Secrets of Automobilista

Welcome to Secrets of Automobilista where I will be recording my experience, tips, tricks, resources and other helpful information as I get into Automobilista.

Secrets of X is a series of blog posts I started with Secrets of iRacing and which has grown to include Secrets of GTR2, Secrets of Automobilista, and Secrets of rFactor 2. The “secrets” part is a little dramatic but there are quite a few tips and tricks I think new users will find very valuable and interesting.

What is Automobilista?

From the game’s website,

AUTOMOBILISTA puts you in the driving seat of an advanced racing simulator to deliver a uniquely diverse motorsports experience!

AUTOMOBILISTA is extensively complemented with one of the most diverse selections or racing vehicles to be found in a racing game: only in AUTOMOBILISTA will you be able to jump from a rental kart to a 800-HP open-wheel race car; from drifting a Rallycross Evo X to jumping ramps in a Supertruck; from mastering the driving basics in a Formula Vee to managing a full 24h race in an endurance prototype; back and forth through time with historical and modern content including a sample from several decades of open-wheel racing…

And here’s a visual taste of the game,

Getting Started

In Secrets of X, I try to focus on the non-obvious or unintuitive so I won’t be covering basics like getting the game, installing it, tweaking graphics or force feedback. You’re probably beyond that yourself so I’ll focus on the hidden and obscure things.

Secrets of rFactor 2

Welcome to Secrets of rFactor 2 where I will be recording my experience, tips, tricks, resources and other helpful information as I get into rFactor 2.

Secrets of X is a series of blog posts I started with Secrets of iRacing and which has grown to include Secrets of GTR2, Secrets of Automobilista, and Secrets of rFactor 2. The “secrets” part is a little dramatic but there are quite a few tips and tricks I think new users will find very valuable and interesting.

Update 2017-10-12: Initial publication.

What is rFactor 2?

From the Wikipedia article,

rFactor 2 is a computer racing simulator developed by the American independent software firm Image Space Incorporated, released for Windows in 2013. Like its predecessor, rFactor, it is designed to be modified and is used by professional racing teams for driver training and race car development. Much of its source code is derived from rFactor Pro which is also used by professional racers and most of the Formula One teams and NASCAR manufacturers.

Bisection Search Like A (Human) Boss

Bisection search, or binary search for us developers, is a technique for finding the best value within a given range of values. This post describes tips for when you need to bisection search manually by hand (by “feel”), as opposed to when it can be automated by, say, a computer algorithm.

Bisection search, or binary search for us developers, is a technique for finding the best value within a given range of values.  Technically speaking, Wikipedia says the “bisection method in mathematics is a root-finding method that repeatedly bisects an interval and then selects a subinterval in which a root must lie for further processing.” This post describes tips for when you need to bisection search manually by hand (by “feel”), as opposed to when it can be automated by, say, a computer algorithm.

For example, say you’re very thirsty and need water fast so you pour yourself a glass of water: Pour too fast and it spills but too slow and it takes too long. You want to pour fast enough to quench your thirst as soon as possible but not so fast that it spills. The speed of pouring is your range of values (eg. slow to fast) and the consequences of the speed of pouring (how long it takes and if it spills) are your criteria to decide the best value. You try pouring the glass slowly and it’s too slow: Pour faster. You try pouring the glass faster and it spills: Pour slower but faster than the first time. You try pouring the glass “just right”: It’s fast enough and doesn’t spill. You’ve found the best pouring speed by bisection search!

Update 2017-10-26: Added sections: Bisection Hacks, and Case Study: Tuning Force Feedback Parameters in GTR2 – FIA GT Racing Game.

How much FFB can you feel in GTR2? 1/1000th of a percent.

[This is a repost of a thread I started on RaceDepartment.com and just wanted to have on my blog, as well.]

I thought the GTR2 fans would find these results on the precision of GTR2 FFB interesting. For the record, I run a SimXperience Accuforce direct drive wheel. Precision probably wouldn’t be as noticeable on belt/gear wheels.

I’ve been tuning force feedback and recording details on my blog and, in any game where I need to tune value ranges, I find myself doing bi-section searches and testing the result to find what suits me best for a particular FFB parameter.

Here’s my latest testing on this parameter in the UserData PLR file:

FFB steer force grip weight=”0.71696″ // Range 0.0 to 1.0, recommended: 0.4 to 0.9. How much weight is given to tire grip when calculating steering force.

Note 0.71696 is basically 71.696% given the 0.0-1.0 range. GTR2’s PLR files apparently have a precision of up to 5 decimal places or 1/1000th precision thought of as a percentage.

