iRacing.com – Ruf Reality Check Video

Sim racing video maker stabiz has put together a new iRacing reality check video, using the newly-released Ruf RT-12R race car.

Sim racing video maker stabiz has put together a new iRacing reality check video, using the newly-released Ruf RT-12R race car.

The video shows a lap around Interlagos in both the semi-fictional Ruf race car and the very similar Porsche 997 GT3 race car.

    stabiz makes it cool. but this guy simply nailed it – https://www.youtube.com/watch?v=9jQouH8oCGo

    Very good video. That shows the differences between real and game. In game, car is way to rock solid in it’s body movements. (not caused by locked to horizon camera!) Like the track has no bumps? Also the steering input is far simplified in the game. Just immediately turn full lock until you’re coming out of the corner. While in real, the driver is feeling for grip with the steering wheel, until he reaches the apex. Then turns full for just a second.

      Sorry but apparently you don’t have the game or you just have a bad driving technique judging by your comments.
      When i’m driving i can assure you my steering inputs almost match the real car when driving on the limit and i’m searching for grip in the same corners as the real video shows.
      Yes you can apply full lock and take a corner in game but this doesn’t mean it is the best way or the fastest way to take a corner.
      Can i ask you what your best time on this track is cause i’m pretty sure that you aren’t close to top times if you apply full lock?
      If i want to drive at a decent pace i don’t use full lock because it only makes your car understear as it does in real life.
      Concerning the bumps the camera settings have a huge impact.
      The camera mounted in the real car can exaggerate the shaking also because it is not mounted firmly on the chassis.
      btw. There are more settings that impact the movement you see in videos then driver head locked to horizon).
      In this case it was maybe better if the ingame setting allowed driver head wobble because the camera in the real cars also wobbles. Now in the video you see the dash going up and down while on the right side the camera is perfectly stable in comparison to the dash.

      I’m not saying iRacing is perfect but i think your comments are exaggerated and don’t match with my experience in the sim at all.

        Car clearly responds to road bumps in the real footage, whereas in game it seems like it is “hovering” rather than touching the road surface. Anyways, it should be relatively easy to represent car body roll in game. Adds a lot to immersion and sense of speed.

        I’m going by the video, as I stated. There is a tiny steering wheel graphic in the iRacing side, representing the wheel movements. Anyone can clearly see they don’t match. As for the missing bounce. No camera adjustment will remove the cars body bouncing against the road graphic. Even if the camera is locked to the horizon. The body of the car will still be moving up and down against the graphics outside the car. Sorry if a little criticism offends you. I wasn’t picking on iRacing specifically. But just the general state of Sims. Though not all have this same problem.

        One of the issues with comparison vids is the number of variables. Here, I’m thinking mostly setup. Tweaking the tire pressure and dampers could make the iRacing car shake like the video I’m sure. The question is whether that would make the comparison more fair (the cars aren’t set up similarly in the video) or less (artificially stiffening the car to increase the bumpiness transmitted to the camera). And that’s even before we get into the nuts behind the wheel.

        I would agree it’s a bit of an overall sim thing, though. Infinitely rigid chassis with rigid camera mounts, and likely no engine vibration transmitted to the camera (for an extreme example of bad camera mounting: http://www.youtube.com/watch?v=xpwLcfzm760 ). And of course, when a game tries to add those effects to look more realistic, we tend to get mad at them for using ‘gimmicks’ (Shift comes to mind). Same with the audio, really. People tend to use onboard camera footage to justify whether a sim did a good job of capturing car audio or not, when most onboards are tiny, low quality mics that are distorting due to the high volumes.

        As a quick test, though, put your thumb right on the top of the dash of the real car’s video (in the article), then watch as the dash’s location changes as he goes around the course. It looks to me like at least part of the motion we’re seeing is that of the camera mount, rather than the car’s chassis itself.

        How are the wheel movements going to match?

        One is a real video, the other represents someone driving a car in a sim, who obviously was making different steering inputs to the real life driver.

        Or are you saying if you ran a lap in a sim in car and then we compared it to a real life clip from the same track, that your steering inputs would be identical to he real life clip?

        Check the AC clip below and compare the steering, certainly not identical.

        I would like to point out that the main difference is in setup/weather. I clearly have more understeer than he does, making me use more steering lock earlier. Just a few degrees lower temperatures in iRacing (Grand Am runs the same track with this car in slightly different weather) makes the car slower but also shifts the balance a bit, giving more front bite and oversteer with the same setup.

        Also, this was not an attempt at making it look similar, that is the pole position lap from RUF Cup this week, just slowed down playback to match better, and I was surprised when I saw that video and how similar you drive to go fast in the sim.

    For a laser scanned track Interlagos shows rather “flat” in iRacing, judging at least by the amount of car wobble in the real footage.

    • Anonymous

      I mentioned below, put a reference point on your monitor and you’ll see the car’s dash on the left moving, indicating the camera mount is moving. That means not all of that wobble is the chassis, so the iRacing clip should seem more smooth since it’s a ‘perfect’ camera mount.

    • fkkamil

      Your conclusion is flat.

      • John Karagiannis

        Your sense o’ humor is wobbly.

      • fkkamil

        Beacuse your comment was like “haters gonna hate”. U guys still compare shaking poor GoPro video with perfectly mounted virtual cam in iR. You musn’t judge track bumps by camera shake. It makes no sense.

      • John Karagiannis

        Chill out pal, I am no hater, just my sense from the video. Moreover, there is no such thing as “perfectly mounted virtual camera”.

        What do you think about the in-game camera makes it not ‘perfectly mounted’? What he means is that the camera has no inertia and the mounting is perfectly rigid, whereas a Go Pro camera will wiggle and shake within its mount.

        In other words, a sim camera captures the chassis movement, while a real camera ends up adding the chassis movement and that of the vibration and acceleration of the car.

        I use Motion Cockpit View in iRacing, which makes the driving view move in response to the car’s acceleration. That’s the motion missing in the above video that’s present in the real car, it’s a result of the cameras being different, not the track being flatter.

    This car is so much fun. I was pretty much done with iRacing and just running AC and loving it. I gave iRacing one last chance and bought the Porsche… Honestly haven’t touched AC since. Awesome car (not 100% perfect) and awesome online racing!!!
