Same but 1080 Ti? I hope the new cards aren't particularly good at bit coins so that I can get one

Here's all the known games that will support that cool new tech: I still maintain the best thing to do with any generation is wait for the x80ti launch, no matter which card you intend to buy at that point. Sure it feels like you're only relevant for half a generation, but you get over that by telling yourself that every generation before the x80ti is simply a paper launch and you should just wait.

You could make the same arguments for the Titan since its release but I get the feeling the lineup we've gotten used to is going to change

I thought ray tracing was supposed to be virtually impossible to do in realtime. Mind you, I read that around 10-15 years ago. Is it just the actual existence of raw computing power that's making it possible now?

It's making it possible to raytrace the stuff that benefits most from raytracing and then use machine learning/fuzzing to bullshit the rest.

Remedy posted their GDC slides breaking down that demo above and comparing it to their normal rasterizer: https://www.remedygames.com/experiments-with-directx-raytracing-in-remedys-northlight-engine/ warning: 858mb powerpoint lol eames posted:Does this mean DXR rendering will bring linear performance scaling with multiple GPUs? If someone were to build a purely raytraced engine, then yes it would be trivial to get linear scaling over an arbitrary number of GPUs. I doubt pure raytracing will be fast enough to ship in games any time soon though, the first round of DXR implementations will probably be hybrids (e.g. rasterized base pass + raytraced reflection pass) and have the usual problems with multiple GPUs. repiv fucked around with this message at 20:42 on Mar 19, 2018 |

For the olds with ancient aging bodies among us, can someone explain what ray-tracing brings to the gaming table that's different from what's going on now? Please explain as if you were talking to a three year old.

This is a good youtube explanation: https://www.youtube.com/watch?v=DtfEVO9Oc3U Basically raytracing is being able to go by a pixel-by-pixel basis to exactly identify what is "seen" by the monitor. It looks really good but its really computationally expensive. This DX12 implementation is likely a combination of things to do enough of it cheaply enough to be feasible in games.

I see. Anandtech's Slides mention "Ray Tracing for Gameworks" which includes Ray Traced Area Shadows, Glossy Reflections and Ambient Occlusion. They also mention that these effects done with RTX on Volta would be "integer multiples faster" than with DXR on older hardware (I assume that means software via compute units). Sounds nice but a bit Hairworks 2.0 to me.

Eletriarnation posted:Eh, I'm probably weird but I usually play my games on a 4k/60Hz screen and I just have a 1060. For newer games I often step down to 1080p, but emulators and anything indie/older than a year or two work great. As year-end treat for myself, I picked up an ASUS ROG PG279, and it is loving lovely. For me, it stems from a couple of aspects. Previously I could un-cap the frame-rate but then have tearing, and tearing is nails-down-a-chalkboard noticeable and intolreable to me. Screen-tearing pains me. Or I could lock to 60Hz (on my LG 27EA63V-P), but then have some juddering or pacing issues unless I ratcheted settings down sufficiently. With the hardware-sync, I get no tearing, and no need to worry about ensuring absolutely consistency of framerate. I get to crank everything the hell up, squeeze everything I can from my card (the 980ti seems to do alright at 1440p), and it's good times. To be sure, it was a meaty premium over a 27-inch, responsive monitor *without* G-Sync, but I found it very worthwhile, and pretty much the moment I fired the first game up on it, any fear of buyers remorse entirely dissipated. Hell, I'd get a second one (I have a dual-screen set-up), but my other monitor is fine for media and consoles (PS4, Switch, etc, through a HDMI switcher).

Honestly that first DXR example made by EA looked stunning, but I think it is way too early in the tech to say that it is obsoleting current gen hardware with the next gen. Considering the current DX12 adoption rates alone, I would not expect developers to be utilizing DXR for years yet (unless your that one indie dev who wants to make the next Myst who has all the time in the world to focus on A. puzzles and B. experimental graphics.) Microsoft also specifically stated that the API leaves pretty much all of the interpretation of the feature up to the hardware engineers, so even if next gen cards "support" DXR hardware acceleration you can bet that there will continue to be multiple iterations for years to come.

Dadbod Apocalypse posted:For the olds with ancient aging bodies among us, can someone explain what ray-tracing brings to the gaming table that's different from what's going on now? Raytracing actually models millions of rays of light leaving each source and reflecting from objects. This looks realistic, but is computationally infeasible for rendering complex scenes in realtime. In the field of cinema CGI, taking 30-60 minutes per frame is not uncommon. Realtime graphics like gaming use a bag of mathematical tricks to simulate this. It looks worse, but you can do it in real-time.

Dadbod Apocalypse posted:For the olds with ancient aging bodies among us, can someone explain what ray-tracing brings to the gaming table that's different from what's going on now?  The softening of the shadow here as it extends further out would be expensive to implement in current engines, for instance. In practice I think the most immediate benefit of path tracing is more accurate reflections, since current games use either a cubemap or some screen space effect, both of which can look pretty janky.

Well, except it works in reverse, doesn't it? It doesn't trace every ray, it traces from each pixel and says "What object will I hit and how does the light interface with it?" Basically, you go backwards and start with where the light ends up and only bother figuring out what happens to those light rays, not the ones that don't end up in the "eye".

eBay prices are coming down. $235 for a 1060 3 GB, $460 for a 1070. Still above MSRP but that's 25% lower than they were a month ago. If the dip in Bitcoin and Eth continues, and especially if it turns out NVIDIA has been stockpiling next-gen Turing/Ampere cards, prices are going to plunge pretty hard here.

I feel like raytracing could be extremely useful for VR content, and it could be done in real-time on games like Superhot which have Quake 2 level graphics by default. I've viewed static raytraced images on Gear VR and it really sells the realism when the lighting is so intricate.

Zero VGS posted:I feel like raytracing could be extremely useful for VR content, and it could be done in real-time on games like Superhot which have Quake 2 level graphics by default. It's a natural fit for VR because instead of rendering a normal rectangular image then applying VR distortion correction afterwards, which causes an uneven distribution of detail, a raytracer can just render the distorted image directly. Much cleaner. The hard part is hitting 90fps but I suppose you could dynamically adjust the sample count to hit that mark, increasing noise instead of dropping frames. repiv fucked around with this message at 01:29 on Mar 20, 2018 |

Perhaps a long shot, but is there anyone working at NVIDIA who’d entertain questions from someone with an offer? Glassdoor and such are helpful, but don’t always tell the whole story so I’m interested in soliciting as many opinions as I can. I have PMs if so.
