My combination of DP 1.4 → HDMI 2.1 → HDMI 2.0 Fiber-Optic → LG TV on other end of house didn’t quite pan out the way I had hoped, but…

4K 12-Bit RGB @ 60 Hz is working.

And it is glorious, compared to 4K 8-bit HDR :slight_smile: Most games don’t even have a framebuffer with enough color precision to use this signal correctly.

Off the top of my head, the only games that come to mind are Far Cry 5, and Final Fantasy XV. Everyone else cheaps out and uses 10-bit HDR.

Oh, and with SK’s Display menu, you can even override the system into doing this:

12-bit YCbCr 4:4:4, the NVCPL doesn’t even let you select that.

Lol, are we expected to play Fortnite to view the cooler from other angles?

What’s the perceivable difference between 12 bit and 10 bit? Don’t know if that’s a dumb question XD I’m assuming it just allows for more shades of colour.

The panel itself is 10-bit, so the difference is down to post-processing done by the TV in non-PC picture modes.

Less color banding if a game’s not doing a good job tonemapping its HDR image to your actual display device’s capabilities (which is basically all of them at the moment).

Did you also grab that DP 1.4 to HDMI 2.1 converter. :smiley: I assume you will have the 3090 in 2 weeks, so that won’t be a problem anymore. Plus G-sync as well.

Is there any advantage of using exclusive fullscreen vs. borderless + flipmodel ?

Talking about 10/12-bit, I have learned that the latest ReShade can force the framebuffer at 10 bit. In some DX9 games, this helps reduce banding as well, and it does work with SpecialK.

On DX11 SpecialK HDR is vastly superior though.

@Kaldaien will the new hdr options works with RDR2 in vulkan? It`s very bland the implementation

Absolutely. This is where Fullscreen Exclusive + Flip Model becomes an actual thing.

Flip Model is needed to run a DXGI game in “Advanced Color Mode” (HDR in other words), but borderless window mode constrains you to the pixel format and refresh rate of the DWM. Of course, 99.999% of games in existence are going to not bother with any of this stuff, they will just “turn HDR on” and offer refresh rate settings (if you are lucky), none will ever let you select color encoding.

That’s why NVCPL needs a bit of work. It doesn’t expose all of these color encodings that are actually possible to run the DWM in and by extension any HDR game you happen to run. You really need to be mindful of the color format the DWM is using, it’s not talked about enough.

I am profoundly bothered by the direction Microsoft has been going with UWP :-\

" Currently, only UWP apps can obtain the current SDR reference white level via AdvancedColorInfo.SdrWhiteLevelInNits . This API requires a CoreWindow ."

That would be great for regular old Win32 software and would actually remove a calibration step from Special K entirely as I could go by the Windows HDR/SDR balance settings you’re required to configure to run the DWM In HDR in the first place.

OMG Hype is real then lol.

I hope that’s 44k shares for $3.4 million, and not 44 shares for 3.4k xD

Just get one of these

If I were fabulously wealthy, there would not be a “Donate” button at the top of this website :slight_smile:

That said, my meager allotment of NVIDIA stock moved almost enough today to pay for a new GPU.

Well at least the waters bound to be clean.
(Though from what I remember reading somewhere if the water appears too clean it might also be quite hazardous from things that kill otherwise common plant life and such.)

Some of the places around here are now fairly well maintained though bigger efforts on cleaning up and purifying the lakes have done a pretty good job so less of a chance for metal, glass or other junk, sewage or the occasional body or chemical problem in the water. :smiley:

EDIT: Oh yeah the usual darker Nordic humor.
One of the lakes is within a larger military zone for a wide variety of field tests, used to be artillery and heavy armor but it’s mostly infantry training and a separate firing range with the area also shrunk down significantly from the 1980’s though many of the older fortifications were still around but since young people used them as hangouts many of these have since been concrete filled.

Secondary lake was next to the former asylum and mental hospital, still makes for a imposing sight still.

