Remedy Shows The Preliminary Cost of NVIDIA RTX Ray Tracing Effects in Performance
Real time ray tracing won't be cheap. NVIDIA GeForce RTX 20 Series graphics cards are quite expensive, but even with that resources the cost to take advantage of this rendering technique will be high. We didn't know for sure what this cost would be, but the developers at Remedy have shown some preliminary results on that front. This company is working on Control, one of the first games with RTX support, and although they have not provided framerate numbers, what we do know is that the activation of ray tracing imposes a clear impact.
It does at least in these preliminary tests with its Northlight Engine. In an experimental scene with a wet marble floor and a lot of detailed furniture they were able to evaluate the cost of enabling RTX. There is a 9.2 ms performance overhead per frame in total: 2.3 ms to compute shadows; 4.4 ms to compute reflexions; and 2.5 ms for the global denoising lighting. These are not good news for those who enjoy games at 1080p60.
Remedy may be able to reduce that impact in the final version of its engine and in the game, but those 9.2 ms will clearly influence the framerate we can achieve. Playing at 30 fps requires 33 ms and playing at 60 fps requires 17 ms per frame. If we enable NVIDIA's RTX effects that would translate to a framerate of about 40 fps during the game with a 1920x1080 resolution on a GeForce RTX 2080 Ti. The result is excellent visually: clearer shadows and reflections that are independent of the camera and angle show up and give a photorealistic finish to the game, but the cost is high. Too much, maybe?

It will require Nvidia collaberation/bank-roll
Its going to be a "feature added" because making the game solely for RT is going to limit the targeted audience and potential income.
Indeed, that will make it doubly hard for Indie studios to have this feature in the early years, because they do only have a small team.
One just needs to watch all the dev diaries of Ninja Theory who put out Hellblade and see how much they had to be inventive and figure out how to pull things off with only 20 people and very little budget. I doubt they would have been able to implement RTX in all the scenes without adding another year.
sure nvidia did it, its not perfect yet and still could take 2+ or more years to get the 1080p 60FPS on 2070,2080, if the 2080ti can even handle 1080p60, if not then they have problems..\\\ and sure MASSIVE EFFORT, how about more like Nvidia has enough money for R&D and prob. still had enough to buy the Whitehouse or several states or something, when u have money to burn, literally!!!! u can do almost anything, AMD Doesn't have that and how DO U know or anyone that AMD isnt doing something for Ray Tracing there is also Path Tracing, just heard about it, but we dont know whats gonna happen NO ONE DOES OR EVER WILL THIS SHIT WILL BE UNDER EMBARGO UNTIL ITS NDA IS LIFTED, SO unless u work for Nvidia, AMD or intel ect. how will u know if these companies have plans for something or not... u DONT!!!!!!!!!!!
an oh.... "bringing photorealistic lighting, shading and reflections to the masses. " I think not, not when the RTX 20 series cards manly the 2080ti, is over 1000 bucks USD, thats not for the masses, maybe 20% of the worlds population that games can actualy buy that card>>>> i cant, i dont have a grand just to buy aGPU,,, i never will..
at 1200+ dollars each they want you to spend 2500 USD on just the gpus PLUS an expensive motherboard that support dual gpu PLUS an expensive CPU that have enough pci-e lanes
so yeah PC gaming has gone from 600-1000 to 5000 dollars in less than a year. Congratulations!
