By default AI should be about 2% faster in quali; remains an issue with AI being too quick in practice sessions) Increased rearview mirror resolution for all cars Corrected FOV / POV + tv cameras to the same standards for all cars Updated rumble sounds to be more "bassy" on all cars (for Buttkicker and other similar systems) Adjusted trackside cameras in all tracks for more realistic framing / tracking Adjusted some inconsistent road & terrain properties, fixing some overdone high frequency bumps Various environmental / lightining enhancements (new skies / fog and other updated shaders); Introduced new Foliage shader which looks better & is more optimized to provide performance boost Added 3d tyre lods at Granja Viana to help ease performance issues Added 3d Armco at Interlagos Known issues: The F-Extreme ERS system has been simplified for this release - basically, the battery is fully charged all the time and the power blending still needs work, meaning the driveability under throttle is not quite what it should be yet; The AI for the F-Extreme does not use 8th gear or DRS; The hard compound for the F-Extreme & F-Reiza does ot have its proper orange Pirelli sidewall label. Championship races are being awarded double points. All these should be sorted out in time for the next update. Please direct your bug reports on v1.21 to this thread.
