    Anybody else missing the 60Hz option in video resolution setup?
    I have 1920 x 1080...but only at 59Hz (twice)...no 60Hz.
    I've searched but couldn't find anything.

    Yeah, happens to me when using HDMI. 60 Hz becomes available using DVI.

    Hey!

    I got a solution for you. Since you both have a Nvidia GPU do this. Go to Nvidia control panel. There you select Change Resolution. On the bottom you will see a button Customize. Click on it. Than Click on the create custom resolution. There you can setup which resolution you want to create. under that you can set refresh rate. Set it to 60 and apply. You can select 1980x1080 with 60hz in the game ;)

    Cheers!

    Edit: If that doesn't work I have another solution which will work for sure. Let me know if it helped you ;)

    Some monitors run slightly under 60Hz (like, 59.90) and it just rounds those down on the display.

    Nope :-(
    That doesn't work. NV cpl is set to 1080p / 60Hz (Native resolution) and I can swich between 23,29,50,59 or 60 Hz, but in assetto only 23,29,50 and TWICE 59 Hz can be selected. Happens in all resolutions higher than 1600x900.

    Ok :)

    Repeat everything as I wrote but with only difference in the last step. Do you see in the same tab where it says Timing? It is set to automatic. Set it to manual and set refresh rate manually to 60.01. Accept it and accept later that resolution in the Nvidia control panel.

    it's not related to AC ... usually the monitor runs on 59.9xx hz. Some applications will show it as 60hz, 59hz, and some will show the exact number .

    Yes :) But you can always force monitor to show 60hz by the options I have described :D It should work :)

    I don't run V-sync but I do have AC framerate capped at monitor refresh rate.
    While my framerate is extremely smooth, I do notice a very, very slight shimmering.
    I was wondering if the 60 fps cap vs the 59Hz default setting could have been causing it.
    I'll now drop the fps cap down to 59 from 60 and see if it goes away and report back.

    So what's the reason for not using it ? You're already limited to your Hz so why not get rid of tearing as well ?

    How ? Vsync will only prevent frame tearing as he already caped the rate.

    vsync adds delay to the frame being drawn so it is not drawn too early.

    Actually it forces the GFX to wait with the next frame until the display sends info that it's done displaying the current one, preventing frame tearing.

    This obviously introduces a minimum output lag vs a not synced capped rate but the pros of using Vsync are much bigger then the cons of tearing at capped rate.

    Much theory here so just try it, if you're capped at your refresh rate then enable Vsync and see for yourself - it's a different story if you're getting 150 FPS on an 60Hz display - Vsync will then seem laggy but when capped then the difference is not worth not using Vsync.

    It adds lag because the frame is being drawn on your screen later. Later=delayed=lag. My advice is and always has been do not use vsync. It adds lag which will make driving and controlling the cars a lot harder. Ac may be a special case but the best to deal with tearing without adding lag in general is to use uneven fps limits. Say cap fps at 83. 83/60=1,3833.. so the tear become impossible to notice because in the each frame it is drawn in different place. Using the same fps as your monitor Hz is the best way to get tearing. Why would anyone do that?

    Maybe it is a personal preference. I run about 120fps (more like 60-130) uncapped. I don't see tearing. Maybe I'm just not specially sensitive to it. But I hate input lag and I'm more sensitive to that. So obviously my preference is high fps which means low input lag and definitely not vsync on.

    exactly!

    i was playing a long long time with settings and my preferred option in other sims is 120Hz vsync. in AC this doesnt work right.
    my final setting is: 60Hz frame cap AND vsync. Dont know why this works in AC, but the result is a very very smoothed frameflow with less lag like vsync only. i tried this with 120 hz, but its still stuttering.

    at the end i leave it to 60 Hz and now i can use all postproc and all options to high - but reflections to static. and with daubsters mod v4 (and higher brightness) this sim can make me think sitting in a real car....

    Did you try 5760*1080 @ 120 Hz and 83 fps framerate limit?
    It's a classic and it works fine.
