Biggest settings impact on GPU?

How exactly did you verify? Still screen FPS value or benchmark run?

 

Maybe he entered a cloudy session so no trees shadows? I definitely have less fps with high in sunny weather

I also tested this at some point and I couldn't verify that High generates more FPS than Low or Mid. It scaled as expected with less FPS the higher the setting. My bet is also on a specific, unusual scenario.

 

On my system I have noticed a strange FPS drop with combination of volumetric fog and shadows.
If I have volumetric fog disabled there is only very minimal FPS drop when changing shadows from LOW to EPIC of ~5%, however if I have any volumetric fog setting enabled then changing shadows from HIGH to EPIC alone causes exponentially large FPS drop of ~20%, while changing shadows from LOW to HIGH still have nearly no impact.
Shadows at EPIC greatly improves shadow drawing range so I guess it makes sense to leave volumetric fog disabled.

Also any value higher than LOW of post processing has high FPS cost of ~25% hence I keep it at LOW.

 

i was with low to medium settings, on rain and night, and my fps was going up and down from 90 to 45 depending on the place of the track, it was a qualy session, i stopped where it was 45 and changed the settings of shadows from low to high and boom...90fps all green on open vr. I have to try also the volumetric fog thing. ACC easter eggs?!?

 

Really useful to see the good findings here guys.
So far ROG rtx2080ti oc is not complaining on highest settings but don’t mind seeing the difference some of you mentioned.
Guess the ship has sailed to ask for a built-in benchmark ...

 

Shadows HIGH instead of ULTRA, has stoped the FPS drops I had at Brandhatch at 20h00 in a race, after the bridge, the FPS dropped to 45fps, with HIGH, it's +60 now.

Mirror quality HIGH instead of ULTRA reduces the FPS drops too.

 

your gpu at 100% is normal, it's strange with a 1080ti I can race with the max AI, 29....it CPU dependant.

 

Same here, dropped Shadows to HIGH from EPIC and FPS drops where fixed, also my gpu went from 100% usage to 60% with no noticeable impact in quality
I have a 2080 with 431.36 drivers

 

But with shadow @"high", cars start looking like floating:

Shadow epic:





Shadow high:

 

are you sure you have everything at max, I will check. But I prefer this effect than FPS dros.

 

I don't understand what you mean, as I show you 2 pictures with the only difference of shadow settings.
Feel free to compare yourself, with the same result. Less shadow makes the car look like having no contact to the ground.

 

I cam confirm this. Car looks like it's floating around on the track if shadows are set to anything lower than Epic.

 

did you use ?
r.Shadow.DistanceScale=2.00
I need to test, but for me the floating effect is less important than the fps drops.

 

I have tested and it's what I thought, no difference.
HIGH


EPIC


Do you see a difference ?

HIGH



EPIC


No floating efffect. It's clear that you have not everything else at epic or max like me, there is another setting that affect your shadows, like draw distances

 

Doesn't make sense.
So you have edited your engine. ini?

 

no, the default engine.ini, we ned to understand, I have not the "floating effect", I have posted you what i have.

edit: I 've an idea, give me the track, the time you have used, I will replicate exactly your settings.

 

I don't understand this phenomenon, that you should't have the same result.

 

give me the track, the weather and the time you have used, do you have all at epic ?

 

I see a touch of floating in that 1st picture on the orange Audi's LR tyre.
