    Does this driver support the VRR (variable refresh rate) option under Windows' Settings > Display > Advanced Graphics like the v435.27 ones did?

    It would have said this was a newer build of the v435.27 driver but if it's lacking the Latency options then it possibly isn't but a different branch completely.

    Kind of annoying that NVIDIA don't do release notes for these drivers. IMO, any driver from NVIDIA, whether alpha, beta, official or whatever, *should* have some release notes so people are aware of what is new, what is fixed and what has been changed.

    Combination of pre-rendered frames and multi-threaded rendering optimizations into a singular slider setting.
    Off, low and high I think it was.

    Off - 3 pre-rendered frames, MTR on.
    Low - 1 pre-rendered frame, MTR on. (Can reduce input latency, might lead to some hitching though.)
    High - 1 pre-rendered frame, MTR off. (Not entirely sure why multi-threaded rendering optimizations are forced off, I assume it is related to latency in some way but it could affect performance a bit having it disabled.)

    EDIT: From memory there's a post on the GeForce.com forums with a better overview of what each respective level actually did and I would assume later drivers then worked this into the tooltip for the options in NVCP itself for clarification. :)
    (So that you don't just push this to the maximum thinking it just reduces latency without affecting anything else when it's a combination of two existing settings.)

    EDIT: Far as hitching and stuttering goes I would assume as long as the CPU can handle the workload from just a single frame being pre-rendered and queued up this isn't going to be too problematic but it might vary from game to game depending on CPU and GPU workload and factors such as the game or game engine and how it works and possibly limitations depending on API used if that factors in at all.
    (Multi-threaded rendering optimization I expect won't do much for D3D9 and I am not sure how much of this can be overriden from the driver for D3D12 and Vulkan or if that has explicit control.)

    Thanks for clarifying. Sounded like snake oil in the first place, if it "just" combines settings it's nothing new I guess. And I can confirm that MTR doesn't really shine on dx9, it's actually counter productive afaik.

    I believe the intent was to make it simpler or easier for the end user but the wording and explanation at least in the first driver when it appeared wasn't entirely clear though since a NVIDIA spokesperson clarified what each respective level of it did I would expect the tooltip and later driver releases to make it more clear on what this changes without having to look it up. :)

    As a part power user myself though I prefer separate options and more fine control though perhaps utilities or more in-depth tweaking still works instead of off or low and then high just sounds like it would be best avoided other than some specific profile cases or as a test.
    From how it sounds like at least, doesn't seem like it's very beneficial to turn multi-threaded rendering off like this and the driver probably manages the setting on it's own when it's not forced into a specific behavior for known games and profiles.

    EDIT: But maybe that's best for the option overall, keep it unchanged for the global settings and modify it on a per profile basis as needed or what "feels" best though testing and comparison might be ideal but also takes a bit more time.

    Just did a few rounds of BFV seems a very good driver on my system, solid 100 fps (monitor refresh rate) and smooth.

    I tried the nightly build now, but it was the same for me as before. In full screen the videos are super laggy.

    In firefox type: about:config

    media.gpu-process-decoder

    layers.gpu-process.enabled

    Turning both of these options to false fixes the problem tho :)

    I tried 'Lowest latency' option on the prior 435 drivers and got great results with latency; definitely felt more responsive. I was conscious of input lag being present prior with the older drivers. I however couldn't confirm if it was placebo or simply bad prior settings; went back to 431.68 to try pre-rendered frames at 1 with Threaded optimization off (I usually kept it on); I can confirm that they don't give the same results, no where close actually; there is definitely some input lag with the latter, no doubts what so ever - at least on my PC, different set ups will likely give different results.

    I play CS:GO a lot, getting close to 7k hours :cool:; and having a more responsive aim is more favourable over anything else. I will give this one a go; I am happy with the input latency now so as long as it isn't worse, I'm fine with it.

    lowest setting are like a old prerender frames 0 and without threaded optimization?

    Well I know its definitely not pre-render frames 1 with threaded optimization. There were some theories that it may be pre-render frames 1 without threaded optimization, but that is wrong as well. I don't recall if pre-render frames 0 was a thing, but 'Lowest latency' for sure has lower latency that the other two I mentioned.

    Agree, just tested in AVP2010, and it felt like I would almost have to lower ingame sensitivity

    TJ, are you using that in conjunction with g-sync?

    With this driver my CPU gets reaal hot and the CPU fan go to 100%
    In Core temp i see 30w usage and normal that is 1.6
    The CPU temp is getting up to 70 degrees
    After reinstall 432.68 Every ting got normal again :)

    This is all ad idle usage !
