Played this on my friends Epic account yesterday, Not impressed, I played Crysis 1 with Rygels texture pack and a few other little texture updates, Blackfire Mod etc... a few days ago, Minus the update to particle FX, Lighting update and RT on the water, They made very little effort with this game and in some instances the modded original can look better, That's not even taking into account the terrible CPU and GPU utilisation.
Crytek should've done this themselves inhouse and used the newest version of Cryengine, 5.6.6 as of exactly 1 year ago, Used obscenely high res textures and really pushed the envelope in RT, Physics, Lighting, Textures, Water etc... instead of remastering, Remastering is just an easy cash grab playing on peoples nostalgia.
