap times? Instead, most qualifying revolves around the high 2:17's and low 2:21's. How to judge which car is the most realistic? The ones that do 2:16 - 9ºC - green, or the ones who do 2:20 on the very same track conditions? And what about the 2:13 - 0ºC? AAAARGH 3) According to your knowledge, which is the best mod for Assetto Corsa or rFactor 2, in regards to the quantity and fidelity of data put into it? Cheers!
