2K and 4K refer to horizontal resolutions (2048 and 4096) because they originate in film scanning: it makes more sense to standardize scanning resolutions by the width of the film.

My AMD card self-reports at ~35W idle (at 300 MHz too, so it's probably mostly VRAM?). I've read that having two monitors of differing resolution increases the idle power significantly, no idea how true this is though.

Zedsdeadbaby posted: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? 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.

orcane posted:The human eye is not a camera though, so DoF effects and motion blur are 100% about games trying to be movies. So yeah, art. There are good reasons to have motion blur in video that are unrelated to movies: it's arguably less correct to treat each pixel as a point sample in the temporal dimension, and conventional 180 degree shutter angle is a good compromise between sharpness and coverage. Movies have the option to reduce motion blur too, but they don't because less blur looks unnaturally jerky.

That depends on what's meant by foreseeable I think? The next gen of consoles are expected to release in 2020, and I can imagine games needing more than a 1060 at 1080p60 after that (if you want all the fancy new effects and stuff)

Partial Octopus posted:So it seems like most 3-fan cards are in the 300mm range. My case can fit a max of around a 286mm card. Will I lose much performance if I go with a shorter card with fewer fans? Or is it just going to be a bit louder? Is it worth changing my case to just accommodate larger cards? There are some outliers like MSI's Armor cooler where they tried to save too much money on the heatsink, or small form factor cards that intentionally give up performance to fit in a smaller size.

It's kinda telling how many of the games demoed so far do only one effect at a time. Shadows in Tomb Raider, reflections in Battlefield, diffuse GI for Metro. Control looks likes it uses all of the above at once, though. I'm guessing it's even less performant in real time.

Quake 3 must be the earliest example of this, it had a console command to turn down texture resolution to basically nothing... which became standard in competitive play.

Zero VGS posted:My general impression was that "per transistor cost may increase" means in practice that a 2080 chip costs Nvidia $32 instead of $30 to manufacture, or something to that effect. Would the chip wholesale price difference of a couple bucks really scale exponentially to the MSRP? I would think MSRP is entirely based on what the market will bear and how much the competition is undercutting you. https://semiengineering.com/big-trouble-at-3nm/ - this article suggests that design costs alone are expected to increase by the hundreds of millions per chip: quote:Design costs are also a problem. Generally, IC design costs have jumped from $51.3 million for a 28nm planar device to $297.8 million for a 7nm chip and $542.2 million for 5nm, according to IBS. But at 3nm, IC design costs range from a staggering $500 million to $1.5 billion, according to IBS. The $1.5 billion figure involves a complex GPU at Nvidia.

AVeryLargeRadish posted:What you outlined is reasonable, but it's also not what I was complaining about. I'm seeing people say that Nvidia should not release cards with new tech unless there is software on the market that can use that new tech, to me at least that is ridiculous, someone has to take the first step and hardware makers are the ones that make the most sense for that. Like, nobody releases game consoles with zero launch games for the same reason.

AVeryLargeRadish posted:Yes, it is an unreasonable expectation on the PC. Consoles are completely different, you can't play a console game at all without the console, you're basically saying that developers should put resources into features that might be used at some point in the future and no dev in their right mind will do that when there are other things they could put their resources towards that see immediate benefit now. Nvidia just decided to launch the cards before a single implementation was ready.

Zero VGS posted:It definitely smears stuff in some of those shots. In motion it does seem hard to notice. However there's sustained shots in that video where it's the same or even a frame or two slower than TAA, so while much faster on average, it's not exactly consistent. I would like to see a comparison video like that, but showing DLSS, TAA, and no aliasing at all, so I can see how accurate they're both getting to the reference material.

K8.0 posted:Real-time TAA still always looks like dogshit, which is specifically why Nvidia chooses it as a comparison point. When we can compare DLSS to non-TAA images, then we'll see how it actually looks, and whether it makes 4k monitors a worthwhile purchase when worthwhile ones come out, or whether it's better to stick with 1440.

It's worth pointing out that PSNR is not necessarily an effective way to judge encoding quality across different implementations. x264 contains a few optimizations that worsen PSNR and SSIM but help a lot in improving perceptual quality.

I run the latest for a few hours (sometimes it crashes/errors when other stuff doesn't), which I can't imagine to be that much more damaging than running "normal" 100% loads with the same overclock for hours at a time over years.

That single fan doesn't look any bigger than the dual fans though, it's just a smaller heatsink to save costs and for small form factor builds. And heatsink surface area is a more important factor.

Digital Foundry also had a weird outlier where the 5700 and 5700 really underperformed at 1080p and 4K in Metro Exodus (but not 1440p): https://www.eurogamer.net/articles/digitalfoundry-2019-amd-radeon-rx-5700-rx-5700-xt-review-head-to-head-with-nvidia-super?page=5 I'd guess this is something fixable in a driver update.

The other disadvantage to the probe approach is that the resolution of the GI is limited by the density of the probes. The per-pixel approach has more refined higher frequency detail, so the probes are more reliant on screen space AO to make up for it. Still a pretty good trade-off if your main goal is to capture the general feel of the lighting in a space (and no worse than current baked probes).

Zotix posted:How much better at 1440p is a 2070 Super than a 1070GTX? I know we are basically talking 2+ generations of video cards, but I'm building an entirely new rig with a 3900x in it, and I was going to carry over my 1070 for a year until the next gen is fully released. However, I'm not sure of the performance I'll see on my new rig with the 1070. I'm upgrading from a 3570k to a 3900x, so I'm assuming I'll have some performance increase.

Taima posted:Yeah definitely. What’s the deal with that? It was also sometimes like an overexposed photo. The formats are futureproofed to the point that they specify much wider gamuts and higher peak brightnesses than any consumer display is capable of, so the display itself has to do an additional tone mapping operation to make it look acceptable. And I assume HDR monitors are not as good at this as TVs are if they're doing anything at all. Llamadeus fucked around with this message at 17:28 on Dec 10, 2019 |

"PS5 = 5500" is beyond lowballing it though, the current Xbox One X already has 5500 level perfomance and the fanboys are already mildly disappointed by the leaked 36 CU number.
