    For games in general you can get a pretty close estimate for what 5760x1080 performance you'll get, by using a dynamic super resolution that's close to the resolution you're "simulating". I assume it's the same in ACC. Activate DSR in the Nvidia control panel (if you haven't already) and test for example 3325x2078. That equals 6 909 350 pixels. 5760x1080 is 6 220 800. So they should be pretty close in the amount of pixels that need to be rendered.

    I found I could run 4k single easier than I can run 5760x1080 triples!

    I did the math and lowered res scale down from 4k to approximately the same pixels before getting triples and was getting better fps on the single with same pixels than I get now with actual triples.

    In other words, it's hard to simulate the load 3 screens makes on a single setup.

    I hope that makes sense.

    I just got second monitor and i would like to test dual monitors in ACC, on Iracing and AC everything works fine. Is there any guide on how to make two monitors work in ACC?

    Just make an Nvidia Surround monitor and use that custom resolution in ACC.

    The new res you created in Nvidia Surround should appear in ACC menu.

    I recently setup tripple monitors with my setup of

    Monitors - 1080p x 1140p x 1080p

    I set a custom resolution of 6400x1440p

    which is (1920+2560+1920)x(1140) Width of all 3 monitorx x height o my biggest monitor.

    It seems to work apart form the bezel lines are about 2 inches in from the edge of my center monitor. It doesn't matter what tripple screen settings I adjust these lines do not move.


    Is this because ACC assumes all monitors are the same width so just dividess the screen into 3 equal pieces? Do you think ACC will allow us to customize the width of individual displays?

    This is something you can try (it may or may not solve your problem but I tend towards the first):
    -remove the bezel correction in ACC view settings
    - create a new NVIDIA surround resolution with bezel correction
    - start ACC and select new NVIDIA bezel corrected custom resolution

    I can't use Surround as it has issues with monitors with multiple resolutions, I got around the issue by using SRWE and setting a custom resolution that was the width of my center screen multiplied by 3.
    However I still have a problem with scaling on the side monitors, as they are different DPI the image gets offset has you move down the screen, I've been attempting to rectify this with customer resolutions on my side screens but currently haven't found a workable solution.

    There may be another workaround that may lead you to the finish (experimental) - if (and only if) all three screens have the same aspect ratio you could try to:

    - determine the scaling factor from side screen to center screen resolution
    - use this scaling factor to create a custom single screen resolution for the side screens = you should end up with all three screens using the SAME resolution
    - now either use these three screens (the side screens "pretending" to be the same as the center screen) either directly in ACC (now with the bezel moved to the correct place) or create a NVIDIA Surround custom resolution

    I doubt this works but it just may ;-)

    You are correct, to get it to really work you have to make a custom resolution for the side monitors so that all 3 monitors have essentially the same DPI. For my side monitors had had to increase the horizontal resolution to 1250 (From 1080 native) and this looked about right, i did this via trail and error so could probably be more precise.
    The downside is the monitor can't really handle the odd aspect ratio so text and other things looks stretched and blurry. Oh one thing, you have to turn off resolution scaling in the nvida control panel otherwise it does not work. I wonder if anyone has come up with some sort of calculator that can take your existing resolutions and come up with the correct mathematical answer, so far I've been unable to find it.

    Did you ever get this to work completely?
    I ask because i have the exact same issue with triple monitors using SRWE.
    And also one more question: Additionally for me when using SRWE the taskbar stays visible in ACC. In AC this does not happen with SRWE. Did you have this issue also?
