The console version doesn't look as good as the original, and any mid-range PC can max the original easily; not to mention the PC version has a whole load of mods for both visuals and performance.. why would you want it?
as i said in my first post
1- The Pc version of te game runs on the cryengine 2
the game has a worse performance otimization, and lacks lots of techniques that cryengine 3 have
sure there are lots of mods for the PC version, but most of them are just texture packs, unrealistic tod's (impossible to find a good one today)
there is a guy on crydev that made a whole new shader for crysis, but it have lots of bugs, unrealistic parameters and terrible performance
The remastered version, could make use of the amazing ce3 redering techniques, such as anamorphic lens flare, Gi, bokeh dof, all things that crysis Pc version lacks and cant be done with mods
and the performance otimization would be another important thing, sure a GTX 680 can max the game, but with inconsistent game performance, due to ce2 limitations.
@ESFER25, i think that tesselation can't be aplied in the original crysis assets, and tesselation is one of the dx11 features that is in it great part, pure marketing.
sure its a nice tech, but with the awesome crysis models and maps, tesselation is the technique that has the lowest impact in the game visuals
tesselation should only be implemented in a game, after that all the Tod's, models,textures,shader quality and light efects are already in its limits, cause any of them have much bigger visual impact
crysis 2 DX11 patch is an good example. they aplied tesselation in a lot of things, causing a massive performance hit for a litlle visual gain. if they have made a better tod for the levels, a proper texture patch, and real time reflections, the game would look better than the original dx11 patch, and with much better performance
the DX11 OMG TESSSELATION viral effect made lots of people put hype on it, and upgrade their systems for basically no visual gain
PS: sorry for my english, i really tried my best
if you didnt undertand something, please ask me and i will try to rewrite it
