To high bumps on Sebring. Do you agree?

    Just up the filter to smooth out the bumps. I did this aswell with my G25 back in the days. Using the filter at 32 or whatever is the highest setting...

    Commercial sims dumb down laser scans. Otherwise there would be far too much data for consumer computers to handle. His concern is legitimate.

    Sebring is.....Sebring. Penske went there with the brand new Porsche Evo Spiders with very stiff setups and had all sorts of issues. You have to setup for the track as well as set your gear. FWIW, I got more shake from my Logitech on the 3rd party versions of the track than I do now with the TS-PC on the S397 version.

    We raced an Rx7 in GTU in the 80's. Sebring setup took softest springs of the season along with judicious damper and brake bias settings. The rotary has very little engine braking compared to piston engine. Sebring requires a low damping level on front compression and with low damper settings front tires are more prone break traction on brake application. Engine braking helps a little to transfer just a little more weight to the front. There were a handful of folks in GTU and GTO who had progressive rate springs only for Sebring. We never tried them.

    Year after year Sebring had not so subtle changes on the severity of some of the key bumps. Its a track of floating concete blocks.

    As comparison we ran the stiffest setup at Daytona with about 1/4" travel to bumpstop on the banking - we would hit the bumpstops 2-3 times on the banking.

    Road Atlanta was medium hardness in setup. In those days the chicane at 10 didn't exist and we would have gone stiffer for faster laps, but in that configuration exiting turn 12 under the bridge if you went a bit too wide on the downhill exit adjacent to pit exit you would get airborne and a bulleyes with your name on it was instantly erected just before the flag stand. And FWIW, Flagging at Road Atlanta took the James Hunt style of Big Balls.....

    The F1 2013 Mod actually gets air in Sunset it's that bumpy.

    Sebring is a track that test's both man and machine in multiple ways; the rugged surface character is one of them. Some drivers experience issues with their vision during and after races there due to the harsh bumps.

    Not exactly. What commerical sims do is reduce the poly count significantly from the original point cloud, as otherwise no consumer CPU would be able to run the sim in real time. However, the points that are left in the game are still from the real point cloud. It would be an insane idea to start manually changing the position of the points obtained from the laser scan, and besides, it would take forever to accomplish. So we can with high degree of certainty trust that the points that are left are from the real point cloud.

    Right, and that much detail (original scan) is likely far too much for even DD-wheels to convey effectively anyway, so a reduction in points makes sense in other ways too.
