By now I have actually

No idea what's everyone griping about

Seems like a good product, just on the expensive side

I think for 50 bucks no one would complain
Or if the AA would be even better
At least you can reuse the cable for a few years/consoles/GPU's

But I think it's missing HDR, right?

I even had to agree that in tomb raider the mcable had a better AA than the one in-game
well the one Linus choose anyway, no idea if that really is the mode basically everyone uses

I kinda figured you might have watched it in the 8 1/2 hours between your comment and mine, but wanted to make sure.... Hehehe.... I'm thinking of getting a couple (not for $100+ though) for my girl's PS3 and Wii U, seems like they'd actually become tolerable for me to watch more, or even potentially play on. biggrin.gif

No mention of HDR, one way or the other, from what I've seen.

Who knows.... It definitely seems like an interesting piece of tech though.... There'll be other reviews, and if the consensus stays the same, then I'll probably end up with a couple.

I'm not sure MLAA was the first post-processing AA to be implemented, but there are many forms in use currently, and they are very common because of how poorly MSAA is supported in post-DX9 titles and how expensive SSAA is in terms of performance.

Generally, I'm tolerant of the trade-offs of post processing AA and even though performance costs are low, it's not free. So, if the cable could do it for me, without unacceptable side effects, I'd be willing to pay to shift the work there, and get my 3-5% performance boost in the titles that could use it.

I just got my hands on one of these yesterday (the latest version of the gamer edition) and would like to share some information as aside from an LTT video and the PC perspective post, there is not much to go by.

The cable is clearly introducing a kind of post-processing anti-aliasing which is objectively more effective than FXAA, MLAA, or SMAA (including reshade); interestingly it has no issues applying this AA (CXAA they call it, for "contextual") to game's existing AA, whether it is temporal, MSAA, or FXAA. In fact, it did a decent job cleaning up the missed edges and "noise" introduced by FXAA, temporal AA, and MSAA x2 in the console games I was testing. As someone who regularly uses reshade in most of my PC games that allow it, the method used by the cable has no real effect on text, which is often garbled by both SMAA and FXAA since they try and anti-alias text which has no aliasing, thus actually introducing it.

It is also applying a kind of blur filter independent of upscaling which has the side effect of making some textures have a kind of water-color look to them, the closest example being the noise reduction algorithm waifu2x uses. This may be what allows text and fine-detail images to look so clean despite the AA it is using (or perhaps the CXAA can detect text or something, I am not sure)

A sharpening filter is added likely to combat the inherent blur caused by post-process AA and the additional blur filter, and it does introduce slight halos around high-contrast transitions, such as tree leaves against a sky.

There are some artificial color adjustments done for color saturation and contrast, and perhaps a pseudo HDR attempt.

It has no issues working with DRS in games like Nioh, which is quite notorious for it, but since the upscaling is already being done by the console, the chip in the cable is not able to perform its own upscaling so the results are lackluster.

The integrated upscaler works far better than the ones in the 360, PS3, PS4, and X1, as well as the one integrated into my XL2430T monitor. I do not have an ultra high-end TV to test the scaler against sadly. My main issue with the scaler would be while it does work and provides substantial AA to 720P games, it introduces quite a lot of blurring in the process in addition to the aforementioned water-color effect.

Whether it is intentional or not, it does seem to do a kind of color-correction as it did an amazing job cleaning up Bloodborne, which it notorious for its near non-existent AA, noisy environment, and overdone chromatic aberration effect. It actually removed most of the chromatic aberration and made the game look good instead of retinal cancer.

Film-grain seems to be largely unaffected. Testing The Order 1886, it seems to have reduced it a bit, but this is likely just a side-effect of the blur filter it uses.

There is indeed no noticeable input latency as reported by the article and video.

Ultimately, it does a great job cleaning up 1080p titles, but the amount of blur it introduces in anything below that will likely be a bit too much for some, though much of this could possibly be compensated for on a TV or monitor with a high sharpness setting available.

Linus touched on it only a small amount in his video with what looked to be native 1080p rendering, but the sharpening filter seems to be the strongest when it is not upscaling sub-native content, I would be quite interested to see what two cables in series would do upscaling 360 or PS3 content, with the second cable mainly being used to apply additional sharpening to the already upscaled image.

I do not own any kind of image capture devices, but here is a screenshot from Bloodborne, which is probably the best example game I have.

I highlighted some of the "features" the cable provides

F6tBRNC.png

This is what it normally looks like

GRSfGnS.png

Both of these were taken on the same monitor with the same settings and the PS4 Pro outputting at 1080P on a native 1080P display.

I forgot to mention in my last post, but the cable appears to override the scaler built into your monitor/TV. My BenQ XL2430T has some pretty advanced scaling features and all of them are disabled aside from aspect ratio control. It simply puts out a 1080P signal regardless of the input resolution, though since I do not have a 4K display yet I am not 100% sure what it does in that scenario.

Wow that chromatic abberation is out of control. Pretty impressive for it to almost completely fix it. Thanks for the side by side. Its fantastic!
post #79 of 92
How exactly does this thing work? Is it possible for it to somehow actually apply genuine post processing AA on each frame? I could see a CMAA applying device being useful, not sure about how much it changed the color and sharpness though. And the fact that it apparently only works when the resolution matches on both ends

It has a powered (with USB) processing chip on one end of the cable--yes! a cable that only works one way!--that performs post-processing per frame similar to how reshade or sweetfx works on PC.

From the hours I have spent with it there is no extra input latency, as demonstrated by LTT and PC Per, nor is their any kind of motion blur or other strange artifacts introduced by the processing, whether the game is 30fps, 60fps, or variable. The cable seems to be locked at putting out a 1080p signal (maybe 4K if it detects it, I cannot confirm). I have tried it with my 360, ps3, ps4, and x1s and it simply puts out a 1080p signal regardless of what I set the consoles to. Getting it to work on PC is a bit finicky, though.
