Grass. I just don't understand it. Help.

And to McRipHelmet, hopefully I'll get some time to play around later. This isn't just a Me opinion. I actually convinced my friend to buy it, and he has the same opinion. The game is nice, as i said earlier I think I actually prefer it to AC overall, but this is the one thing where I think "that ain't right".

 

I'll just quote this post I made in a separate "AMS 2 grass is too slippery" thread awhile back. It's a breakdown of Pato O'wards spin at Barber.

TLDR; while I do think there is some truth to AMS 2's grass being less forgiving than IRL, I still find that you have to use similar driving techniques inorder to get out of the grass in both real life and AMS 2.

 

The thing I note from Roar is that he says he believes you when he obviously doesn't. I don't understand why he does that but I won't do that. I won't lie to you to appease you. That's not what being polite is.

Someone saying you're wrong isn't impolite. It's not impolite to disagree with someone. But my initial post suggested to post a video. It didn't say you were wrong at all. You are wrong though. I think by now there's not much chance of you posting anything that would suggest your initial post is reporting a bug. You can convince me I'm wrong but you won't persuade me.

The next thing I note about Roar is - and it's relevant given the first reply you had - he managed, without using a safety net or any stooges in the audience, to post about 7 videos showing the problem doesn't exist.

Which, of course, you ignored and your next post still says the opposite. Without any effort on your part to demonstrate the bug you believe the game has nor give any useful details about what car or track or anything. If your friend has the game and believes it, ask him to post the details.

As for sarcasm about donuts you say things that are just not true. Not about this game. About real life. If there's a cult that believes physics IRL isn't buggy then, yeah, I'd probably join that one. And real life has cars that spin at low speed from throttle input.

The game is full of bugs - there's a huge thread full of them - there's no problem with the game having a bug.

 

Im going to assume if youre making 700hp its a turbo so little hp and torque out of boost Easy to drive. I can only say my 500hp K5 Blazer with 35 inch tires and 4.56 gears will spin the tires on grass if i barely touch the gas. But i built the motor for torque not hp at 7000rpm. I actually dont think the grass in AMS2 is far off.

 

Yeah, its 3L so not gutless down low, but it's not a big torque monster off boost. I'll experiment more later and certainly try to keep an open mind, but from what I've seen playing AC a lot, plus my real life experiences, I'd have to say it's AMS2 that is too slippery rather than AC and my own memory of real life driving on grass being too grippy.

For one last time i do want to add that I think I prefer AMS2 overall vs AC, this isn't an attack post, but in this one area it doesn't feel right to me.

 

To be clear, and trying not to end up being epistemological: I'm simply giving the benefit of the doubt until any data supporting the claim has been shown.

I also note that you described it as a bug, while MacAttack hasn't - to me it's more a question of whether or not a friction variable in the physics engine needs further tuning to better represent reality.

On a related note, now that the two threads have been merged I'll address a broader topic:

When comparing driving on grass behavior in AMS2 with other driving sims, keep in mind that Niels Heusinkveld has showed that AMS1, AMS2, rFactor 2 (and likely also LMU) have a different throttle response than most other driving sims, where the other sims need much more throttle input in order to produce the same torque. So if you for example compare how easy it is to spin on grass in AMS2 with 10% throttle compared with Assetto Corsa with the same amount of throttle, a much higher throttle% is needed in Assetto Corsa for the comparison to be fair.
Consequentially, it's easy to come from other sims with the different throttle response and notice how much less throttle is needed to spin on grass in AMS2, but keep in mind that the the throttle response has been designed to work like that.

 

The throttle is one of the things i noticed immediately when i started playing AMS2. It worked and felt like id expect driving a real car. Linear is probably the wrong word but it feels much closer to reality for me.

 

Bringing this thread back to life, does anyone feel traction on grass with V1.6 has taken a massive step back? The final version of V1.5 actually had very realistic traction level on grass. On the current version of V1.6, if you find yourself with slick tires on grass, it's like driving on ice. Almost no traction and cars just spin themselves with very little throttle.

 

I think it has improved since the update?

 

Definitely not worse than before. And it's definitely not like drving on ice. Take a car at Brands Hatch and miss the turning-in point at Hawthorn Bend or Sheene's. You will see that you can perfectly fine use the grass to get back on track again. It happened to me so often.

In this video I was driving the Porsche Group C at Brands Hatch in v1.6. Watch 04:34 or 07:13:

 

I have to say that in the rain ams2 it slips a lot, is it realistic? and I always wonder if the effect of being on an ice rink when you leave the track (grass) is intentional?

 

Check out videos from real races. It appears to be largely realistic compared to real life, though not what you get in most other race sims.

Combine the two, soaking wet grass, and you will see that a car with slicks may not even be able to get off the grass and back on the track if there is even the slightest incline or a curb to traverse.

 

Ever seen a real race car drive well on grass in slicks ?

 

To add to what Marc mentioned, There’s a classic one, check Prost slipping on the wet grass on formation lap in Imola 1991, he didn’t have traction to get back to track with his Ferrari and had to retire before race even started . He probably felt in a ice rink.

 

I remember back when i was young and worked at a marina. We had a f250 that used to get stuck in the park if the grass was even a little bit wet and that had 4wd. If you saw the hill youd be like theres no way it got stuck but it would. Just sit and spin the tires.

 

And tell me, is the exit from dry grass implemented properly in the game? Because the car slides quite a lot too

 

Shouldn't it? Again, show some videos or evidence of cars on hot slick tires getting traction on grass as if they were using normal temperature treaded road tires.

I will say that in real life, the surface beside a track varies a lot, from manicured lawn to hard-packed dirt under a sprinkling of grass or weeds. The traction will vary a lot. But AMS 2 isn't a grass simulator, so we may only get one (or a very few) off-track level of friction.

The purpose of grass beside a track is to make sure you know if you go off the track, you are in serious trouble. Same with sand or gravel. This used to be the norm--that if you left the track or hit a (giant, back then) curb, you could assume you were at the back of the pack at best and out of the race at worst. Modern racing is all about keeping as many cars going to the end of the race as possible for commercial purposes.

 

I did a Verstappen overtake yesterday at Sebring - Pretty much my whole car was on the grass but i did not crash or spin

 

You can successfully drive with two wheels on the grass and two on the tarmac, in a car with down force, and make a pass on a straight, in AMS 2 just like in real life. I think the comments here are about spinning off onto the grass and what happens afterward. Or, how easily you can spin off when the track is not straight.
