tl;dr: because it’s a weak(er) GPU?
I’d expect the Quadro RTX 4000 to be slower than a 3060. Double check whether the card is sitting and working in PCIx16 slot first, though.
All versions of 5 have this problem
It’s probably directly related to Lumen and Virtual Shadow Maps (switch them off to get most of the UE4 v4.27 perf). And to clarify, hope we’re not confusing RTX Quadro 4000 8GB Turing from 2018 with a much more powerful A4000 from 2021.
Even though the card can RTX, I would not expect much from the 36 RT cores from 2018 when what we consider modern ray tracing was in its infancy.
On a side note:
i9-13900k, 128GB ram, SSDs + Quadro RTX 4000
Why?