How did I end up at a super specific value like that? Well, here’s the bi-section search it took me to arrive at that value:

FFB steer force grip weight=”0.78000″, 0.785, 0.7875, 0.6875, 0.7875, 0.6875, 0.7375, 0.7125, 0.725, 0.71875, 0.715625, 0.7171875 (better), 0.71640625, 0.716796875, 0.7169921875, 0.71689453125, 0.716943359375, (0.7169189453125+ vs 0.7169677734375++), 0.71695556640625 (*, **, ***)

Yes, at every step I could tell the difference (note the “better” notation, and the “+” and “++” notations). I was choosing what gave me a better feeling of grip level while cornering.

Those last two values were (when rounded) really 71.697% and 71.696%: A 1/1000th precision difference that you could feel in the wheel.

Some might be skeptical, I understand, just be aware this is really only perceptible when you’re going hard like say for fastest lap in a qualifying session. Precision of ffb matters at that point.

Personally, I find it really fascinating to push an old game like GTR2 from 2006 this far and find out it can deliver that kind of fidelity on a modern direct drive wheel.

*Yes, to update those values I have to exit GTR2, edit the PLR, and start GTR2 back up again. A real pain but worth it when you start to feel the car as it was meant to be felt.

**My “bi-section searching” deviates from a strict bi-section search in that sometimes I experiment and try values that aren’t strictly a bi-section the previous two values. I find this can help when I’m frustrated with the feel and need to find my bearings with a bigger jump which I then narrow down again with a regular bi-section search.

***If you’re interested, I’ve attached my PLR so you can see all my modified FFB values. The car was HQ F575 GTC and the track was HQ Brno. I run 60hz vsync.

That awkward moment… when you see a panhandler at the intersection as you’re driving your daily commute to and from work. Each and every day, the same man or woman for a few days or weeks at a time, then maybe a different person for a while, there most days of the work week, and most days you hope to avoid them or to avoid eye contact, at the least. A few more intersections, then you’re home free – for one more day…

‘Lord, when did we ever see you hungry and feed you? Or thirsty and give you something to drink? Or a stranger and show you hospitality? Or naked and give you clothing? When did we ever see you sick or in prison and visit you?’ -Matthew 25:37b-39

What is GTR2?

From the Wikipedia entry,

GTR 2 – FIA GT Racing Game is a sports car racing simulator developed by Blimey! Games and SimBin Studios (later Sector3 Studios) for the x86 PC and is a sequel to GTR. Since its release in September 2006, it has received widespread acclaim. The game simulates the 2003 and 2004 FIA GT Championship racing series.

And here’s the official game trailer,

Creation doesn’t matter to my faith. Right?

Note: This post is a point-form summary for a small group discussion that I compiled from the last section, “Real, Eternal Value Intended by the Original Authors”, of my previous post Answering Genesis 1 and 2 Contradiction Claims.

Update 2017-07-29: Our small group discussion brought up some interesting points. Here’s some small updates I sent the group after the meet up…

Update 2017-07-29 (1): If anybody’s interested, here’s an AiG article on the ‘topical parallelism’ of creation days that Paul brought up (spoiler: it’s there on a surface read but the devil is in the details, as always; also like we discussed there’s no saying you can’t use various literary devices in different kinds of literature, even historical, it doesn’t take way from it): https://answersingenesis.org/blogs/ken-ham/2011/12/10/its-not-so-parallel/

Update 2017-07-29 (2): I also didn’t know where to go with the point made about Christ needing to be a blood-relationship to a real Adam versus Christ atoning for our sin (we all sin, no Adam needed) or atoning for our sin nature (from Adam, so blood relationship required). In evolution, there’s no first Adam so we’re not blood related so biblically the kinsmen redeemer idea doesn’t work (so did Jesus act do anything?) But if Jesus only died for our sin acts then maybe a first Adam isn’t needed anyway. I don’t have a solid answer, it’s worth some googling, but apparently it has to do with Original Sin (sin nature) vs Imputed Sin (Adam’s sin is “credited” to us). The first is dealt with by the Holy Spirit through sanctification over time, the second was dealt with by Christ’s righteousness being credited to us (so would require a real first Adam for it to make any sense). http://www.desiringgod.org/articles/what-is-the-difference-between-original-sin-and-imputed-sin

Update 2017-07-29 (3): Btw, I don’t pretend perfection in understanding all this is achievable, but I just love how when you go digging usually you find these things have already been covered and they fit right in.

Note: This post is a point-form summary for a small group discussion that I compiled from the last section, “Real, Eternal Value Intended by the Original Authors”, of my previous post Answering Genesis 1 and 2 Contradiction Claims.

Is Genesis meant to be taken plainly?

  • What was the author intending to convey?
    • Poetry, parable, etc., or history?
    • No Jewish poetic forms (eg. parallelism absent), scholars agree
  • Jesus and the Gospels said they were given by Moses
  • Genesis 12-50 are not really disputed but 1-11 are
  • Colophons on tablets indicate knowledge known to the author up to the end of the tablet indicating historical records
  • Numbered days, ‘evening and morning’ language, strong support for ordinary, 24hour days
  • Similar language structure in Numbers 7 shows evidence original language choice in Genesis 1 specifically intended ordinary 24hour days as we experience them

Ever feel like God is silent?

