I don't use GTR2 for any racing types other than GT style racing, which is my personal favorite anyways. Haven't had a good straighting for a while If someone can point out my being wrong please chime in and straighten me out. Why can it be done in rfactor and not GTR2 ? Because rfactors physics are more versatile and not locked to a specific style of racing. In rfactor it's not a problem to get a little air. Try getting a GTR2 Off Road mod airborn on the track, and I don't mean flying though the air after a crash, LOL. Why ? Easy, the core physics of GTR2 have been tuned for GT style racing. rfactor seems to do the various racing types well (minus the AI needing work), where as GTR2 does GT type racing great, yet off road and even oval racing on GTR2 fall behind. How much so on the core level is above my pay grade.Īs for rfactor being more versatile all you have to do is compare various mods on both sims. I can only go by what I've personally tried and have driven over the years on those two sims and there is a difference in the physics engines. I believe he knew/knows some of the SimBin fellas and could easily debunk or confirm what I have mentioned. I haven't done any rfactor to GTR2 conversions for years so I can't even suggest what mods to play around with so that you can see and feel the differences by doing the physics package swap.ĭavid Wright would be the fella to try and get more in depth info from regarding GTR2 physics. You may have to edit/tweak a few things so as not to get a CTD or have the wheels looking like the car is a monster truck, but it should run and then you can compare the two sets of physics files and see the differences in game and line by line. Then swap out the original GTR2 physics files for the rfactor versions and see how the car runs for 20 or so laps. ![]() I remember heat buildup and cooling of the engine and brakes being of different values between the 2 sims.įor a fun test, find an rfactor mod that has a similar car to one of the stock GTR2 cars, say an NGT Porsche or Ferrari. I do take some of the entries from the rfactor versions to get it close in performance but the heart of the physics files are good ol GTR2. When ever I've converted a car from rfactor to GTR2 I just use a physics package from one of the stock GTR2 vehicles (or a mod with permission) and then tweak it to suit the car I'm converting. Regardless, both ways need 3DSimEd to do it.Įngine curve data is ok, just like gear ratios, it's some of the other engine values that GTR2 looks at differently. Then there are those who basically rebuilt the rfactor car/mod/track from the ground up to work flawless in GTR2. There are a lot of piss poor rfactor to GTR2 conversions where the individual just did what they had to so the rfactor mod would load in GTR2 without a CTD. The nice thing with Race07 is that the physics files are pretty much drop and drive so other than a few optional edit tweaks they work without issues with Race07 to GTR2 conversions. ![]() GTR2 may use the same gMotor2 game engine but it was rewritten for the type of game that GTR2 simulates.Įven the Race07 cars/tracks need to be opened, edited and saved in the GTR2 format and that's a SimBin product. Even some of the physics files need redoing when converting the rfactor cars. Not to mention that some material names need to be edited to match those of what GTR2 uses or results in a CTD.Ĭonverting rfactor cars to GTR2 is not like converting GTL cars where you can do it the poormans way and just rename a few files in Windows Explorer. The rfactor mesh file (xxxxxxx.gmt) is not compatible with GTR2 and needs to be opened and then saved in the GTR2 gmt format with 3DSimEd.
