Floating Cars ??

[PaulAM]

With anything other than epic shadows, my system shows the cars in a way that look like the cars are slightly floating along the track instead of rolling.
Also the car shadow edges flicker and wobble.
It looks really stupid and I'm hoping someone can help with settings.
I presume that I've done something wrong and the shadows don't actually have to be on epic to get rid of hovercars...?

I have this too. Also, while watching a replay, how do I explain this, the car shows ghost images in it's wake. Really weird and off-putting.

That's normal if you are using TAA.

Thanks. I'll change it. To what, I have no idea.

Try changing to FXAA in the ingame video options. That should cure it.

I really wish they would give us the shadow options like they have in Raceroom and the separate option's added for car shadows and contact shadows.

I have never spent as much time on ANY sim trying to fine tune GFX settings like I have with ACC. And while it has gotten better with each update, there's still a lot of trading off to try to reach a happy medium, especially running triples.

Now I never use or put much trust in GeForce experience optimization settings as it usually turns on a bunch of stuff that's really not necessary. I know everybody's will probably differ (single screen vs triples, cpu/gpu power etc) but for me I was kinda shocked to see it suggested setting just about everything to low and no AA at all.

Are we still seeing this post 1.3 update? I was messing with the shadow settings today to try and sort slow downs I was having with the day/night transition. I've settled on lowering draw distance and shadow quality which seems to have helped, and also haven't seen any floating cars today on 1.3.2.....

 

[PaulAM]

1.3 yes for me - still hovercars unless I put shadows to Epic

 

[FruchtigerZwerg]

same on me

Try this .ini file ! It works well for me with shadows and also give good CPU headroom ! This one really is magic imo i do use epic at times buthigh still looks pretty good until the cars are a fair bit in front then the under car shadows turn off Also these are my settings for 1080ti/7700k and 1080p triples

I must say this engine file is very good indeed, I've been using it when I race in VR. I did notice the shadows under the cars disappearing when I tried it on triples as well, really stands out on replays. However I think your on to something good here.

I have all settings set to Epic and noticed this yesterday, even when the cars are in the pits they appear to be floating rather than making contact with the track.

 

[SwaggerJacker]

I'm going to try that file when I return home! Thanks!

 

[SwaggerJacker]

Now, for the daft question. Where do I drop this puppy?
Never mind. Figured it out.

I have this problem since day one. Cars look like they float.

I just tried both shadow settings on max, no improvement. I also changes nothing about fence shadows racing you.

I also find it telling that the people who deny the problem, guessing from replies I see, are in my killfile

 

[SwaggerJacker]

That file worked for me. Frame rate jump, however, I'm getting some stutter that I wasn't experiencing before. Even while practicing with frame rates hovering around 90, I'm getting stutter around corners. The floating cars are now gone. I'm going to revert back to my old engine ini. I can't take the stuttering. Will see if it's the new file, or just a PC issue.

 

[SwaggerJacker]

Still not sure why the stutter. But I say the file is a success.

Although it’s primarily about vsync/freesync monitors, there’s some interesting information here about stutter at high frame rates:

Thanks much. Ill check it out!

 

[maelstrom]

I don't think it is hardware or resolution depended, if you think you don't have the issue, you just have not noticed it yet.

So you think some (many) of us are just not as observant as you? That we comment on things without actually checking them out?

Maybe the underlying problem is the same for this and shadows under the car, who knows, there are several threads about that in the official forum but no dev answered.

Perhaps it’s just very difficult to diagnose something that doesn’t seem to happen to everyone (or that the devs can’t reproduce). Look at Monza races on YouTube - do the cars always seem to be floating? The same applies to other tracks.

 

[Gergo Panker]

You have control over two parameters, shadow distance, which sets the size of the shadow map and shadow quality, which sets the resolution. The former sets how far the dynamic shadows are rendered, the latter defines how crisp it is.
I recommend keeping shadow distance higher than quality, and actually keeping the distance quite high at all times as it's not as heavy as shadow quality.

Higher image resolution of course needs higher settings because the rendered image consists of more pixels, thus the same shadow map covers a smaller area.

All the engine.ini tweaks and magic settings tend to turn off shadows or turn them down significantly, so don't expect wonders there.

Under-car shadow are only visible when they are shadowed by the dynamic shadow due to how ambient occlusion works in the engine. So if you turn down your dynamic shadows, you'll also likely lose the fake shadows under the car.

 

[PaulAM]

Default settings - no tweaks. 6700k, GTX 1080, 1440p, mostly epic or high. I haven't done anything clever, I just don't get the floating cars. Sorry I can't give you any magic settings.

if you put your shadows on settings OTHER than epic, do the cars look like they float?
