    You need to provide more info so the community can help you.

    • Specs on your computer, CPU, RAM, GPU…
    • utility being used to capture game footage, and format you are capturing to.
    • “media info” on the captured media.
    • Project settings in Vegas.
    • Desired rendered output / Vegas Render As template
    • Preferences settings in Vegas.

    Seriously this request should be a sticky on the forum to guide people on how to post for help.

    Under OBS -> Settings -> Advanced – is the CFR (constant frame rate) checked?

    Download a copy of “Media Info” and verify the OBS encoded media is being encoded to a constant frame rate of 60 or 59.94 FPS.

    Try the results of using the x264 encoder vs using quicksync or NVENC.

    Try disabling smart resampling for media clips on the timeline.

    Try Xsplit Broadcaster, as OBS fails to encode to a “video standard” Below is a media info output on an xsplit file:

    Video
    ID : 2
    Format : AVC
    Format/Info : Advanced Video Codec
    Format profile : Baseline@L3.1
    Format settings, CABAC : No
    Format settings, ReFrames : 1 frame
    Codec ID : avc1
    Codec ID/Info : Advanced Video Coding
    Duration : 23s 12ms
    Duration_FirstFrame : -21ms
    Bit rate : 113 Kbps
    Width : 1 280 pixels
    Height : 720 pixels
    Display aspect ratio : 16:9
    Frame rate mode : Constant
    Frame rate : 30.000 fps

    Vegas is a Video editor that likes encoded source material that conforms to video standards in the TV and Film industries. The video standard in your use case would be 1920x1080x59.94P FPS, or 3840x2160x59.94P FPS. A straight 60FPS should work too, but Media Info results similar to 58.465 to 60.366 will cause playback issues in Vegas.
