That's correct, there is no more option in the UI. You can use "safe mode":
Starting in Safe Mode
If X‑Plane detects that it crashed the last time it was run, then on the next start, you have an option to reset the rendering settings. If you reset the settings, you might avoid a crash on startup if the rendering settings were the cause of the initial crash. You may bring up the option to enter safe mode only if you start the sim with the shift key pressed down.
