Just discovered this channel and am finding it immensely valuable. This level of technical detail gets me more engaged.

Good to see you uploading regularly again, always learn something from your insights!

technical things made simple, always great watching your videos!

Very interesting and complete. I was really wondering why the TC was so broken on some cars. The torque/throttle problem is now clearly understandable. Kunos must do something here. It's probably great to have fun. But not realistic at all. As for the tires, we all agree that there is too much grip in the slicks in the wet. Even if the behavior on the wet tires is quite good in my opinion, there is also a little too much grip.

And another lecture with professor Nils. My brain gains are massive in recent weeks💪

love your videos man, i dont even play ACC anymore but I sure watch every video you put out, always so interesting

I really admire these videos Nils. Well thought out explanations, with possible cause and effects explained. I see these as guides for the player base, but also a nudge to Kunos. For me this is how you give constructive criticism based on data and knowledge. Thank you.

I loved the no TC Servers on the old Assetto Corsa on Laguna Seca. Once in the flow, it was an amazing drive :D

yeah really nice vid and analysis and all but can we all just appreciate him putting a full on falken drift show! man got moves :D In all actuality, amazing video, thank you!

This was outstanding! I have just subscribed.

Great information. Thank you

I've tested this in automobilista2 after this video and found some interesting behavior and implications. TC is absolutely needed with that kind of accelerator profiles. And the fun part starts here. With the bad/slow TC you lose so much that in some corners once the grip is restored you need to drop from 5th to 3rd end if you don't the engine turns off. And it's not like you lose speed so you gear down. Not at all. You go through the corner you know it's kinda flat but not always you catch a small slide and the engine fucking dies mid corner. Barcelona is my go to if you want to experience the horror. Try amg tc 6-7. That got me thinking what if TC was great and was engaging after the peak grip and turn off fast enough. That would mean you just want to ride the TC all the time to be sure you max the grip all the time. So the pedal to the metal all time and you're micro sliding all the time. Exactly the way ams2 drives on lower tc. So the end result is the opposite less skill and accelerator modulation. And when I say less skill I mean I am 2 sec faster in ams compared to acc. On the updated Spa which has less track and tighter limits in ams. I know it's apples and oranges but the difference is like it's watermelons and potatoes instead. Either way bad tc settings are catastrophic engine cutoffs. Good tc it's a no skill micro slide fest to go fast. Both are way worse outcomes for the average driver. Oh yeah shifting gets very important you now lose way more time every ms you delay the shift. Getting faster exit then usual changes the shift timing out of the corner you miss it a bit and actually lose time which is hilarious :D Overall I'm sure ams didn't help to make a great judgment here but there are downsides to this. Maybe devs are not wrong keeping it the old way.

Again, great video, up until now most ACC simracers kept just saying "Oh, I drive 0 TC because... it works!"... now there's a proper explanation for why and how this works... and now I know why I enjoy other sims so much more - sorry to say that, but for me it's unfortunately true. I still like ACC, it's very affordable, in an overall great state, stunning visuals yet you don't need a super beefy PC to run it smoothly. I don't wanna say "ACC is a well polished mass product", that's not true, it's still a hardcore sim not suited for everyone out there who wants to race in a virtual environment. But honestly I think there are better options... that's just me. I would love to see/hear comparisons to other simulation games (yeah, I wrote GAME!!! ) just to see how such mechanics are handled on other sims... although I assume this would require a tremendous effort in terms of time. Great stuff, Nils!👍

Thank you Mr. Nils!! Now i can gain the 10 seconds i lose pro lap at Spa, i just turn tc off and i will be able to do 2.18s!! Really positively impressed how deep your analysis go.

I would really love to see the "improved" throttle model be implemented in ACC

Jumped into ACC recently and just went with my normal AC settings 0TC 0-1ABS. ACC's rating system claimed I was losing control when driving on slip angle and I had to turn on both TC and ABS, to conform to the seemingly subdued driving style ACC has wanted from me.

another excellent video

A bit sad, that it seems there is less oversight with the compliance to deliver a realistic expierence for ACC. TC 0 is never happening in any GT3 car in real life. Thanks a lot for your in-depth analystics.

Best Man, Danke

Well that explains why Suzuka felt like Richard Burns rally.

I think the reason the steering is more vague on center in 1.9 has more to do with side wall flex increasing a lot for 1.9. The grip vs slip ratio example graph gives an idea of how peak grip is achieved once the tires reach their steady state. But the tire sidewalls flex a lot in 1.9, so it takes a lot of time during turn in for the tires to reach that steady state. EDIT: Apparently side wall flex is not higher now, although I believe sidewall flex behavior has changed from 1.8 to 1.9. I believe if you make a graph displaying steering angle / lateral acceleration, you will find that graph to be more steady in 1.8 than 1.9. you may need to do (steering angle)^2/lateral acceleration to avoid noise when steering is nearly straight. Might also be worth gating to a minimum steer angle. The purpose is not the output values but to see the relationship from 1.8 to 1.9.

