As far as the BETA goes, it's definitely not up to Reiza standards.
This seems more like a generic rFactor mod, to be honest.
* Low quality sound transitions from engine revving (you can hear the transition from low to med to high RPM sound);
* Steering rotation locked to 180 degrees, wich is super weird;
* Physics feel wrong to drive in general, not to mention the left tire is heating up more on an anti-clockwise circuit (should be the opposite);
* 3D models and textures are not up to modern standards
