They claimed that it was expensive and was part of the reason for cyberpunk’s turbulent launch.
It’s a real shame though, most UE5 runs awful it seems, and are still limited by single thread performance, unlike RED Engine which scales far better with more CPU cores.
Tbh RED engine also has its plethora of problems, missing features, and makes it harder to onboard new team members (need to train on new engine instead of basically every single dev having experience with unity or unreal).
Not that unreal is perfect by any shots.
