Who is expecting some downgrades?

Well considering DICE's rendering engineer detailed how they are improving performance and it included "downgrades" - me?

Nice! Waiting for DX 12 sli too, so I can benefit my 2x 2080ti in DX12, and not just DX 11.
180-230+ fps in BF V in 3440x1440 DX11 Ultrasettings 🙂

Was expecting some shady practices like reducing the quality. Lets wait and see.

Like I said, DICE has already detailed how it's getting this additional performance - It's a combination of bugfixing, optimization of the renderer to start raytracing earlier in the frame and using a few tricks to avoid raytracing in areas where you shouldn't see it (I'd argue this is downgrading) or restart it where it failed as opposed to redoing the entire ray.

I highly suggest reading this article - it goes into depth about the optimizations going into this patch.

Up to 50% - and there is the frozen lake scene with less than 15% performance gain. So it can get about 35-45 average on 4K with RTX medium-high-ultra with DXR with a 1200$ 2080Ti. Impressive one.
2070 gets much less bump from this patch. Anyway, shxxy result still.

Well, I'll gladly see videos of this in the future. Not bringing me to buy an RTX card in the meantime...
I hope you'll get your SLI under DX12 soon.... I just don't think this will happen.

Awesome looking update, cant wait to test it out 🙂

Lol XenthorX posts on Guru3D all the time. Great guy!

With the new Nvidia driver, and the patch great news that ray tracing is improving. Now let’s see if DICE is able to be above 60fps at 4K ultra on a 2080ti eventually
Sixtyfps
Im looking for the Tank map. I hope its Battle of Kursk

Improving DXR performance... by turning shit off!

In that video, you can already see noticeably less things being reflected in the patched version

Then you'd argue culling is "downgrading, right?
Denial
AFAIK they aren't doing any additional culling of rays aside from what's already in. They talk about culling in that article but that's already part of the quality slider.
But yeah - if they are doing additional culling it's downgrading. Personally I don't care if they downgrade the reflections as long as it's truly reflecting the scene and is relatively unnoticeable. I mean the game has particle leaves spawning out of random terrain that if you stop and look at it, it's terrible looking - but in motion, jumping around and blowing people up with random leaves everywhere - it pretty looks cool. Same thing for reflections - I don't care if I pause a video and notice like some previous reflection looks slightly worse as long as the plane crashing through the air down on my head is rendered in the puddle complete with fire and smoke.
Either way I'm not spending $1200 on a 2080Ti so downgrade or upgrade away. I won't notice lol

Sure. Let's cut the Raytracing around half in games, just because it's too much for any present graphics card to handle it (2080 Ti included) and let's get that same amount of performance gain. Raaytracing is very nice evolution of graphics from Nvidia, unfortunately the graphic cards today are not ready for it, maybe only up to 1080p gaming!
HeavyHemi
Culling is not downgrading. Culling is removing parts of scenes that are not in view or, in this example. ray tracing parts of scenes that are not in view. So I disagree. The article isn't about your preference for spending. It's about the tech.
I was rolling my eyes all all the silly comments about needing to 'buy a 1080p monitor' to use a 2080 Ti...as if BF V required you to run all your other games at 1080p...something you seem to think too.

Because both of you are too lazy to read the article I linked:
[Quote]One of the optimisations that is built into the BVHs are our use of “overlapped” compute - multiple compute shaders running in parallel. This is not the same thing as async compute or simultaneous compute. It just means you can run multiple compute shaders in parallel. However, there is an implicit barrier injected by the driver that prevents these shaders running in parallel when we record our command lists in parallel for BVH building. This will be fixed in the future and we can expect quite a bit of performance here since it removes sync points and wait-for-idles on the GPU.
We also plan on running BVH building using simultaneous compute during the G-Buffer generation phase, allowing ray tracing to start much earlier in the frame, and the G-Buffer pass. Nsight traces shows that this can be a big benefit. This will be done in the future.
Another optimisation we have in the pipe and that almost made launch was a hybrid ray trace/ray march system. This hybrid ray marcher creates a mip map on the entire depth buffer using a MIN filter. This means that every level takes the closest depth in 2x2 regions and keeps going all the way to the lowest mip map. Because this uses a so-called min filter, you know you can skip an entire region on the screen while traversing.
With this, ray binning then accelerates the hybrid ray traverser tremendously because rays are fetched from the same pixels down the same mip map thereby having super efficient cache utilisation. If your ray gets stuck behind objects as you find in classic screen-space reflections, this system then promotes the ray to become a ray trace/world space ray and continue from the failure point. We also get quality wins here as decals and grass strands will now be in reflections.
We have optimised the denoiser as well so it runs faster and we are also working on optimisations for our compute passes and filters that run throughout the ray tracing implementation.
These are all optimizations in this patch and none of them include "turning things off" in fact I bolded where they mentioned quality gains.
There is a slight loss from the hybrid system but it shouldn't be noticeable.
They specifically state in the article that they cull past a certain number of rays in highly reflective scenes to not blow the ray budget. So if you're staring at a body of water it will actually lower image quality of the reflection.
The word "culling" has nothing to do with whether something is in view. It just means discarding in this case.
HeavyHemi
No way! Newer games push current GPU's when run at their max settings... when did that happen? Someone ought to create a meme... 'Can it play BF V?
