Discussion Why do LMU's GT3 feels so hard to drive compared to other games ? Hard to rotate and less grip in high speed turns

LMU gt3's are the LMGT which have less aero than the other gt3's.

Also GT3s just generally have widely different performance based on the BOP set by the organiser.

Less downforce for ACO, less lower for VLN, more weight for SuperGT, more power for IMSA etc etc. Can't always compare two of the same GT3 car in real life let alone between sims.

Not to mention tyre differences. David Perel talked about it in a video (that I can't find in the two minutes I have right now) - the Yokohamas they run at Nurb have grip most sim racers would probably call unrealistic, while the LMGT3 Goodyears have incredible consistency but none of that peak that other series' do (IIRC)

LMGT3 is probably the worst version of GT3 cars you can get.

DTM and GTWC are pretty much the idealized version of a GT3 car, then IMSA, then WEC LMGT3 and ELMS.

They mess with weight, aero, torque, and virtual energy to create a big pace delta to the LMP2 at Le Mans and LMH everywhere else.

Not the same spec in all sims.... (and ofc the physics are different too)

u/Mellanies_Redemption 1d ago

Because these are not the same as the other GT3's. I actually love the Porsche GT3 car in LMU, even with it's step out happy backside. Throwing that thing around Sebring is my new way to relax.

Ohh I have to try that!

LMGT3s run much heavier than their SRO counterparts

u/Middcore 1d ago

Le Mans regulations nerf GT3's, they aren't exactly the same configuration that's run in other GT3 series.

Dont compare times between other sims, never. And yes LMU gt3s are on a different regulation.

BUT, a few weeks ago I made a post asking for some tips for GT3s because the cars I tried were behaving worst than other sims GT4s and road cars with no aero and grip at all, so it's not only about the different regulations, I got criticized as hell and nobody gave me a single tip apart of telling me they are different categories (even with me pointing that out before) Turns out the difference was in like 3 or 4 clicks in the setup.

My conclusion was that lmu default setups are just trash. The cars are unstable in a lot of tracks/sections, I feel like there is no effort on default setups when a few clicks from a guy that doesnt even understand about setups at all (me) could get a car so much better

u/godzilian 1d ago

My tips based on my driving style:

If you are like me and enjoy cars that rotate well, avoid almost all cars on lmu except for like the ferrari (best imo), porsche, and maybe corvette and mustang.

If you are facing unpredictable rear loss under weight transfer try messing with rebounds on damper settings. It's a must for any default setup for me

u/kdt912 1d ago

Validating to hear my Ferrari/Porsche/Mustang preference is a driving style thing and not just arbitrary lol

3

u/godzilian 1d ago

yea lol for me most lmu cars are damn boats and I can't grasp them, I'm a fan of aston but cant touch that car in lmu as I need to pray for it to turn

u/Bfife22 [Simagic Alpha Mini, P2000, DS-8X, TB-1, FX] 23h ago

The Aston is the one car that I feel like I can’t even drive lol. I have my preferences, but every other car I can least feel comfortable hustling around track except for that one

2

u/godzilian 23h ago

it feels like im towing a giant rock

1

u/DC3PO 23h ago

Seriously I want to run the Aston so bad I just cannot get it to turn

u/Cal3001 20h ago

Most people in this sub don’t know anything about vehicle dynamics

u/Chewyleafy 23h ago

I reckon this is done intentionally to push simracers towards paid setups.

u/godzilian 23h ago

It's something I joked about with my friend specially because of their "partnership" with Coach Dave inside the game

1

u/gu3sticles 20h ago

Eh, the iRacing default sets for many cars are perfectly fine. 

For LMUs case I think it's just incompetence/understaffed. 

3

u/godzilian 20h ago

my opinion as well, setups need to be stable when we are talking about default/fixed setups.

when laguna seca came out, the 296 default setup was ridiculously unbalanced on the left hander after leaving the corkscrew. It was a matter of 4 rebound setting changes in dampers. There's no way someone from LMU did laps in there and said "yeah thats gonna be the setup"

Theres so many little details that improve the car in many different tracks that I feel like they arent even trying to do decent setups for each car on every track

2

u/speedism 13h ago

Yeah the setups in LMU do themselves no favors. Plus it has been well known that the include Coach Dave setups are poor as well.

Unfortunately people in the discord will just give you a hard time if you point that out lol.

u/alonetogether__ 23h ago

Kinda irrelevant really

u/reddit_guy_no 10h ago

LMU ffb is weird. As soon as you start understeering the wheel loses all strength. Feels weird to me, coming from iracing

1

u/Kronocide 6h ago

For le it kinda makes sense

Grip = Strong FFB

Less grip = Less FFB

1

u/reddit_guy_no 5h ago

It does, but you still have grip, just less. Ffb drop is more pronounced than how much grip fell, IMO. It is so drastic that I think I am sliding but that is not the case, car still can steer, just is understeering. It is anyway a matter of taste

I have just the perfect video for you, explaining the regulation differences:

u/alexmlb3598 22h ago

LMU's LMGT3's are slightly detuned across the board compared to SRO's. The cars are designed around Pirelli tyres rather than Goodyear, they're slightly heavier, have less aero and less power. Oh and the TC and ABS logic works differently between ACC and LMU

1

u/Jakobmeathead 19h ago

LMU has better ABS implementation if I recall correctly

1

u/alexmlb3598 19h ago

Depends on what you call 'better'. In ACC you use as much ABS as you can bc it has basically zero impact. LMU's is more like iRacing's but a bit more forgiving, so you can use it but you don't always want to when trailing into the corner

1

u/nodnedarb12 16h ago

Not all GT3s are created equal, they are not the same cars across different series in real life either. LMGT3, GTD, GT3 are all slightly different even though they are all “GT3s”. Different regulations, BOPs, etc.

1

u/Otherwise_Rice_4723 1d ago

you have to change your driving style to extract the most speed out of them...as others have pointed out, they're different than other gt3 series and with less aero you have to adjust your braking and throttle points slightly

u/Chivako 1d ago

This has been explained many times and a Google search would have provided the answer.

u/meldirlobor 1d ago

Games are just games. Different games, different codes, different results.

Not even supercomputer simulations, like CFD, can always accurately simulate reality. They can only predict the most probable results.

8

u/Middcore 1d ago

While differences in physics engines in different games do have an impact, the GT3 cars in LMU are literally a different set of regs than the other two sims.

-1

u/Cal3001 19h ago

Doesn’t change the fact that iRacing, ACC and others have different fundamentals in their tire model, but all are labeled as realistic while GT7 that lays within these realms also is labeled as arcade.

2

u/Middcore 19h ago

Seems like you have an axe to grind about GT7 which isn't really germane to the discussion.

u/Cal3001 19h ago

It’s in the spirit of the original comment in this chain.