One of the bigger more popular lakes had urbanization and more houses so that’s the sewage problem but some changes and better infrastructure has lessened it considerably.

Still a problem with people dumping trash or sabotaging beach areas with glass bottles or metal shrapnel plus natural issues like algae bloom.

EDIT: Bunkers and some of the other fortifications are pretty nifty but I can understand why they are filled over and closed due to increasing popularity among some of the younger explorers or used as hangout spots.

Think it wasn’t more than a year or two ago someone got arrested for wandering around one of the active signal and radar sites somewhere in the country whereas these here are all abandoned.

Lmao, this is cute, didn’t even know tiny founders cards were a thing

And that’s surprising if a blower design actually works at this size.

AMD’s Nano variant of the Fury GPU though the 1050 might be a bit smaller still.

Lowest clocked yet highest binned Radeon Fury GPU chips due to the stricter voltage requirements, made for some variants using the Nano PCB and higher binned GPU chips for third party designs with the cooler over the PCB’s actual length. :smiley:

Pretty good too and a bit of a interesting choice for being a fairly high-end product from how I remember though lower clocked unless unlocked.

EDIT: Suppose blowing air everywhere is also a thing since yeah not sure the short length is optimal for how the blower design is meant with a back fan and heat transferred through the cooling plate and fins out the front end of the GPU.

Has to make the air a bit hotter at least plus a bit of air blown around the GPU itself not just transferred out when it’s these shorter designs.

EDIT: PCB Size would be easier with HBM type memory too but that’s costlier and there’s still the VRM’s and other circuitry the memory chips are still pretty close to the GPU most of the time but it opens up for some form factors when the GPU die also houses the VRAM bits directly.
(And some challenges for cooling and the complications like the memory connectivity to the GPU and all that wiring for the interposer.)

Oh yeah, i always forget the Nano and Fury cards were a thing - i just remember it as Polaris, then Vega.

Same as Vega it didn’t quite live up to expectations though it had less drawbacks than intended but the lack of primitive discard support and advancements that came with Polaris and it’s 500 series refresh especially saw the 580 start surpassing Fury in benchmarks. :slight_smile:

Vega had some good ideas too but something went wrong so it has silicon level hardware errors and issues making it impossible to leverage some of it’s features that did make it to implementation including the entire Next Gen Geometry path which would then be corrected for Navi. :slight_smile:

Not sure about launch GPU’s but there’s also been a bit of a lack on lower power 75w type cards not requiring external power beyond what the PCI Express can supply which also used to be more common.

Need to check but I think it’s mostly been NVIDIA although AMD has had a series of GPU’s now where they push the cards pretty heavily which increases the power draw total even if the architecture can actually be fairly efficiency in many cases including even Vega and Navi.

Potentially the Radeon VII too but this product varies heavily in how well binned the chip is down from 1.090 somewhere up to 1.2 default voltage.
(Manages things depending on what the hardware reports, Navi is also dynamic in a similar way but has a fixed set voltage maximum of 1.2v for all cards.)

EDIT: Well that and availability, Nano was the better possibly the best binned Fury type GPU chips due to needing a high performing but lower voltage amount possibly even above what Apple got for their Mac Pro AMD GPU lineup or what it’s called and then the consumer desktop products.

Was going to be a Vega Nano as well but AMD scrapped it and Sapphire got the PCB’s for their Pulse lineup but I think there was also at least one or two more cards based on the reference Vega Pulse PCB afterwards too.

EDIT: Basically AMD had some further plans for Nano but it appears those got shelved when Vega under performed and didn’t quite deliver as expected and then presumably a shift and some layoffs on AMD and the Radeon Technologies Group with a renewed focus on the Navi architecture and RDNA.

Splitting into CDNA for professional as a more workstation oriented branch for what GCN was.
(Instead of trying to make GCN work for gaming in addition to compute works which is what RDNA will be focusing on as I understand it.)