I remember thinking to myself "how can they get so many complex things right and this one simple thing (throttle model) so wrong, when I started driving IRL cars. And it took millions of years for someone to mention it in Heusinkveld. I also thought that the torque curve is too peak-y/not linear enough in many games, for road cars, but maybe it's just perception. Anyway, if I see you playing that WRC Whatever I'm walking to Germany and applying torque to your neck

Every time i move from the standard setup even slightly, including just turning down TC1/2 i am instantly SO ass.. even with practice when i get to where i feel close to limit im slower than with standard. Im pretty new to sim racing but still its discouraging and frustrating 😂 need one of those coaching sessions or somethin i guess

Combine the throttle map with the weird steer ratio and you have the reason it is so easy to control those exit high slip angle and gain laptime this way. If Kunos was to either change the grip fall off past peak torque, the torque maps or the steer ratio, meta would most likely be very different again.

Could I experiment with this concept by simply lowering TC a couple steps down, or must I turn TC completely OFF to enable this effect?....I enjoyed today's class! thanks!

Great video. I learned a lot. Thanks.

Hello Nils, do you actually have access to the betas of AMS2. There was in the meantime yes diligently further developed and there is on end month another big tire update out. How do you like this new development?

Interesting video Nils. Are you in contact with Kunos to maybe tweak these things for the next big patch?

Thx...

Could we please have a one off payment option for Popometer? I really hate subscriptions, it makes looking after banking details so bloomin time consuming!

Sehr sehr schlau 👍

Tnx now I know why I hate slow speed corners in AMS2 so much

so TC0 and send it on corner exit. Message recieved. Crash almost certantly coming up :)

Amazing video. So, if we had a realistic throttle model, TC2 would be actually useful, no? Also, are you planning to do a video on ABS and if its realistic or not? Some real drivers say that it isnt because of the lack of trailbraking or brake modulation at all. Could it be because of how much grip the tires have, wich means you dont need to trailbrake a lot to rotate the car? Or could it be, that the suspension model it has right now is almost the same as before (1.8), wich gave a lot of mechanical grip to compensate for the lack of slip angle. And because it wasnt changed, it gives more grip to the tires..

Regarding the torque output and throttle application. Using Map 1 or 2 in the Lambo EVO2 increases the torque output drastically with small throttle inputs. So in this case you could use those maps to counter that issue or for other cars use the pedal software to adjust the output of a specific throttle pressure.

Liked: check. Subscribed: check. Comment for the Algorithm: check. Face palm for not subscribing sooner: double check.

i always felt more comfortable with driving with TC on even if its just TC2 or 3 instead of TC off, ACC threw me off in patch 1.9 so much that i didnt enjoy it anymore so i stopped playing it, even though i still think its a good sim IF Kunos would do something good for their game, i did have lots of fun in 1.7 and at start of 1.9 but not anymore sadly

Mr. Nils, as a smart guy i would like to ask your opinion this spreading 0 compression max rebound damper thing. Is this again about reaching minimum ride height? Is it only me who find it ridiculous as a stupid engineer trying to stand on earth with both legs, or it is actually ridiculous?

Try tc off on bentley and see if it works 😂 audi has the tc0 bug anyway. Little bit kunos fault that some cars can use tc0 and some needs high tc

I don't think the complaint about Niels' model applies. Sure, this model isn't correct for classic cars with physical throttle linkages. But modern cars with electronic throttle bodies use a very similar mapping to the one that is used in sims.

More pdfssss

Is this game still popular?

People in the real life Spa 24h were driving multiple laps on slicks even when it started raining... but otherwise interesting analysis.

Massively triggered - as someone who was a long term aston enjoyer and is now struggling to run with low TC never mind no TC :D

I consider tc a band aid for poor setup, and the less tc the better the setup is. And proper brake bias is a better form of abs, and I think using good brake bias, and as little abs as possible helps. Regular ac used to benefit from no tc in some of the gt cars for me, years ago

We already have the FOV police who berate people who don't abide by their less than accurate FOV regulations and the "no-TC" police who look down on anyone who has TC switched on in the F1 games. Of course, we all know that F1 cars do not have TC, so driving with it switched on is not an authentic experience.. But GT3 cars have TC, so turning it off is also not an authentic experience. In fact, turning it off, the going out and setting a alien-like lap time is the very definition of an "exploit". So now we need a new police force to insult guys who are taking advantage of the exploit and setting crazy-fast lap times.

isn't that just a exploit to be fixed ?

