In the video above, Brandon carefully goes through each step in the installation of the R.E.A.L. VR mod for Indiana Jones and the Great Circle. Remember that RealConfig cannot automatically set the graphics options for you in this title, since the game encrypts its user options files, so you might find the section from 1:00 to 5:00 particularly helpful to double check that you have set all the required options correctly.
From 5:00 to the end of the video there's an advanced deep dive for tinkerers, where Brandon talks about configuration files and presets and suggests ways to customize the engine's cvars so that you can achieve the best possible compromise between image quality and performance. This final section is not for the faint of heart!
