Game launcher won't work for me, so I had to tinker with the config.json myself to create a borderless 1080p game window with a 144fps cap. Changes i made:

    "core-dump": false,
    "vsync" : false,
    "window-mode" : "Borderless",
    "fullscreen" : {
        "resolution": {
        "height": 1080
        "width": 1920,
    }
        "vsync": true
    },
    "msaa" : {
        "enable": true,
        "samples-count": 8
    },
    "temporalAA" : true,
    "motion-blur" : true,
    "fps-limit" : 144,
