It is indeed a 4K video, but one thing should be pointed out, the actual rendered scene has black horizontal bars on the top and bottom of the video, making it only around 3840x1645, which is ~24% less load than 4K (going from roughly 8.3 megapixels to 6.3). Still much better than 1440p (~3.7 megapixels), but it should nonetheless be noted.

And this is why, as of late, AAA titles using gimmicks like this lack any real substance or depth to them. It's a constant arms race to see who can make the most realistic looking puddle of water (Even if it means a drop from 144FPS to 40FPS)

Tomb Raider and BF5 come to mind...I've always been curious to know how much extra time is needed to add pointless gimmicks like this when games/titles are in development.

Plasma (Gaming/Multimedia) (Windows 10 PRO):
Ryzen 1600 OC'd @ 4.0Ghz [AIR] ||| 8GB ADATA DDR4-2666 APG "GAMMIX" ||| 750W Antec PSU ||| Gigabyte GTX 1060 6GB ||| 240GB Sandisk SSD

PlasmaNix (Linux Workstation) (Lubuntu 18.04 LTS):
Athlon II X2 @ 3.0Ghz [STOCK / AIR] ||| 16GB Kingston HyperX DDR3-1600 ||| 500W Antec PSU ||| 74GB RAPTOR HDD ||| Adaptec CERC 1TB RAID1

To get the opensource PhysX to be capable of GPU acceleration on an AMD GPU would require, at a minimum, the game be built w/the opensource PhysX GPU accelerated libraries and that might not be enough because it might be that AMD's drivers have to support PhysX GPU acceleration.

Well, the point of RTX (and most nVidia proprietary API's) is that it's easier to implement than something built from the ground up for a specific application or open standards. So, in that regard, it's saving dev time.

You can make the argument that not implementing raytracing is faster than doing it, but I don't consider the next step in graphical fidelity a "gimmick".

A dedicated physx card, let's say a 1080, and an AMD gpu in the same system, nvidia will disable physx on the gpu all together, even though the nvidia gpu would be doing the work. They put that in after it was proven that it works just fine having an amd gpu as the primary and a dedicated nvidia physx card. I have spare nvidia cards that could be put to use if nvidia weren't so hostile to the consumer.

imma gonna necro this for an update:

Crytek discusses Ray Tracing within CryEngine - Works on an RX Vega 56

Quote:
Earlier this year, Crytek revealed their "Neon Noir" tech demo, which showcased real-time ray tracing on non-RTX hardware, showing the company's API/Hardware agnostic solution for real-time raytraced reflections.

To say that this demo was impressive is an understatement, utilising an AMD RX Vega 56 graphics card to deliver ray-traced graphics within CryEngine, without the need for specialised ray tracing components, such as the Nvidia RTX series.

Crytek has now shed some light on their pre-GDC tech demo, confirming that it ran at 1080p 30FPS on AMD's RX Vega 56 when reflections ran at their full resolution. When reflections are running in half resolution mode, the demo runs at 40+ FPS at 1440p on the same graphics card, and this is without the benefits that could be offered by Vulkan or DirectX 12.
Quote:
Even while we were working on the demo, the ray tracing implementation improved a lot. Initially, the quality of the reflections wasn’t great and probably wouldn’t have held up considering the scene we created. However, while we built the scene, the team did an amazing job improving the reflections. The lighting in the reflections is now taken from the same cubemaps that light all the non-ray tracing pixels in the scene, lights and particles are working in reflections, and the overall visual quality of the reflections has improved significantly. The quality of the reflections is not yet on par with the renderer’s quality, but we made significant progress towards that during the last couple of weeks. While we worked on the demo, our rendering engineers also managed to add extra features like multiple bounces, and basic ray-traced refractions, which we tried our best to incorporate into the scene.

Performance has been improved throughout the entire process, allowing us to use more triangles for dynamic objects. At this stage, our ray-traced reflections are holding up well enough to present them as an experimental feature.

This is the interesting part for me:
Quote:
However, RTX will allow the effects to run at a higher resolution. At the moment on GTX 1080, we usually compute reflections and refractions at half-screen resolution. RTX will probably allow full-screen 4k resolution. It will also help us to have more dynamic elements in the scene, whereas currently, we have some limitations. Broadly speaking, RTX will not allow new features in CRYENGINE, but it will enable better performance and more details.
Can we please have some decent raytracing games already?

No need to upgrade, get fleeced and worry on whether you can still play your games down the road. That console will play 1440p 144Hz no problem let alone 1080p 60Hz at over 100+fps which 90% of the people own anyway.

Heck, I'll be tempted at that point and the PC Master Race will be over.

too black & white.

the space will merge into one monster. Home entertainment box with KB+M, and the ability to also stream in games. Only two of those features don't exist now, baked in KBM support, & streaming games.

also... technically... it's the console that died, since the modern consoles are now just laptops in a box, using identical hardware to PCs with special API.

Also, I fully expect MS & Sony to further diversify the line up, so that you've got the $500 box, and the $1000 box. At least, the only way we're gonna get any sorta quality 4K experience outta the next console is if it costs $1,000...

I mean it's been almost a decade since Keplar, PS4, and XB1 came out. The next round of consoles only means more good things for everyone. There's almost zero reason for AMD & NV to release products with massive leaps in performance and progress when there's nothing compelling them to do so. Console updates fix that issue for a short period of time.

I'd love to see what Sony, MS and Nintendo can offer with a heavily subsidized $ 1000 console.

Kinda true though and IMO eventually, phones will be good enough for the majority of gaming.. also remote computing.

Tbh, not sure what else mainstream gaming can offer other than mostly prettier games. It's mostly gonna be a mishmashpolish of already existing mechanics. Maybe better VR integration for the masses? I'll still enjoy them regardless.

I also think that we're currently hitting close to a wall and there are several articles about how tech improvements are getting slower and slower, something about physical limits. That's one of the big reasons why we're not getting "leaps and bounds" yearly anymore from almost all big techs like Intel, NV, AMD, etc. If this keeps up, consoles can have a more lasting power compared to previous gens.

A next gen console with something like 8 zen 2 cores, 24gb ram, SSD/new caching system for consoles will be the biggest reason PC will get bigger games as consoles raises the standards for majority of big game development while bottom mainstream development will be prioritized for mobile (future pubg, fortnite, mc, etc.). For some reason mainstream pc gaming might get stuck in between, falling more niche but who knows. PC gaming is apparently rising in China but I think mobile will still outpace it.

XB1X might seem to already punch way above its weight at $ 399 (frequent sale pricing in 2018). Next gen consoles at $ 499 might demolish majority of PC's attractive mainstream builds as far as graphics settings goes (and with diminishing returns in visuals: check DF video on "is ultra worth it?").

There's already KBM support for consoles but not if that properly works. Wonder if MS pushes this hard next gen. MS seem more willing than ever to integrate Xbox and PC.

For end consumers, plenty to wiggle in since a lot of the wanted features at certain pricepoints are subjective.
