We don't know if TMC works for 64bit apps at all and correctly (and other online services in general), because we don't have the necessary licenses and the software is only partially cr*cked. We don't even have a decryptor for the new lua files

TTS is no problem
VR is more a matter of operating system release than iGO itself
