    You are correct, but that's quite stupid as well. Variable refresh rate is something that enhances the experience on every performance tiers, so it shouldn't have ever been a "premium feature" in the first place.

    This is not like having a large VRAM pool where only high end cards could make use of it, or raytracing hardware that would weigh too much on low/mid-end cards. Anyone can benefit from not going down directly to 30 FPS if the hardware can't maintain the framerate above 60FPS (or dealing with terrible tearing).

    I bet even the 15W 4C+GT2 Ice Lake is going to be great for gaming on UMPCs or surface-like tablets. 1TFLOPs GPU + >50GB/s from LPDDR4X + variable refresh rate will rock at 720p-900p.

    I have my doubts, remember "Hey mother board makers SLI is only possible if you buy a controller chip from us and put it on your boards"
    everyone (apart from asus) said "Er I think we'll pass" and as if by magic Nvidia engineers suddenly discovered sli would work without the chip possibly the same magic that put a " dont disable sli on boards that manufacturers have paid Nvidia money whitelist" in their drivers.

    Samsung C32HG70 & GTX 1060:
    - Works properly with "Ultimate Engine" FreeSync 2 mode, not so much with "Standard Engine" (Hz is variable in Standard Engine too but seems to be stuck 99% of time @ 13x-144Hz) ((Ultimate Engine VRR range is 48 - 144 Hz, Standard is 90 - 144 Hz I think))
    - Doubles/Triples(/even quadruples I think) Hz whenever possible (like 40 and 60 FPS both run at 120 Hz)
    - Some flickering in certain situations (so far noticed in Overwatch borderless windowed mode, works fine in fullscreen, pubg works fine both borderless windowed & fullscreen)
    - Works with HDR (tested with Hellblade: Senua's Sacrifice)

    Totally different beasts, the level of variables required here are too many (HDR1000 + 120Hz + VRR (1-120Hz range) + Full Array Local Dimming + variable overdrive).

    In your CF example, multi GPUs has already been shown to work without a specific controller, and it was obvious that NVIDIA was making a marketing stunt. This is not the case with GSync HDR. The new complex GSync HDR module already costs 500$ alone to make, a complexity that is required to handle all those variables. Also there are no VRR monitors supporting those features without a module. Monitor manufacturers are going to need to beef up their controllers if they wish to offer the same level of feature support.

    Yeah I believe only Pascal and later supports Adaptive Sync.

    According to Hardware Unboxed who tested a bunch of their Adaptive Sync monitors (all worked flawlessly), the Nvidia implementation doesn't support HDMI. VRR with Adaptive Sync monitors is only available over DisplayPort. AMD does support VRR over HDMI.

    Yeah, I read HDMI support wasn't going to make it the first round though may be added in future drivers.

    Hmm so that would make it more expensive to produce than most (if not all?) the gpus than nVidia sells to gamers. Source for this?

    It's an FPGA from Altera (Intel), it's called Arria 10 GX 480, and comes with 3GB of DDR4-2400 RAM. It's sold separately online for 2000$. But PCPer estimates the cost on NVIDIA to be around 500$.

    Well at least an FPGA can be replaced by ASICs further into the lifetime of this countroller, driving prices down (one could only hope)

    Here's hoping to a decent enough Freesync HDR implementation so we won't be tempted into buying any of these

    Considering we never got ASICs from previous G-Sync versions, I wouldn't be holding my breath
    We already have it and have had it for quite some time, it's called FreeSync 2 HDR. If something isn't decent it's G-Sync Ultimate or whatever the HDR-version is now called where you need to shove in 2-3 good gaming pc's worth of money just for a display and are coming a year later than you were supposed to

    I wouldn't either. The volumes for these monitors will be lower still compared the original G-Sync


    Maybe my phrasing was wrong. I know of FreeSync 2 HDR. I didn't follow how it actually performs though.
    And for now, I don't even care. I'd buy into HDR tech once it matures more.. in 2 years maybe. For that hypothetical extra 500 $, G-Sync HDR better be miles ahead of their competition by then. Also, wouldn't hold my breath.

    When held to the standards of the top features in a monitor, it's called barely there. Till this moment there is barely any FreeSync 2 monitor with HDR1000 + LFC, let alone the other features (Full Array Local Dimming + 144Hz + variable overdrive).

    I am all for a cheap monitor with those features, I would buy it in a heart beat, but the fact is: they are not available outside of these ridiculously expensive GSync panels. So I am to wait till further notice.

    Well, currently there's four DisplayHDR 1000 certified products, one of them is FreeSync and rest G-Sync. Granted, features don't match really as the FreeSync one is only 60 - 80 Hz and has less backlight zones, but it's also priced at half the g-sync monitors prices while being a lot bigger (Philips 43" under $1k, Asus / Acer 27"'s around $2k (and there's the HP 65" but that thing is priced at $5k)

    Works fine here:

    [​IMG]

    Gsync + Freesync displays work together without issues. My 4K 60hz monitor can do 32-60 hz range without issues, freaks out if I set it to 30-60 (can't handle LFC).

    Somewhat related to this you can only have one freesync/adaptive-sync display with NVIDIA, so if you're using more than one freesync capable display you have to pick which display to enable it on

    As an update after couple days more experience:
    - Overwatch now shows black bar artifacts + blinking always in borderless windowed
    - Today alone got 2 or 3 times random mode switch on display while playing Overwatch fullscreen, returned to normal each time
    - Sometimes when starting up Overwatch (in fullscreen mode) the display stays in HDR mode, have to alt+tab to desktop and back to get to SDR mode (usually works on 1st try)
    - Sometimes when alt+tabbing to fullscreen Overwatch the display stays black and complains about "unoptimal resolution/refresh rate", only solution is alt+enter to windowed mode and manually setting the game back to fullscreen from options (alt+enter back to fullscreen doesn't work)

    Have you tried fullscreen windowed?

    borderless windowed = fullscreen windowed
