Absolutely not. Their latest version of the RED engine is far better at utilising the resources available than UE5. UE5 is still to some degree limited by its render thread and doesn’t scale as well with more CPU cores the same way CP2077 does.
Most UE5 also seems to launch with major performance issues, and many of the recently launched games will be borked for all eternity as shader compilation stutters aren’t something more powerful hardware will fix.
It’s a real shame that the executives at CDPR doesn’t want to continue investing in the RED engine.