Ever feel like God is silent? Jesus said the fateful words on the cross, “My God, my God, why have you forsaken me?“, Psalms 22:1, a prophetic picture of Jesus’ crucifixion, but the very next verse says this, “My God, I cry out by day, but you do not answer…” Even the Son of God experienced the Silence of God. Take heart, then, because ‘we have a High Priest, Jesus Christ, who has been tempted in every way, just as we are and yet did not sin‘ (Hebrews 4:15b), and now, because of this and through the Cross, ‘Jesus lives forever and has a permanent priesthood – so He is able to save completely those who come to God through Him, because He always lives to intercede for them’ (Hebrews 7:24-25). Selah.

I have told you these things, so that in me you may have peace. In this world you will have trouble. But take heart! I have overcome the world. (John 16:33)

For God so loved the world that he gave his one and only Son, that whoever believes in him shall not perish but have eternal life. (John 3:16)

Misericordia, Soli Deo Gloria

Money is a Test

Whatever you have, God has given it to test your loyalty, allegiance, and heart. Judas’ soul was cramped and traitorous; money revealed that. Joseph’s soul was generous and loyal; money revealed that too. And “where your treasure is, there your heart will be also.”

The following is an excerpt from James McDonald’s “Found a Faithful Steward” blog from June 23, 2014. It hit home with me because it started at basics and progressed beyond to some things we don’t often consider in how we think about and use our money.

Jesus said,
“For where your treasure is,
there your heart will be also”
Matthew 6:21

Money is a test of your:

Work ethic: While not universal, generally speaking, if your wallet is empty, you ought to look closely at your work ethic. How hard do you work? How diligently did you work, save, and invest in your twenties and thirties? The test of money hints at the longitudinal arc of your work ethic.

Self-control: You’ll never experience financial victory until you spend less than you make. Some people spend more than they make for years or decades. They’re failing the test, which often leads to financial bondage, tension, and misery in their homes.

Integrity: How did you get what you have? Did you cut corners or twist the truth to win a deal? Withhold taxes? Neglect tithing? Jesus taught, “Render to Caesar the things that are Caesar’s, and to God the things that are God’s” (Mark 12:17). The money test demonstrates your integrity—or lack therof.

Love for people: When you’re able to meet someone else’s financial need, do you? Can you recall people you’ve helped? Perhaps no one knows. Perhaps you didn’t get a tax deduction. You simply helped and loved others. If so, you’re passing the test.

Love for God: Jesus said more about money than He said about heaven and hell combined. Not because it’s the most important subject, but because until God gets hold of people’s finances, He doesn’t truly have their hearts.

Whatever you have, God has given it to test your loyalty, allegiance, and heart. Judas’ soul was cramped and traitorous; money revealed that. Joseph’s soul was generous and loyal; money revealed that too. And “where your treasure is, there your heart will be also.”

An Empty ‘Bottle of Water’ with Daniel Pech -Selah.ca Guest

Why do we espouse Young Earth Creation? Earth is a member of the total cosmos that God created. Would it not be more accurate to call it Young Cosmos Creation? Today, it is popular to think of Earth as a member of ‘the cosmos’. Secularist cosmologists even think of her as entirely the product of him. But not even the cosmological constants are sufficient; their fine-tuning for life is necessary, but not central. There must be an Earth.

I’m happy to introduce a paper by Daniel Pech, an enthusiastic creationist with lots of ideas, in which he proposes a reading of Genesis 1 that includes subtly more nuanced perspectives between the heavens and the earth while retaining a young-earth creationist perspective..

Daniel contacted me after reading my post concerning the complementary nature of Genesis 1 and 2 (as opposed to a self-contained and contradictory nature).

You might be interested in getting to know Daniel a little bit more. If that’s the case, head over to my post entitled Daniel Pech – Bio, Aspiring Creation Writer -Selah.ca Guest.

The first section below, The Best of Both Worlds, is a primer to Daniel’s main idea in his paper on a reading of Genesis that highlights what Daniel believes is a lack of reading the full ‘dimensionality’ of the text.

The second section is an excerpt to Daniel’s paper which more fully reveals his argument and direction.

I hope you enjoy the introduction and take a look at his full paper if you’re interested.

The Best of Both Worlds
by Daniel Pech

The best of both the physics and terrestrial readings conceivably can both be that meant by the author of the account.

By a perhaps very simplistic analogy, suppose we wanted to make a pictograph of a particular portion of a particular year of the Tour De France in which some or even all of the riders saw, on a particular portion of the road, an unusual event in which a flock of birds were on and near the road eating seeds. Here is a single pictograph every bit of which serves to account this particular instance of this particular year of the Tour De France:

O<O O<O
O<O O<O
O<O O<O

Notice that the selfsame set of data comprising the above series of shapes can serve simultaneously to tell both halves of the whole basic story.
