VR Discussions, Questions & Feedback

Ernesto, muito obrigado! Your setup worked super well in terms of cranking up my settings.
My fps is not super stable, but then again, it never was, but im able to squeeze so much more performance out of my quest3! i went a bit more conservative FOV-wise with 0.85/0.85 but pretty much everything medium or high in game.

Thanks again mate, really appreciate you sharing your settings. merry xmas!

 

As I said, there's no setting to change this behavior. Please try driving a 911 GT3 on the Nordschleife in VR and pay attention to the lateral/horizontal wobble of the outside world. It can be seen on other tracks as well, but the unevenness of the Nordschleife makes the bouncing of the stiff suspension particularly pronounced, while the lateral wobble of the world is extreme.
I'd like to drive AMS2 more, but its behavior makes it too tiring in the long run. US stock cars with Daytona are great, for example, as this problem is less noticeable there.

 

I like to set horizontal FOV to the max I can see using Quest and my glasses, and keep vertical FOV to emulate a racing helmet. With VR we racing with a scuba mask anyway... If you lower a lot vertical FOV you can go for a lot of ULTRAs, and I believe the trade off is great!

Merry xmas!

 

G forces in camera settings unlock the camera from cockpit, so, it's smooth ALL outside track moviments with real g forces from game engine, without go crazy in banked turns. With good g forces horizontal camera moviment, in VR you can keep your sight in a point when your car is sliding like crazy, as your eyes can do in real life, and is great to get some g forces feedback that we don't have in sim racing.

I noticed few people uses this setting, but in VR it's a must.

 

Hmm, apparently I can't describe the problem adequately, because it can't be fixed with any of the AMS2 camera settings. In real life, the outside world isn't precisely synchronized with the vehicle's rotation, but it is in AMS2. Merry Christmas

 

Do any other sim do it like irl, so we can understand what you want to say?

 

Ac1 also has this problem, but it can be solved with the CSP and NeckFX.
Raceroom and LFS, for example, don't have this problem.
Let me try to explain it technically:
When you drive a car with a stiff suspension and high tire grip into a corner with bumps, the car bounces accordingly. The car's rotation in this case isn't smooth, but jerky, due to the loss of tire grip. In AMS2, this jerky rotation is directly linked to the view's rotation, which isn't the case in reality. In reality, the lateral jerking movements are filtered out. Essentially, there's no filter for the "lateral" movement of the external environment; the current filters only correct the wobbling from above and below.

 

Now with full understanding the issue, I can Tell that G FORCE lateral moviment do exactly what you want. It's a rendered world, and the camera need to bem anchored to something, and in this case, it's the car you are driving in VR. In VR, the point of view try to be locked to the point you are looking at, but your car are moving in all axes. G FORCES does exactly what you want, but it's Impossible to ged rid of car moviment in camera, or you will have a statonay camera in some point of circuit. Will try to make a video, just a moment.

 

Then it's either a physics engine issue, which is why it doesn't happen in Raceroom, or the jerky movements are dampened there. In any case, it's very tiring for the eyes. In reality, you're not exactly synchronized with the rotation either.

 

You can lock view to horizon and add 100 Head moviment. You will have 100% view locked to point of view (besides obviously the car moving on track) and filter all bumps and car moviments. But give a try to G FORCEs lateral, it's the only sim that I really can "feel" lateral g forces and car rotation in VR, with all the glory some hate in AMS2: FLOATY FEELING LIKE A REAL CAR!

 

I've already tried all the settings. Including the setting where the cockpit rocks from side to side. Despite that, the outside world still jerks sideways; I tested it. Unfortunately, it's only comfortable on flat roads with cars that have a soft suspension.

 

Tried now without any camera damping, all locked to car, and even with some damping that you can't get rid in settings, really the track rocks side to side in bumping curves in formula trainer. But with a lot of lateral g forces, this "feature" goes to the car moving and I don't feel noticeable outside lateral jerk looking apex and exists. But now really can understand, because I always uses g forces in VR. Maybe other sims don't simulate this small changes in grip in these conditions.

 

I use an SR2 Sim-Motion system, so I can't use the additional movement and simulated G-forces of the cockpit. I know it's not noticeable on the monitor, but I only play sims in VR now.

 

With this info, I believe your problem in more complex, because a motion system sim rig I believe don't have the speed response to achieve the correction that ingame visual filters do, and all are more complicated. I only use Bass shakers, and as can see in video, the car moves like hell side to side in turn entry but the outside view is smooth. If you uses g forces in camera settings with a motion rig, i thing all will be crazy as hell.

 

Problem with what he described is that not everyone can feel it. Like everything: some people do not have motion sickness at all, some need really good horizon lock, months of VR legs building etc.
I am the second type, and I have exactly the same issue with some cars in AMS2.

 

If you set the video speed to 0.25x, you'll notice the stuttering. Pay attention to the edges of the screen during fast, tight turns. The rows of trees appear to jump, unlike those further away. This is more noticeable in VR than on a monitor.

I suspect it's related to how the Madness Engine renders speed. The same problem existed in LFS until recently. Since the last update, the physics engine and the rendering engine are clocked differently. Since then, the image runs much more smoothly, even at the edges.

If that's what I think he means,
I don't believe camera settings or VR options will help. It's the rendering pipeline or a similarly deep-seated problem within the engine itself.

 

It's not stuttering, it's a bumpy turn really. The way that camera moviments smooths far view is moving more things near, so, more noticeable are side objects not in focus shaking like hell, everything normal.

Our brain and eyes are much faster than a VR headset to stabilize the point of vision focus, at least without eye tracking.

 

It has nothing to do with my SR2 system, but the solution for the excessively lateral cockpit movement is even more unnatural when using the motion system.
If you have a car with a stiff suspension and you focus on a point in the distance, the image wobbles extremely from side to side as soon as the tire loses and regains grip in a corner.

It's not visible in the video, but the cockpit moves extremely unnaturally from side to side...
It shouldn't have to do that; the short lateral jolts need to be eliminated.

I think the original problem is the tire calculations and the stiffness of the tire sidewalls, which then manifests as an unnaturally harsh loss and gain of grip.
An extremely positive side effect of fixing this problem would be that the entire sim would feel "significantly" more realistic.

 

I really don't know If more "realistic" is the way to go:

As I said, our eyes and brain are really good to smooth things, and I think AMS2 does a great work in VR, so we don't puke in 30 seconds of VR racing...

 

Every sim can now do without motion sickness; that shouldn't be the goal.
This shaking is just as tiring for the body. It should be in everyone's interest to be able to use all the series in AMS2 with VR. Because in terms of graphics performance and the variety of vehicles, I see AMS2 as being way ahead.
