FSDreamTeam has posted a brand new preview video demonstrating the upcoming PBR update for GSX. According to the developer, the update will feature new vehicles and characters, a new camera system, a new rendering system for logos, and much more. No additional information was provided. Keep in mind, PBR is applicable to Prepar3D V4.4+ only.
You may recall, back in December, FSDreamTeam also previewed jetway PBR effects with respect to GSX Level 2.
