    Just try yourself and you will understand.

    If you want to play that resolution you' ll have to run everything on low/medium graphics (no high, no ultra, no epic) or else you 'll play at 20/25 fps.
    It's up to you to choose what you like but please don't come back here asking why your FPS are so slow, and you want to run ACC at High settings because you have a super top notch PC from outter space :D

    A 1080TI will never drive a 7680x1440 with high/epic graphics and high FPS !
  2. is it possible to know of to do that change? ( sorry if I don't know how to change in the menuSetting.jons file):confused::)

    Thank you

    this problem is only in ACC ..

    in AC online game with full room at 100 fps ..

    before touching anything, if I set the three screens without bezels in Nvidia surround ..

    When I change the game do I have to reconfigure the screens in Nvidia surround with bezels?

    I am happy with the triple screen support. Improvement would be if it would work without Nvidia surround like PCars2. Activating surround with key combination does not work. Deactivation does work though. It is the same key combination since.

    The shortest instruction to enable triple screens in ACC in nine easy steps:

    Only follow steps 1-9 and you will be sorted - you may skip the rest of the text ;-)

    1) Set up NVIDIA Surround in your GPU driver panel (BOTH native 1:1 resolution AND bezel corrected resolution will work)
    2) start ACC
    3) open VIDEO options
    4) choose correct NVIDIA surround resolution
    (either native or bezel corrected to your taste) 4
    5) ENABLE triple screen rendering
    6) start a session and go to the track
    7) hit ESC and enter the VIEW SETTINGS
    8) adjust all triple screen relevant settings here to neutralize any perspective distortion and adjust bezel correction (ONLY IF YOU USE NATIVE RESOLUTION)
    9) enjoy

    What is the difference between choosing to run native resolution NVIDIA surround (without bezel correction) and bezel corrected resolution you ask?
    native resolution:
    - you have to use bezel correction settings in VIEW SETTINGS in session to correctly dial out any bezels
    - some in game elements will not be bezel corrected currently (for example the showroom, UI backgrounds, etc), as VIEW SETTINGS bezel correction only influences in game session, not the UI
    - depending on your system setup you may or may not be able to run ACC this way in borderless mode and be able to more quickly ALT-TAB to other applications
    - all in session cameras work properly bezel corrected

    bezel corrected resolution:
    - all in game elements will be properly bezel corrected (including full UI and showroom)
    - some rare cameras like free camera (F7) may not be bezel corrected this way - but all relevant cameras such as all driving views work PERFECTLY corrected ;-)

    Personally I prefer to run ACC currently with a NVIDIA driver panel bezel corrected resolution as it provides proper bezel correction in all game modes and interfaces (only exception so far is the free camera (F7) which I rarely ever use when actually running ACC outside of fiddling around ;-)

    many thanks !!!!

    perfectly explained.

    it's like I have it, with the bezel corrected from Nvidia, and it's going perfect for me.
    what I have always referred to is that it is going to pull me in some moments
    It will be a matter of performance or touching parameters.

    but I am surprised that I see AC better than ACC, and that it goes infinitely more fluid AC.

    Has anybody else noticed some white lines on the border between the screens when in triple screen rendering using the built-in bezel correction? I will try and post screenshots later if I can.

    Maybe you're in windowed mode instead of fullscreen...

    I'm using windowed mode and I'm not seeing those white lines either.

    I found the issue: I had render resolution set to 83% instead of 85%. With 83%, I get these horrible white lines.

    I guess it's a side effect to underscaling the resolution.... but i would advice to never go under 100% and lower some render settings instead if you need to gain some FPS ;)
  15. fnegroni

    fnegroni Racer

    I actually prefer 85% scale with temporal upscaling. Some of the debris for example looks more realistic than lowering the quality of materials or effects. Especially since my 1080p centre screen is only 60cm from my eyes so a sharper image makes the pixelation distracting. It’s down to personal preference I suppose.

    Yeah I also prefer a slight downscaling. Easy fps gain without much loss in quality.

    Lets say I want to buy 3 monitors with freesync. Although there are only 12 freesync monitors nvidia recognize to pass their g-sync standards I have read that a nvidia 10/20 series GPU can somewhat utilize this technology for monitors not within that 12 monitor list however one of the requirements is that a display port must be used rather than hdmi. The issue i have is my gpu only has 2 x dp and 2 x hdmi. Am I screwed for this scenario? If I have understood this correctly I must upgrade my nvidia GPU to one with 3 display ports.

    I have four monitors. Two on hdmi two on DP. If I use my gsync monitor on DP in the middle and the hdmi monitors on the side, and enable nvidia surround, I can still have the centre monitor in gsync mode. But if I connect my non gsync monitor to DP and try and use the free sync support, it doesn’t work.

    Thank you for the confirmation. Curious, what are your thoughts on adaptive sync? I have neaver had any tearing issues on my 120 hz monitor. I do however get a little once in a while on my 60 hz hdtv. My concern is I can tell when my 120 hz monitor is accidentally running in 60 hz mode therefore if I have triple 144hz monitors there is no way I can run 144 FPS therefore the refresh rate may drop to 80 or 90 etc.. If the monitors don't tear wouldn't it be better to leave them on 144 hz and leave adaptive sync off?

    If you can get a gsync centre monitor, two 144hz side monitors, same make and tech (TN orIPS) and colour calibrate the triplet to match somewhat, you would enjoy gsync and wouldn’t notice tearing on side monitors.

    I have triple 144hz. I can’t see tearing and I average 90fps (peak 120) in ACC. Can easily go past on AC1 and iRacing for obvious reasons.
    When I tried my gsync monitor (144hz), which is used for FPS games these days, as a middle monitor in a triple setup, I could tell gsync was working well and making the image much smoother. It was definitely noticeable in the middle screen. It wasn’t so noticeable on the side monitors, but could be noticed on 60hz, but I’ve not had tearing issues since going for a triple 144hz and no free or gsync.
