    Start MSI ab and have it running in the background, now enable OSD monitoring so RTSS appears, now open RTSS and add a game to the list, config it there.. Or just set it in global profile.
    Also enable 64bit encoder if you're planing to record with it...

    thanks -Tj- but do i really MSI:AB? i always uninstall MSI:AB & i just using RTSS running behind the background so that's the reason behind y i can't limit the frames?

    i tried running MSI:AB & RTSS in the background, set 60 fps on RTSS but yet my dota 2 & FIFA 15 still gave me screen tearing especially the worst in FIFA 15.

    FYI, i removed the frame limiter on NVIDIA Profile Inspector. don't have luck with RTSS at all.

    I have a 60Hz GSYNC UHD Monitor, tested 30,40,45,50,55 FPS in DX9/DX11, with GSYNC on/off, VSYNC on/off, fullscreen and windowed. It starts limiting only above the refreshrate 80, 90 etc...


    I checked the export and it seems to be just fine here, can you give more detail which settings you changed on which profile, and what application you assigned on a custom profile?

    hah well no wonder it doesn't work then. RTSS needs msi ab to work properly.

    And force vsync on top to remove screen tearing.

    Hm, weird. When I had a 144Hz Gsync display, there were no problems with fps-locks below that refreshrate, e.g. 120fps with limiter v2.

    It also works well with my current display that doesn't have Gsync:
    [​IMG]

    But I noticed that the actual value is not always accurate, e.g. it was suddenly different when using 1080p upscaling instead of my native WQHD resolution.
    Maybe it is related to your 4k resolution?


    It seems to affect only profiles that have been created by user.
    Example: I create a profile for testexe.exe. When I export this profile, there is no exe-name linked in it, the profile name isn't saved either:
    Code:
    <?xml version="1.0" encoding="utf-16"?>
    <ArrayOfProfile>
      <Profile>
        <ProfileName />
        <Executeables />
        <Settings />
      </Profile>
    </ArrayOfProfile>
    Another issue would be that Nvidia is setting up a lot of flags for most profiles that come with the driver. Is it not possible to save them when exporting the profile? It seems only settings are saved that are changed by user.
    So e.g. you can't make a backup of the profile if you want to try out what happens when you delete it.

    Btw: I just noticed that it's not possible to link ModernUI Apps (Metro) with their exe-name. Instead, we need to link a folder-name (of course not Inspector's fault).
    This can be done by modifying an exported profile with an editor.
    For example, it could look the following for the game Minion Rush:
    Code:
    <?xml version="1.0" encoding="utf-16"?>
    <ArrayOfProfile>
      <Profile>
        <ProfileName>Minion Rush</ProfileName>
        <Executeables>
          <string>GAMELOFTSA.DespicableMeMinionRush*</string>
        </Executeables>
        <Settings />
      </Profile>
    </ArrayOfProfile>
    (wildcards work and make sense because the folder name can change with game's version number)
    Maybe it would make sense to offer an option in the Profile Inspector to link folder names instead of exe name or exe absolute path?
    But probably not very important, since important ModernUI games like Gears of Wars should always have a working profile by default from Nvidia.

    Btw: Thanks for the improvements with the Profile Inspector, its speed and responsiveness compared to old Inspector versions are really nice!

    Quick question:

    If limit@59fps + TripBuf VSync@60hz reduces input lag but causes each 1/60 frame to "stutter", why even use limiter@60fps with VSync, doesn't Vsync automatically limit framerate to 60 by itself?

    my DVBViewer profile is also custom created, it seems this only happens if you have not changed a single setting, thanks for the hint i will take a look into it.


    if you choose "export all customized profiles" you can also only select the single profile, and theres a checkbox "include predefined settings". ;-)


    i dont have win10 but i think i can make free input to get working as well

    Ah, that's why. :)


    Didn't know that, thanks!

    :)

    I checked 4k with DSR, still fps-limit works without problems below refreshrate (if the difference to refreshrate is at least three frames).

    Self-bump for clarification?

    No. Vsync synchronizes the timing of frames and monitor refresh, so that each frame being sent to the monitor is complete (instead of sending half a frame and causing tearing). Vsync = Video Sync

    At 70 fps on a 60hz monitor, it will appear to be limiting the framerate (depending on the vsync mode, it probably IS limiting the framerate).

    At 59 fps on a 60hz monitor, it is showing 1 less frame than the monitor can display. So 1 out of the 60hz can end up showing the same frame, because the gpu is not sending anything new.

    Anyone who knows more, feel free to correct me :)

    V-Sync = vertical synchronization

    But does Vsync limit game engine's framerate to 60, or does it simply pick every 60 frames out of your XYZ prepared/buffered frames? Simply put, does vsync also work as frame limiter per se?

    So how to enable Frame Rate Limiter v2 Control on Other in Nvidia Inspector Profiler.

    The default is 0x00000008 , if I have Pascal do I need to change anything ?

    Do I need to enable Vertical Sync Smooth AFR Behavior ?

    And Frame Rate Limiter Limit to 60 fps ( Frame Rate Limiter v2 ) or such, I'm using 59 Hz in some games.

    Is Frame Rate Limiter v2 is better to use than RTSS ? When I use Rate Limiter v2 or the ones on RTSS I need to enable normal Vsync in game or in NVCP ?

    Personally best setting for me it's: Fps lock to 60 and Adaptive sync enabled. ( 59 causes rare hitches for me)

    To lock fps best options are:
    Frame limiter V2 or RSTT... The latter reduce a bit performance but it seems more stable, I'm still experimenting on this...
    Would be great someone to test with FCAT to have objective results.

    I just wanted to say , thank you for the knowledge this forum brings .
    I have now found the perfect fps limiter to limit games to 30fps without any stutter or any other third party programs , and no input lag.

    If you own a kepler 600 series or 700 series this is the right settings for you:
    1. uninstall RTSS or any other third party fps limiter
    2. download nvidia inspector 2.1.2.15
    nvidia inspector settings:

    frame rate limiter : 30 fps (frame rate limiter v2)
    maximum pre-rendered frames : 1
    vertical sync : use the 3d application setting (or force on)
    vertical sync tear : standard
    frame rate limiter 2 control : 0x00000020 PS_FRAMERATE_LIMITER_2_CONTROL_ALLOW_ALL

    Finally after years and years of stuttering mess, now its perfect 30 fps console like smooth with no lag and no RTSS.

    All good but it's 30 Fps :\ compare to 60 Fps it's day and night

    Uh you're doing nothing to remove tearing though. Consoles use adaptive v-sync or adaptive v-sync (half refresh).

    No screen tearing because you use vsync ingame or force on.
    vertical sync : use the 3d application setting (or force on)
    vertical sync tear : standard

    Seems like an overcomplicated way to achieve half refresh V-Sync. And I'd imagine the input lag is quite heavy, though probably less noticeable with a controller.
