Math Question [FPS Prediction]

[TheNoobie]

I know how to do latency prediction and speed prediction (quite obvious.) I'm a little confused about frame rate prediction though. Obviously if a client has 30 FPS than his game will not update as quickly as someone with 300 FPS, even though the server (think online games) will be updated. How do I compensate for the FPS loss in a situation like this?

For speed it's something along the lines of...

ClientsRealPosition = ClientPosition + ( ClientSpeed - MySpeed )

For latency it's something along the lines of...

ClientsRealPosition += Vec( fLatency, fLatency, fLatency )

For FPS it's something along the lines of...

// No clue
