Timesharing?

When my app is windowed I want it to politely 'timeshare' with other Windows' apps, possibly even other 3D programs.

I have a vague memory of someone saying that the Delay command releases time back to Windows for the duration that it's set.
Can someone confirm this.

Or is there a better way?
Possibly Blitz Support might best answer this?

Using Delay will free up CPU time. Try 5 or 10 for starters and use the Task Manager to see the effect.

If you're crazy, there's a dll somewhere that checks free system time, so your program can decide how long to delay for.

No, that's fine.
Thanks James, that's what I wanted to know.
