Tried this on my PC and it is silky smooth. Exceptional work! :)
My specs for anyone thats interested:
OS: Windows 11
CPU: Intel Core i3-10100 (4 cores, 8 threads)
GPU: NVIDIA GeForce GTX 1060 6GB
RAM: 16GB DDR4-3200MHz (2 x 8GB)
EDIT: Okay, it isnt as smooth in city areas with some 1% frame drops and stutters (Nice for example) but its still playable and is significantly better than the Xbox 360 version. Amazing that this was done in the first place.
