Adrenalin Enhancements Part 1: E-Sync, Chill, WattMan & FRTC

When Enhanced Sync was introduced in the mid-year Radeon Software Crimson ReLive Edition 17.7.2, AMD finally had an equivalent to NVIDIA’s Fast Sync and Adaptive V-Sync, a combination of technologies that aim to reduce the drawbacks of enabling V-Sync. At framerates above a monitors refresh rate, Enhanced Sync keeps the keeps the frame rate unlocked and displays the most recently completed frame to reduce V-Sync’s latency, or input lag. At framerates below the refresh rate Enhanced Sync simply disables V-Sync to reduce V-Sync stuttering.

With Adrenalin, Enhanced Sync is now supported for all GCN GPUs, as opposed to only Polaris and Vega based GPUs. And beyond that, Enhanced Sync now supports Vulkan applications, notebooks with dGPU-driven displays, multi-GPU (mGPU), and AMD Eyefinity. 

Moving onto Radeon Chill, a power saving feature that modulates framerates based on in-game movement, this now supports “countless” games, including ones powered by Vulkan. As far as “countless” goes, the only details disclosed were that this was accomplished via a generic Chill profile.

Radeon WattMan also received custom profile capability. Profiles can be saved, loaded, and shared.

These past three developments are arguably some of the most desired updates, at least according to AMD’s feature voting page: these changes were #1, #2, and #3 respectively of what users voted on most.

Lastly, FRTC now supports Vulkan as well, rounding out this first batch of ‘short and sweet’ Adrenalin improvements.

    I care about watts... Because although I live in a 1st world country... My electricity prices are trending towards 50' cents per KWH.

    With that... AMD ain't all bad as far as power consumption goes, VEGA for instance if you underclock and undervolt her, she can sip on the power... Still. I'll wait to upgrade from my Polaris card and hope Navi brings the goods next year.

    "People like you care about Watts like you live in a 3rd world country."

    Donald Trump is broadening his horizons it seems, no longer is he content with trolling twitter.

    Only idiots would not care about Watts. Less Watts -> less heat -> less than noise -> better cooling -> better overclocking.
    Only idiots would not want greater efficiency.

    Also, Nvidia offers a rendering software for like $300 a year called Nvidia IRAY.

    AND offer ProRenderer for FREE, and guess what? It works with Nvidia GPUs unlike Nvidia not working with AMD GPUs.

    That's the kind of future we get with Nvidia, all they care about is money. A real business with a good business model cares about the consumer as well.

    The consumer is free not to buy their products. Your name is ironic. Capitalism is simply don't steal and keep your word, the basic essence of free trade. "care" is an emotional concept, that's the sort of thing inferred by the customer, not implied by the seller. If NV is making pots, good, means they've found a market. Rule one of invention: identify a need. Reply

    "As for Vega, it's terrible in perf per W, perf per mm2 and much worse in perf per cost(note that cost and price are 2 different things). Vega 64 and 56 are a disaster for gaming and you are the one that lacks a clue, or objectivity."

    This just shows that you have never used one. I have 2 and they're both running within 200W* undervolted (Superposition can push this up to 250W due to the number of triangles it renders, but only if you raise the power limit). GTX 1080 is 180W, more if OC'd obviously.
    *165-212W in Wolfenstein 2 and Ashes of the Singularity, 4k60p. 1565MHz avg. @ 1.006-1.025v, 1100MHz HBM.

    If you want to brute force Vega, you obviously can with power limit increases and more voltage. I've found that that isn't worth it, unless you're going for outright performance or bragging rights in benches. Vega will easily pull over 300W (hit 306-326W in Superposition 4k optimized with auto voltages and +50% power limit), but it doesn't tend to gain a huge amount of performance. I'm more interested in its efficiency, and have been surprised by it. I'm not easily swayed by internet opinion though.

    "this is the beginning of the end for PC gaming" - you sound like some doomsday evangelist, the kind that is proven wrong repeatedly... every year.

    Your statements are two-part.
    a)something obvious that most can nod to
    b)absurd speculation to draw attention(probably a endorphin driven loop when you get replies)

    This site really needs an upvote system to weed out this sort of behavior.
