Resolution missing - 1920x1080 @ 60 Hz

[Mito125]

I'd like to set resolution to 1920*1080 @ 60 Hz like my monitor but I can't find in option... This is my screenshot http://steamcommunity.com/sharedfiles/filedetails/?id=452716917

Where can I find @60Hz??? Why I have too options with same frequency and same resolution???

Thanks.

lil odd i have the option but .06Hz will not matter nor could you see with your human eye ballz

The highest setting for 1920x1080 is 59.94hz. I also have a 60hz monitor and that setting works fine.

For me this is a problem because I need to record video... It's a problem for me... And why I have multiple same options???

I believe that 59.94hz is the actual rate. If you look at your video card settings you should see the same thing. Why should that be a problem for recording a video?

[Mito125]

My monitor is set a 60Hz... It's a problem because when I recorded the video with microphone for my youtube channel, they are completely out of sync... Only with this game I have the problem...

Are you *absolutely* sure you scrolled the list all the way down? In the screenshot, it does look like there might be a tiny sliver left there. Which would be the resolution you're looking for.

But why some option appears two/three times???

Hmm, I looked at my options menu and I have 60hz as well, not 59.94. Maybe something is wrong with your monitor? Are your drivers misconfigured? Unfortunately I can't really help.

lol its at the bottom 1920x1080p 59.9 hz

Just took a better look at your screenshot and noticed you don't have 60Hz listed on ANY resolution, only 50 and 59,94Hz. That tells me that your screen might actually not support the 'full 60' refresh rate. (my AC does list 50, 59,94 and 60 Hz) But can't you adjust your recording software to that?

Because they are modes with different attributes on them (attributes which that list doesn't show)

If you look in your documents folder for assetto corsa and in there there's a logs folder. The top of log.txt you'll see the list of modes it gets, like this :-

mode 119 1920 1080 24[24/1] UNSPECIFIED PROGRESSIVE
mode 120 1920 1080 50[50/1] UNSPECIFIED PROGRESSIVE
mode 121 1920 1080 60[60/1] UNSPECIFIED PROGRESSIVE
DISPLAY MODE FOUND <--- this is the one I'm using
mode 122 1920 1080 23[24000/1001] UNSPECIFIED PROGRESSIVE
mode 123 1920 1080 59[60000/1001] UNSPECIFIED PROGRESSIVE

You can see some of the entries that have more than one might say "CENTERED PROGRESSIVE" - presumably if you delve into the directx api you'll see the calls kunos are using to get this list of modes.

Basically the game is using dxgi to get a list of modes - and these modes are combination of what your GPU and monitor support. These days the monitor reports what modes it supports, years ago you used to have to give it modelines in linux with all the timing information on. Presumably this stuff was in inf files for windows. And there were common standardised vesa modes - which is why if you remove your graphics drivers you end up with windows booting at 800 x 600 or something like that.

Thing is, as you can see above for timing, some modes are 60/1 24/1 and some are 60000/1001 and 24000/1001 which is where the 59.94 decimal comes from.

59.94 is 60hz. It's whatever is supported by your monitor and it's your monitor / GPU reporting these timings to the OS.

Note, when you choose a mode the game (via directx) sets the gpu and monitor to this mode - so if your monitor says "60hz" for these modes, that's immaterial. You're not setting the game to 59.94 and the monitor to 60hz or anything like that.

This is not what is causing your audio sync problems. More likely issues with whatever you are using to capture or edit the video is. Noting that most of the FPS values you see in videos are fractional too - i.e "30fps" is usually 29.97 for the same reasons - the timing of the device is usually 30000/1001.

Here's a couple of links to an explanation of the 59.94hz issue https://forums.frontier.co.uk/showthread.php?t=110574 and https://support.microsoft.com/en-ca/kb/2006076

It is driver related. With an AMD card and a Samsung 46C6000 TV, I'll have 1080P@59.94hz but 60hz will be available with VSR resolutions like 2560x1440 or 3200x1800. If I type alt+enter during the game, it will go borderless fullscreen @60hz instead of 59.94hz.
Editing the registry or Custom Resolution Utility could help with the refresh rates but I don't know what values to modify on Windows 10.
