Real triple monitor
in DiRT Rally 2.0

In DiRT Rally 2.0, running three monitors stretches and warps the image out to the sides. That means motion sickness, discomfort, and no way to judge a real distance on the side screens. I quit the game over it, until I decided to try to fix it. That is how TrueTriple was born, and it worked so well, and I enjoyed it so much, that I turned it into a tool anyone can use. Back me on Patreon and I will keep building solutions like this one.

Get the mod

The same start line across three screens: on top with TrueTriple, perspective corrected on the sides; below, the game's stretched mode. — Same start, same rig: on top with TrueTriple, below the way the game stretches it.

What you'll feel

This isn't a number in a benchmark. It's the first time the game shows you the world at real scale.

You're inside the car

The sides stop lying to you. The A-pillar, the mirror, the edge of the hood end up where they belong. For the first time you feel like you're driving from inside, not looking at a wide photo of the car.

Distances are distances

By projecting with your rig's real geometry, everything is the size it would be in real life. Corners read better because the braking point is where your eye thinks it is. It changes how you drive more than any hardware upgrade.

Your seat, your way

You move the viewpoint inside the cockpit forward, back, up and side to side, until the position is yours. In any car, without the game's ridiculous limits. And it remembers where you left it.

With Nvidia Surround or AMD Eyefinity the game sees a single very wide monitor and draws everything with one camera. The side panels come out stretched. TrueTriple gives each screen its own window into the world.

Without the mod

The three screens are a single flat plane. Anything in the side thirds gets stretched, and the wider you open the angle, the worse it looks.

With TrueTriple

Each monitor gets the perspective it deserves based on where it sits and how far it's angled. Turn your head and what you see is what you'd see out the window.

What's included

It's finished and working, not a proof of concept.

Correct perspective

Three independent frustums calculated from your rig's physical geometry. The image it always should have had.

Sky, shadows and reflections

Everything the game computes in screen space is re-corrected per monitor. Nothing swims or misaligns on the sides.

Minimal performance impact

Now three cameras have to be calculated instead of one, so there's some cost. I won't lie to you. But I optimized the mod thoroughly to keep it as small as possible: the performance drop stays under 10%. In practice, you'll barely notice it.

Free camera in the cockpit, with saved positions

Position your head to the centimeter in any car, moving it forward, back, up and side to side, and save that posture into a slot. You can keep several per car and switch between them with one key: one for your usual view, another further forward for the narrow stages, whatever you want. The mod recognizes which car you're in by itself, so each one has its own positions and remembers them for next time.

It calibrates itself

It reads each frame's real projection live: works with any camera, FOV and resolution, without you touching anything.

What you are supporting

I made TrueTriple for myself, to play the way I wanted to play on my own rig. I shared it afterwards because it turned out to be useful to other people. It is not a company product: there is no team behind it, no QA department, no support desk. There is one person.

It can have bugs, and it can break when the game updates. When you subscribe you are not buying a product: you are backing the development, and in return I give you access to what I am building. The Patreon is also where it gets told from the inside: the dead ends, what breaks and why, and where this goes next.

The same Patreon puts out Assetto Gallery, which sorts out the car and track library for the people running Assetto Corsa. Take a look.

No fine print: terms of use and support.
