To your question, the answer is yes. The modeling of the cars is incredible and they go to extremes to model everything from power delivery to suspension performance for every individual car. Their physics engines are on track with the
best flight simulators. Many games let you buy upgrades or mods for your cars and even those are accurately simulated (changing shocks, tires, etc).
For the tracks, they are 3D laser-scanned in real life and are pretty much exact matches to the real thing in every respect, including surroundings - tire walls, barriers, stands, pit in/out roads, flag stands, etc). I still find the simulation
a little “cold” because while I have a force-feedback steering wheel for my Xbox (which simulates road forces with motors that give you steering feel/feedback), there’s no accurate way for a low-cost sim like mine ($300 steering wheel/pedal set and a race
seat) to simulate dynamic forces for braking, acceleration or g-forces. But the overall answer is yes, if your controls are good, the games can be very accurate in predicting lap times and the “cheats” that they give you, like showing you the correct racing
line on a track, are dead-on. So here’s a funny story that addresses your point. My first track event at Daytona was in 2019. It was my 23rd track event overall, so I felt comfortable registering for the intermediate group. Instructors are typically not required
for intermediate (although usually available if you prefer). So I wanted some experience on the track before arriving. Forza 6 has a Corvette C7 Z06/Z07 in the game that’s identical to my real-life car. So I did several hours of training on the Daytona track
in “my car” to learn the curves and the recommended racing line. When I hit the track for real, I was very comfortable with the layout and the correct line. My times were slower than the game since I was working up to speed while primarily trying to keep the right line. This worked everywhere except
for Turn 3, known as the “Rodriguez International Horseshoe.” The feel of that line was off for me for the entire event and I never felt smooth through that corner exit and into the short straight before Turn 4 (“The Dogleg”). When I got home I was trying to figure out why. I reviewed my footage from the Corvette Performance Data Recorder (an onboard camera / telemetry recorder that C7s had as an option). Then I went and drove the track on the Xbox again and
couldn’t help but laugh. When learning the track on the Xbox, one of my visual markers for the correct line through Turn 3 was the big Ferris wheel in the infield. Comparing my camera footage to the Xbox, I saw that the Ferris wheel was about 100’ further
down the track in real life than in the game. After investigating, I found that the Daytona Ferris wheel can be moved, and it was in a different spot during my event than when the developers scanned the track for Forza 6. And that bit of difference was the
reason I kept blowing the exit of Turn 3. So the scans are that accurate/important. It’s a great tool for HPDE people like me. For true racers people seem to like iRacing way better, but they don’t have a decent practice mode in that software (for just learning a track line as opposed to racing) and I could never get my
wheel to work properly with the game. I generally totaled my car before even leaving the pits, so I gave up on iRacing. -- charles From: Matt Boyd <ferrari308driver [at] gmail.com> Out of all the report, what I'm curious about is this comment: "My times were about 15 seconds off what I was running on Forza 6 on the Xbox in the same car, but that’s to be expected when your own butt and fiberglass are on the line with no reset button." I haven't played a modern day console game in a long, long time (I loved Ferrari 355 Challenge on the DreamCast and that's probably the last game I've played in a similar medium). Are the games (like Forza 6 on the Xbox) so realistic now
that if you get a perfect lap on the game and then take the exact same car out and got a perfect lap, you'd expect the times to be identical (or close)? Just curious. Thanks for the report! -matt 85 euro 308 On Tue, Jan 31, 2023 at 6:31 PM Charles Perry <charles [at] carolinasound.com> wrote:
