I edit the .~/local/share/ov/pkg/isaac_sim-2022.1.0/apps/omni.isaac.sim.base.kit file and modify as below:
[settings.app.renderer]
skipWhileMinimized = false
sleepMsOnFocus = 0
sleepMsOutOfFocus = 0
resolution.width=1920
resolution.height=1080
# [setting.app.runLoops]
main.rateLimitEnabled = true
main.rateLimitFrequency = 30
# main.rateLimitUseBusyLoop = false
rendering_0.rateLimitEnabled = true
but i not work, the viewport resolution continue to be 720x1280 and the edit->preference->render->FPS limit continue to be 120.
I am really confused . Thanks very much if you can help me.
