[Eurogamer] Project Scorpio supports FreeSync and next-gen HDMI - Page 10

While they don't "need" more power, if they ever come out with a 4K Switch I'll buy one for sure. The aesthetics are fine and Nintendo has demonstrated their continued mastery of gameplay in a modern setting, all I really want from Nintendo above what they're providing now is more technical proficiency, make the next Zelda game run at 60fps, HDR, and 4K (using OLED on the Switch would make the system that much more appealing).
Or at least give me the option to spend an extra few hundred dollars to get that option.

Scorpio and PS4 Pro are a step in the right direction, hopefully next generation will be even more open about letting people choose their framerare and resolution.

I know it's a bit off topic, but THIS EXACTLY.

Z:BotW is breathtaking on the Wii U. I can't even imagine what Nintendo could do with a Scorpio/PS4Pro. It would be spectacular.

tl;dr it has no way to physically communicate with the AdaptiveSync controller.

In other words: Hardware DRM.

Woah... So this means if suddenly nvidia drops g-sync and start supporting free-sync, I would need to buy their newest gpu to be able to use with a free-sync monitor?

Yes, the biggest difference between G-Sync and FreeSync is what happens below 30 FPS, or the VRR window. G-Sync uses the on-board 768 MB of RAM to perform frame doubling, tripling, etc. AMD later implemented a similar feature called Low Framerate Compensation (LFC), but not all displays have it. Only a few of their higher end 1440P displays have it and none of the 4K displays I know of have it.

LFC is implemented on the GPU and have no panel dependency. They simply switch it off by default on panels where min FPS is lower than 40% max FPS because at that point it's close to pointless anyway. There is no hard coded FPS limit like 30.

AMD's original implementation (FSync ON, VSync OFF) was to push out new frames asap and give up sync when frame time goes out of range, which makes perfect sense because it gives you the lowest latency possible. But people cried "I'm seeing this tearing on lag spikes, make it like NVidia does", and AMD said "OK, I'll give you a little bit of buffering".

NVidia went in the opposite direction. The original GSync module setup forced frame duplication if there isn't at least one frame in the queue, resulting in a latency of one minimum frame time, but does ensure zero tearing. This isn't as good as it could be, but since everyone was comparing GSync to older VSync at that time and god has already told us the truth that the green team can't do anything wrong even when they set default prerender frame limit to 3, no one complained. In a later driver update they quietly switched to a more aggressive timing strategy. Both camps are doing it similarly now.

LFC support requires specific tuning on the panel scaler and it is dependent on the panel and not just GPU. There is a reason AMD maintains a list of FreeSync panels that support LFC.

Please go look it up on their website if you don't believe me.

No it doesn't require any monitor side tuning on the scaler or whatever. You will find on this website monitors that have been available and owned by people since well before LFC came about that work with LFC. It just requires 2X or greater max frame rate over minimum to work.

Which requires specific tuning to the scaler for that to happen!! It is why some FreeSync displays are 45-60 Hz VRR, others are 30-60 Hz, others 45-75 Hz, etc!!

It is why some panels support it and others don't, the manufacturer puts in the time to tune.

FreeSync isn't just software, but requires hardware as well. If that hardware isn't tuned right it won't work right or with all the features it can support. This is the difference in display quality across FreeSync offerings.

Do you work in an industry that spins a lot? They don't and never have to tune for LFC like you claimed in the post I quoted, any monitor with a wide enough range will LFC. Everything else you said is bleh.

Don't do this to yourself, don't engage. You're wasting your time.

It doesn't matter how hard you try to explain or how many times you repeat yourself, they're not here to talk, they're here to troll every single FreeSync thread into oblivion.

It sure looks that way given how he likes to twist things. Next he'll be claiming we're saying the same thing, just talking past each other.

I have no ghosting on any of my 4 freesync monitors. Got them because they cost almost the same as monitors without freesync... So why not lol.

Rane is short at 45hz-72hz. but hey I am above 60fps always. biggrin.gif

Oh and they only have HDMI ports.