Hallo Nils leider etwas verspätet dein Video genossen. Bedeutet es das ein lineares Gaspedal schlechter ist als ein Progressives Gaspedal wenn man TC Off fährt. Gruss Micha

Seeing all these videos and how the dlc feels unfinished makes me think that they are in the process of dropping support and simply focusing on AC2 to avoid having to deal with all those little and small problems in and with ACC

It is so annoying since 1.9 i have no fun and no Feeling/Trust in the GT3s Cars since then. I dont and wont understand the weird Drift Angle. The Car always has weird feeling of Grip like it drives on Ice. I go on the Power and the Car is like ''YEAH LETS MAKE THIS RACE CAR TO A DRIFT CAR AND SCORE SOME COMBO POINTS DRIFITING THE NEXT FEW CORNERS LIKE I DONT HAVE TONS OF DOWNFORCE AND SLICK TIRES'' It is just fckn annoying. I pretty much dont touch the GT3 Cars since 1.9 -The Grip is weird/ not there in Situations where it should be -The Car always rotates way too much and starts to drift and loses even more Grip -Downforce and Slick Tires and basically non existent in 1.9 For me and A LOT of other Guys (i read a lot of Comments aswell in the Nordschleife Trailer from ACC, where a lot of People complain about the Game and about the same Issues) the 1.9 Update especially on GT3s feel completely wrong. Like there are huge Mistakes made. And i still wonder why you Aliens dont adress this more. Because would it fix those Problems if they make the TC usable/mandatory again? Or the Throttel Inputs with its Torque correctly and such? I had until 1.9 like i guess 3000h of driving with the AMG GT3 (old and new one combined) And i do had Problems to adapt to the Evo, but i got pretty confident and fast with it over Time and at the End i had no Problems. Now, after 3000h of Driving Time with the Car it feels not like an AMG anymore. It feels completely wrong and foreign. The Steering got way more sensitive. Almost like the Porsche where you just needed to steer like 1 Degree and the Car immediately was steering like a Maniac in that Direction. But the Cars Balance and the Things i said above are now a big Problem. I really dont get why People actually find this 1.9 Update (apart from those Problems you mentioned) enjoyable AND acceptable. For me it is not! I would rather have 1.8 back. There i knew what the Cars were doing even with the buggy Dampers and no Chance to go over specific Bumps/ Curbs without dying. In 1.8 the Drift Mode wasnt enabled and you actually could drive around a Track and Corner without losing Grip or start to Drift every fckn time...Because Grip, Slick Tires and Downforce actually existed there.. In my humble non Alien Opinion the Slip-/ DRIFTangle is way too much or at least something else is wrong like the Tires cannot make it feel like you actually have a grippy Car. I drove Waktins Glen yesterday on LFM Practice Server and i was laughing so hard because i just tested the Audi Evo2 and the Aston and just wanted to have a chill little ''Track Day'' so just driving around and enjoying the Track/ Car.... I lost both Cars in weird Situations where i never lost them. You go through a Corner and either have no Grip at all or you do but when you touch the Throttle the Car is in Tokyo Drift Mode and for that Moment they magically changed the Slicks to Ice Tires and quickly dismount the Wing.... so the Car was drifting like a Maniac out of the Corners and into the Wall. One Thing i noticed is that when this happens and i want to counter steer and take back control of the Car i dont need to do it on my own. When i have my Hands on my Wheel and wanted to catch the Car in those Situations it gets most of the Times worse. BUT when i take away my Hands and let the Car do its Thing it calms down after some ADHD Attack and it actually drives straight again... Well but that i can only do when i am on my own :D Because in a Race i wouldnt take my Hands off my Wheel just to make sure the Car gets stable again because i am not able to control where the Car is going .... Another Problem is with my Fanatec Wheel Base... since 1.9 the Game seems to have more FFB.. which is fine ... but to not Clip the entire Time i have to reduce my FFB of the Wheel so much i have even less FFB than 1.8 and pretty much no FFB anymore because it became so light ... For Example going through Eau Rouge .. with GT3 Car and with GT4 Cars my FFB is clipping the entire Time ... going up the Hill (Turn 2) in Watkins Glen aswell... The FFB Bar is red all the Time and i have no Feeling over the Car... Yet the FFB is set lighter than ever before... when i go down even more i can drive with a Game Pad ;) WTF!? All in all 1.9 is a shame for GT3s in the Game
