AMS 2 | Build Update Now Available

Reiza Studios have today deployed a sizeable new update for Automobilista 2 - adding many fixes and improvements to the simulation following on from the major release of earlier this month.
  • Significant Spa update.
  • New tyre physics.
  • Improved AI.

Not content with a massive build release to see in the New Year, Reiza Studios have again taken a chunk out of your internet download allowance with the release of build earlier today - adding yet further refinements to their current generation racing title.

Considered by the studio as a 'complementary' release, but seen by almost everyone else as a major build update, V1.1.0.4 deployed to the simulation earlier today - and with it comes a wide range of satisfying sounding improvements to a simulation that continues to make great strides from what was a shaky start to development.

Update Notes

Automobilista 2 has been updated to v1.1.0.4 - this is a substantive complementary update to the release from two weeks ago, the highlights being several improvements & corrections for Spa, new tire & driveline physics developments along with some new AI logic that should greatly improve their skill dodging traffic in multiclass races.

Please note that while there is no need to delete your Automobilista 2 settings folder in this update, several cars require a setup reset to default to receive some of their latest adjustments as marked in the changelog below.

  • Fixed inverted slow / fast damper rates in Porsche Cup cars (requires setup reset)
  • Fixed asymetrical right front ride height setting in Porsche Cayman Clubsport (requires setup reset)

  • Added new overtaking logic - AI cars now evaluate speed of cars further ahead to dodge slow traffic more efficiently
  • Fixed bug causing AI simulated times to fluctuate widely
  • fixed issue where AIs would brake without reason on pit entry or exit
  • Further general AI performance callibration for throttle & brake application, tire rolling resistance & drivetrain losses (to better match player straightline speed), launch speed (slow starts still remain an issue with Group A & Procar)
  • Increased AI speed on wet tracks while running slicks
  • Slightly increased AI aggression scalars per vehicle
  • Further reduced AI jerkiness in lateral movement
  • Reduced AI brake distance offsets
  • Fine tuned AI brake performance
  • Update AI fuel load logic for practice sessions (now uses same as quali - further customizations of fuel levels per car will follow in subsequent builds)
  • Slightly reduced AI quali performance & improvedp practice performance (all cars)

  • Minor sound loop corrections on transmission whine samples for GT3R and M6 GT3, Sprint race and Super v8 samples.

  • Updated weather probability ratios (a bit less rain generally)
  • Spa: Extensive art & performance pass; added night lighting, added more static objects around scene, more trackside objects; fixed some tree & treeline shadows, fixed holes in paddock area looking from Bruxelles; added new kart building and marshall huts, updated pit fence and other fences; updates to foliage and outside terrain/roads to match the 2020 look; reduced foliage around Blanchimont; Generated new AI paths (much better fast line); adjusted track cut runoff limits
  • Imola 1988: Fixed a few wall and terrain gaps; Minor AI grip increase
  • Goiania: Rebuild armco collisions in attempt to fix ireported ntermittent collisions
  • Curitiba: Further road mesh noise revisions
  • Curvelo: Reduced road mesh noise
  • Guapore: Reduced road mesh noise
  • Ibarra: Updated trackside cams for reverse layout

  • MetalMoro AJR: Fixed tail lights, external mirrors;
  • MetalMoro MRX: Adjusted RPM LED ranges for P3 variants
  • Further fine tuning of exhaust parameters (for cars producing less backfiring)
  • Further adjusted carbon visual brake glow range
  • Added new Metalmoro AJR liveries (including a new batch of community skins)

Falling in love with AMS 2 again and again!
Today I had a great race against AI Stock Car Nova Geracao @ Londrina Short and practicing/surviving McLaren GT3 @ Nordschleife.
Looking forward to next development, Reiza is on very goood way.

I have confidence that these guys (unlike how SMS abandoned PC2) will keep improving AMS2 until it's a classic like AMS1.

Still think AMS1 (depending on the car) has the absolute best physics/ffb combo of them all. But they'll match it eventually.

  • Disabled downshift autoblip for Mclaren F1 GTR, Porsche 911 GT1, MCR 2000; enabled for Metalmoro MRX P2,
I’m really curious what the reasoning is behind this change. I don’t really have a complaint about it. I just find it very odd that a simple yes/no on/off thing like this would get changed very shortly after cars are released (GT1s) or long after they’ve been released (MCR & MRX).

Anyone else having an issue with auto blip/lift on upshifts seem to have been disabled on all cars after this update? Downshifts seem to work fine still. Or is it just me?

Looks like a great update. However the driving on GT4 vehicles (in particular) appear worse (to me), almost spongy like. I wonder if anyone else is having similar issues?
Don't be too surprised. I think they are starting to dive into the guts of the drivetrain implementation in the madness engine and changing some of the fundamentals which will probably break some cars whilst fixing others as fundamentals change and they get around to tuning cars as a direct result. I don't know this for sure but only gather this from the public physics thread in the AMS 2 forum. It seems only the Beta backers are qualified enough to actually know what's going on behind the scenes so we only get crumbs of 3rd hand information, but if what is being suggested is true (that they recognise and are actively investigating some of the differential abnormalities with a view to change / fix them) then that is a positive step even if things get broken along the way.

Would be great to see some public statement backing up this premise, but at this stage, that's the inference as far as I can tell.

didn’t have a chance to try everything in the patch notes so will reserve any judgment for now but good first impression.
Interestingly, there was a second update 12.7 MB that popped up after calling it a night :O_o: (just minor patch i guess...)

Reiza is on a very good way with the game more and more. Circuit Spa-Franchorchamps is beautiful , for me the best version on the market , The coming of GT1 is great also , a lot of racing fun , Looking forward to the 14 km - 1970version of Spa. Thanks Reiza and go further on this way! :thumbsup:

Well I had plans for this morning, now plans have changed into some hours on AMS2.
Another great update, thank you Reiza :)

Just been trying stuff out, lost real life 4 hours easy as that.
Set the scene..
Custom detailed FFB from Reiza, weather from clear, cloudy, rain, clear. Time avancement up, all graphic settings on ultra.
Spa, vintage F1 gen 1. 7.1 headset, track IR5. No VR yet..
Started as the sun came up, just hot lapping, watched as the weather changed, then the rain, so twitchy in the wet!
As the afternoon came in, the clouds cleared to show a fabulous sunset, then into the dark.
Spa is awesome, the drive, for me was glorious.
AMS2 is fabulous.
