Remedy, one of the companies that will implement real-time ray tracing effects in its upcoming title, Control, has revealed the performance overhead for the RTX effects in its Northlight Engine. According to the team, RTX effects require an additional of 9.2ms per frame.
Unfortunately Remedy did not reveal any framerate numbers, though it did reveal the additional computational power that is needed for specific effects like Global Illumination, reflections and de-noising.
As Golem reported, contact and sun shadows – calculated with two beams per pixel and with also including noise rejection – require 2.3ms per frame and the reflections require 4.4 ms per frame. As for the Global denoising lighting, it requires an additional 2.5ms. As such, we are basically looking at a 9.2ms performance overhead for the real-time ray tracing effects that Remedy will implement in – most likely – Control.
As pointed out, these are early numbers and Remedy may be able to reduce this overhead by tweaking the RTX effects. Now in case you did not know, 30fps require 33ms and 60fps require 17ms per frame. As such, for Remedy’s games that already run at 60fps we are basically looking at an overall performance of 26ms per frame when real-time ray tracing effects are enabled. This could translate to around 40fps, though do note that Remedy is using real-time ray tracing for very specific effects. As such, you cannot really use these numbers to estimate the performance overhead for other titles like Shadow of the Tomb Raider or Metro Exodus, or for games powered by Northlight that use RTX for completely different graphical effects.
Still, we believe that this is interesting and may give you an idea of the raw power required to run real-time ray tracing effects in modern games!

they must mean control, dunno where they got QB from
Fixed, obviously it’s Control
They’re adapting Janet Jackson songs into video games now. There’s no originality anymore.
I’m not falling for that trickery again
I used to know a girl named Trickery and I kept falling for her.
Damn, but please don’t fall…../s
Hmmm….
Glad Im moving to AMD, so I dont have to deal with closed source trash technology that takes performance out of games.
Lmfao this is the funniest thing I’ve read all day
Are you stoned ? Literally every new tech has to go through this. Global illumination, Volumetric lighting, Tesselation and so on. And 1. You can still turn it off. 2. Who cares if it’s « closed » source. Do you really think if AMD was in the same situation they would share all their R&D with the world for free ? They’ve been in a bad spot for years now ever since the mantle debacle and they gotta play nice otherwise they got nothing to show AT ALL. At least NV is pushing tech.
Honestly 9 Ms is pretty good for raytracing. That’s about as much as shadow prepass and stenciling so really not bad given the massive boost in image quality.
Interesting find, and a pretty good article, @JOHN…Keep up the good work ! 😀

JK is a confirmed TROLL. Lol. Created a new alt account to bash others. 2 abusive comments in a row.
A pity this website has no moderation whatsoever, and thanks to john giving us an “unrestrained Policy”.
Triggered…! Proves my point. What a sore loser who can only block other members, lol.
Well, if the base game runs like garbage like Quantum Break, there will absolutely be no justifying that extra 9.2ms. But, if they pull a miracle and it runs at, say 90 fps before RTX, then good to go.
I dont think it work’s like that. You see, RTX cores are separate cores and can bottleneck standard performance even if you will see more extreme numbers, even like 1000 fps. Let’s say CUDA cores performance can be like 1000 fps, while RTX effects can drag it down to lest say 40-60 because that’s how fast (or should I say slow) RTX cores will be. But in the future when RTX cores will be much faster it should not tank CUDA cores performance that much.
You know, that’s a good point. RTX isn’t a post process, it’s part of the pipeline. So you’re absolutely right. It could very well be a bottlenecking situation here.
It should be the same thing like pairing extremely fast GPU with slow CPU, so for example you can have high end GPU, but if you still use core 2 duo new games will not run very well because of CPU bottleneck. RTX cores are like seperate procesor, and testers like John will probably have to look separately for possible CPU, GPU, and RTX botllenecks.
RTX cores performance is probably barely enough for 60fps in 1080p, yet alone 1440p, or 4K, BUT I hope RTX games will offer some performance tweaks, because RTX effects rendered in 1080p should still look good even in higher resolutions (shadows and reflections in current games are also not rendered in 4K)
LOL.
Or you know, Quantum Break is a tech marvel with the best implementation of global illumination and real time reflections on the market so far and TONS of volumetric lightning, before Ray Tracing.
ha ha! Oh! You got me. ha ha.
Oh, wait, you’re serious?
That game looks like hot garbage at it’s stuttering 720p upscale, jittery shadows, inconsistent texturing, and in your face post processing that can’t be disabled. The entire game is noise.
I agree, but forgot to mention washed out colors 🙂
But that would add up to less than 60 fps. 90 fps = over 10 ms per frame. Add 9.2 ms and you get 20 ms total or worse. That’s 50 fps and not even stable 50 fps but wonky, stuttering modern game 50 fps.
MS windows 10 with raytracing update is up, and still no RTX patches for even single game. How Nv expect people to buy their RTX cards without actual games supporting RTX, DLSS or new shading methods?
They can’t even even fix HDR in Win 10.
Please tell me if HDR is still broken in Win 10 1809 ? thanks
That’s bad marketing. True.
Nvidia could make dedicated RTX cards for the enthusiasts to use with GTX cards in an sli configuration. Putting small number of RT cores next to a lot of SM cores and expecting them to work together doesnt make sense
What next a dedicated physx card?
Still too soon. RIP Ageia.
That’s a big hit if targeting 60fps. Well worth the visual advance thought I think!
Nobody paying $1200 for a graphics card is going to want to game at 40 fps.
They will if they want a cinematic gaming experience. And by that I mean closer to 24fps.
30 fps is the minimum for a cinematic experience. Anything lower is better. I personally play games if possible on 10 fps. Its absolutely amazing and inredibly cinematic imo.
People who care about image quality will and did, 2080 Ti is hard to find less than $1600.
Adult films should employ ray tracing. Maybe then the stories would be better.
To be honest in adult movies the story is less important than the ray traced actresses and actress

non of this indicates anything
this is pre-alpha testing
on MAY 2018, i have bought msi gtx 1080 8gb in my country, for about USD 770…. ^^
You got ripped off.
did u know, that in my country….. right now, the price of MSI RTX 2080 8GB GAMING X TRIO is about USD 1200 ?? ^^
Ha! beat this…. Last week I saw a new 1080-ti Trio that was $1900 (CDN) …same price as the same model of 2080ti . This current market from top to bottom is f*cking preposterous. Im out until things settle.
where is that ?? ^^
Canada newegg.
