GTX 1080ti vs GTX 2080ti in VR on racing sims

[RobertR1]

Giving this guy credit for a comparison video done right. I’m so glad an actual sim racer who has good knowledge of computers and game settings did a sim racing only comparison in VR.

I think some people will be surprised at the difference in VR performance compared to 2D gaming results.

For sim racing in VR, this video puts things to rest.

Edit: mods can you please edit to say RTX..old habits. Would you please move this to “computech” section where it should be.

While it's great for showing how much more performance the 2080Ti gives in sim titles, his AC settings were all kinds of derp.
I hope it was just done for the sake of the comparison and he wasn't actually using those settings day to day and being unhappy about 45fps.

He could've been rocking a smooth 90 with the 1080Ti with better graphics and little to no loss in fidelity.

Hs starts with:

- World detail - minimum
- Shadows - 512
- Reflection res - 2048 / static
- PP - Max with glare off
- SS at 2.0

and gets 45fps...

I try the same track, same amount of cars and GBW misty at sunrise with these settings and shader mod with car/track lights and VAO (8600K @4.8 / 1080Ti @1950-2000):

- World detail - Very high
- Shadows - 2048
- Reflection res - 512 / static (or 2 faces with SS at 1.4)
- PP - Med / Med
- SS at 1.5

and get 90fps

Dropping those graphics settings for the sake of a pretty much imperceptible 0.5 bump in SS and then still getting 45fps is just silly in my opinion.
I tried his settings too and I know which one I prefer.

So while I do agree that his video is a good showcase of how much better the 2080Ti is in these games using VR, it's perhaps a bit misleading for those that don't know any better.

He might have addressed this after doing the other comparisons, but I honestly couldn't be bothered to keep watching after the AC bit

1.5 is most definitely the sweet spot. Incomparable to 1.0, it's just so much better. 1.5 to 2.0? Not that much difference to be honest. At that point, you settle on 1.5 and turn as much in game AA and settings up as possible before warping. Even then, if you don't mind running 45hz ASW, it's still probably not worth running 2.0. Might be better off just keeping the headroom for potential rain / extra visible vehicles and race starts. I'm having so many problems with VR at the moment that I'm getting used to just running ASW full time and accepting warping in favour of keeping things smooth.

comparison video done right

I have to agree 100% to that statement, as a VR 1080ti user, I am glad a better card exist,even though, with the right settings the 1080ti performs very well for me,
The 2080ti seems to be way better for VR.

I'd be a lot more interested in 1080ti VS non ti 2080. Similar price atm, similar performance. Differences in vram and shader counts.
Apart from Dlss and rt: how is the performance in VR?

I know there are already benchmarks. Just saying that I think such a video would be definitely interesting. Maybe more interesting than the two ti's compared.

Good luck getting 90 fps with Dynamic Light mod the guy is using.

The difficulty you'll have there is that no one with a 1080ti would be willing to dump it for a 2080 thus no benchmarks are likely by the general public.

If someone has contacts with some reviewers, that's probably the best bet.

Not true.
The settings I posted above gave 90fps with all of that stuff switched on (inc stereoscopic mirrors) + 4xAA / 16xAF / Low smoke.
Sure, the available headroom is pretty low and it can dip to about 85-87 on very brief occasions, but with ASW off, those tiny blips are unnoticeable and it's at 90fps about 99% of the time.

It depends on the track, but you can sometimes get the usual little drop/fluctuation at the start of the race and T1 (sometimes into the late 70's), but that clears up pretty quickly and you're back to rocking 90.

AC rendering in VR is very CPU bound. Most stuff, world details, reflection, shadows, mirrors, opponent cars are hitting single CPU rendeeing thread.
AA, AF, and SS are mostly GPU, so techically to show GPU difference, pushing SS during the test is the right thing to do.

 

[Petey Spangles]

I don't think that's being disputed here.
Also, I don't think the guy doing the tests was thinking that when he did them, going by his response to me:

Which settings should be changed to make it better? Can you share your setup? I'm constantly trying to find the best visual quality.

Going by that, I think he was genuinely running those settings on a daily with his 1080Ti and suffering poor framerates and compromised visuals because he thought maximum SS was the key to it looking good.

The real test would have been PC2, those three games are pretty easy to run and look good on a 1080ti.

Some more VR 1080ti vs 2080ti comparison here from SweViver, not Simracing specific, but you can get the picture of performance for high FOV headsets.

He will make some simulators specific videos in future so that will be more interesting.

It seems I'll be getting some used 1080ti, still deciding on CPU, but Ryzen seems better choice then overpriced Intel, I hope more people will say no to these crazy prices from these 2 companies.

Looking to upgrade my 4790k but nothing makes me want or need to atm. I have a gtx1080ti and possibly the Ryan zen2 is where I’m leaning. Disappointed in the 2080ti skipping at least a gen

Locking the FPS at 45 i still not know how much slower the 1080TI is.
As an example, the 2080ti doing 90+ fps and the 1080ti only reaches 80 fps, but he locked the FPS to half the refresh rate, so i still dont know what margin it is faster.
(EDIT)
But as any nVidia release for the past years, the new generation is about 30% faster than the same class of the previous generation.
