F1 2002: Physics rate and ride height??

After playing F1 2002 for a few months, I finally changed the physics rate to 0 (full) like many people suggested. Guess what, my times in Austria were consistently worse. When I digged in the telemetry tool some more I noticed that my ride height is exactly *half* of what it used to be! What is going on with that? Before I was bottoming out three times in the whole circuit. Now I'm hitting the road every time I get close to top speed and every time I hit a bump. Is that normal? Is that what I can expect by changing the physics update rate? Did you have to tweak all your setups? I never saw this mentioned anywhere, so I'm suspecting not everybody has this happen. Amdi

Well I can't say I had to change setups cuz I went to zero right from the get-go...but here 'might' be a logical reason. With half rate sampling, the physics have to skip to keep up. So if the car is beginning to drive over a bump, before the physics can measure, adjust, react and complete the process of moving over that bump, it has to skip ahead and get ready for the next imput comming in. At full rate, the sampling is not leaving, or quitting BEFORE completely driving over the highest point of the bump. So in the past, you could run artificially low ride heights because the physics engine at half rate just wasn't able to compute the full value. Now with the full rate sampling enabled, you are getting a more accurate picture of the track. You can use the tire temp lcd screen to view the plank dragging and guage with that if your ride heights are too low. Good luck. dave henrie
