Performance was possibly the only reason for removing and replacing the beta forest with a more “console game” looking forest. But today we have 8 or 12 core CPUs with 16 or 24 threads and 4,5 GHz on all cores. We have 16 GB DDR4 RAM, a 64-bit OS and modern Turing/Navi graphic cards. So let the console version have the current forest, but make the PC version looking better please. Don’t understand me wrong. The game looks very good on PC, but when I see the beta forest, I feel even more immersed.
You could even experiment a bit and maybe add and polish it for a patch 2.0.
