    What do you mean?
    I posted the bench screenshot.
    It doesn't show?

    Here is a direct link.

    oh I see now. thanks

    ---------------
    Just an update now that I have proper voltage on ram.

    Hey, hows it going?
    If I were to enable HPET in win10 would it have any kind of effect on RAL?

    No - I use QueryPerformanceCounter and it is not dependent on HPET AFAIK...

    Good to know thanks. I understand that if you don't enable or disable it in win10 it's default is more like a default "standby mode". It won't turn on until an app, driver, etc request it's use. I was just wondering if RAL actually did.

    I also noticed that Nvidia got on board with it as well. Congrads, you made them angry, LOL.
    I can tell to because even though they offer it they down play it as just a "reduction pre-rendered frames".

    Yup - NV implementing it is a personal win for me :) Of course their implementation is lacking at the moment - they need to go through the same iterations I did to make it better...

    About prerendered frames - this is a self-sustaining urban legend, which refuses to die. NV are not saying that ullm is that - it’s all some stubborn users... :)

    Sigh, one day they will get it. One day...

    I'm a bit confused to the "different options" that Nv offers though. From my understanding either you want it on or off. IE: latency reduced to the best it can work. Or, disable it.

    It’s not that simple. The regular NV low latency mode is indeed “force 1 prerendered frame”. On AMD this is the default mode, but on NV having more prerendered frames might improve FPS in some cases. As for ULLM (or RAL) - this incurs extra CPU power consumption, as well as sometimes reduced FPS (although still improved latency). For RAL I believe we mostly fixed the FPS reduction issues (at least on DX11) - but NV still has that road ahead of them...

    Ah, I see. Thanks for the clarification.
    BTW, I left a message for you under "conversations" not sure if you can see it on your end.
    Click/look at your user name in the top right corner of the website. You should see a red icon indicating a message.
    I'm note sure how it looks if you aren't using "desktop view".

    who knows how to switch off anti-lag mode via registry? it seems by default anti-lag mode is ON at boot. I have A4Tech mouse with Bloody software and i can see weird behavior of my mouse. I think Adrenalin software overrides Bloody software settings and it looks like it changes mouse CPI rate. If i press Alt+L either close Bloody software and then re-start it is fine. Sometimes it happend in games(espacially Far Cry Dawn). So i would prefer to switch off this function for beginning. is it possible?

    Question:
    Are you using MarkC or other registry tweak to remove acceleration?

    Nope, but i think i should play with that later. Thanks.

    @HiAlgoBoost Does "Anti-Lag" use some sort of "Dynamically" sized flip queue? I'm wondering why it's not enabled by default and how it's different from the old options of simply changing the flip queue size.

    We know it reduces input lag over default, but historically reducing the flip queue size could either reduce overall fps (slight to meaningful depending on game) and/or cause more discernible hitching/stutter so it's important to know if the new Anti-Lag setting retains these historical drawbacks.

    Generally speaking there's a reason why the default is what it is for this sorta thing was my understanding. I did see on hardware unboxed that antilag does reduce overall fps in the same way more or less that reducing the flip queue size does, but they didn't mention or really even seem to take a look at hitching/stutter/smoothness with antilag on vs off.

    I currently have an nvidia card myself and their own Ultra low lag mode causes hitching/stutter out the whazzoo in many games I test (with uncapped fps at least).

    Limiting flip queue size to 1 hardly ever reduces performance, you can test this also on AMD e.g. with DXVK API wrapper. It also reduces stutter instead of increasing it, this is very noticeable e.g. in Crysis 3 in GPU limit.

    I haven't experienced any hitching or stutter when using anti-lag. I believe it works by matching CPU to the GPU to make sure the GPU isn't being fed too many frames at once, therefore reducing the GPU bottleneck and making them work more closely to each other.

    @HiAlgoBoost Stuff like this is a massive UX problem that stops you from getting the important message across. It creates confusion instead of impressing people. I'm falling in love with Unicode misc characters (not emojis ;) ), why not make a really clear indicator of whats going on?
    Like this: "FPS→AL-FPS" which will look like: "42→47"
    Now the reliability of the reading is on you, but I feel it's the polish that gets nVidia so much further than AMD/RTG.

    On-topic: I will update the drivers and post my findings tomorrow (mainly CSGO and couple others)
