Automobilista 2 Custom Force Feedback - Overview & Recommendations

Thanks for your work, the files are awesome. Hopefully the Automobilista 2 release version doesn't screw things up with them.

 

@Karsten Hvidberg Thank you so much for your work on these files! Curious though: Why are you stepping away from them? I didn't think Reiza has made many changes to the FFB, or really plans to for the 1.0 release, but even if they do, I would think that only makes your expertise more valuable.

@NuScorpii Will you continue to develop the Heavy Messing series?

Thank you both for your work and contributions to the community.

 

Thanks Karsten. I think it is a shame you are stepping back, you've helped push what's possible with the FFB in AMS2 further and faster than anybody would reasonably expect. Some of your concepts I think will form the basis of most custom FFB files to come so I hope people will always give proper credit for those. The respect goes both ways. Some of the later enhancements you have made have been intriguing and can only be admired.

As you say we haven't always seen eye to eye but I agree that a lot of that is probably down to the communications format. I'm glad that we are in a better place at this point.

Thanks for the offer of using your concepts in PC2. However, it is hard to polish the turd that is PC2 FFB. Using the Fx_load to drive the road noise / texture is one idea that might work though, if so credit shall be there!

Best of luck in whatever you are turning your talents to next!

 

Thanks so much for all of you work man! You've done an amazing job to help take this sim to the very top in my opinion. Seriously man, my hat's off to you. Great job!

Just tried your final file... we need a "Drop the Mic" Emoji for this one. That's a heck of a way to make an exit my friend!

 

Thanks too to both of you, @Karsten Hvidberg and @NuScorpii! Your works truly transformed AMS2 handling since many previous builds. Now we hope you don't hang your hat too soon, @Karsten Hvidberg, we haven't seen v1.0 yet and who knows what it will entail . Nonetheless, as things are going, it's already amazing. Kudos bros!

 

Just tried 1.8 and it is superb. I can't see how Reiza could improve it. They should take inspiration from you.

 

Hi me again LOL. What is your wheel and in game settings as I'm finding this FFB quite heavy but overall very good. Thanks.

 

Csw 2.5 It's in my sig down there. 75 ish 40 50. Worked right out of the box for me, although i might reduce the lightness under acceleration as some corners feel a bit floaty.

 

Wow is it with Karstens file v1.8? Im on 60.45.50. Are you getting the oscillation turning the wheel in the pits? did you change any parameters in the file? Im on:

(momentum_rack_scale 1.15)
(reiza_rack_scale 1.0)
(balance_scale 0.5)
(exaggerate_front_load_feel 0.8)
(details_lfb_blend 0.7)
(bumps_lfb_blend 0.5)
(large_lfb_blend 0.4)

(engine_scale_at_still 0.2)
(engine_scale_at_speed 0.0)
(road_rumble_scale 0.0)
(scrub_scale 0.5)
(kerb_scale 0.8)

Wow 75 is quite high for me dod you change anything in the file?

 

A very big thank you to both @Karsten Hvidberg and @NuScorpii...you’re hard work and support for the community is enormously appreciated. The custom FFB files have been transformative. You’ve made a great new sim even better. @Karsten Hvidberg...you will be missed!

 

Now that we have the final file from @Karsten Hvidberg series, I've sat down this morning and compiled all of the info I could locate in the thread to create a companion file to provide additional details on each of the primary settings that can be tweaked.

This file is NOT complete and it's also possible that some of my notes aren't entirely accurate, as there were a lot of changes occurring over the past few weeks that I've only been able to catch up with thru the information provided in this thread, instead of actual testing of the individual files due to my recent time limitations.

Any help with adding information or editing this file would be greatly appreciated! I've gotten several direct messages lately from forum users asking for help with individual settings in the custom files. I think this is as good a time as any to put something like this together.

Going forward, I can put a refined version into an Excel format to clean it up if that would be preferred, as it would be much easier to utilize once it's fully updated and plotted. Another thought, previously there was an incredibly ambitious push to make these files include individual settings for each wheel base to help users get dialed in faster. We could continue to push this idea forward thru this Companion file if this is desired and add some recommended settings per wheel base?

 

New Heavy Messing update:

I and a few others had found that the traction loss effect on understeer situations could cause the FFB to go too light, feeling like too much grip was lost. Not great for improving lap times. So main aim of this update was to tone that back down to give a better feeling of grip. Same goes for loading and unloading of the front wheels. There was too much variance in the feeling of grip so toned this down too.

Main variables are:

micro_details - Road noise
macro_details - Bumps
rack_load - Weight transfer effects

The toned down effects can be tweaked with these:

load_scale - How heavy or light the steering will feel depending on load on front wheels
adhesion_scale - How light the steering will go with loss of front grip, e.g. understeer

Also for lower power wheels try increasing the min_force from 0.01. Typical values are 0.06 to 0.12.

There were a few potential bugs that have been fixed too.

Change log:
V2.3 Update:
* Toned down traction loss and front load effects. Gave too much feeling of loss of grip on understeer leading to slower laps times.
* Revised detail scales for better balance.
* Tweaked bumpstops again and fixed a bug where an uninitialised variable was used.
* Fixed a few small bugs that could potentially cause divide by 0 errors.

 

Hi Marcin,

You can insert this additional line:

(momentum_rack_scale (* momentum_rack_scale (/ (* 1100 0.5) load_tot)))

right after the existing line that reads:

(load_tot (if load_tot_read load_tot_read (+ FL_load FR_load)))


It will make the momentum buildup equal on the cars, which you can easily argue makes more sence than what's in the file, that's absolute & does not take in to account that the rack prob. has some power steering etc in many cases.
It will basically make the momentum force absolute for each
Also it then works well for trucks too.

@Slapshot82 & everybody else: This might be useful for you too? I'm using it in my local file now.

Cheers

 

Between 65 and 75, only reduced front load feel but not really noticed any difference.

 

Nice work mate, as you said a more balanced FFB overall for sure. Good job!

 

I agree,

Finally had time to race & gave it a go as well!
Feels great! Awesome progress since the last I had a go at, and balanced extremely well!

& Damn it was good fun in a multiplayer P3 session, close race. Physics does not feel quite so realistic still, or maybe it's just the missing "iceracing" difficulty factor that I'm used to that's artificial..

Cheers

 

Hi @NuScorpii , this file is top notch too, hard to tell these latest ones apart.
This line - adhesion_scale - How light the steering will go with loss of front grip, e.g. understeer-
is it higher number lighter steering, or lower number lighter steering?

 

Man iceracing..... we're doing the 24h right now, havent played it much since starting with AMS2 and probably staying that way the driving bit and FFB feels really mediocre especially in GT cars..
