graphical issues not present at game's release

[endoskeleton]

there seem to be a number of broken effects on current builds of windows 10 and with current geforce drivers. the raymarched volumetric lighting effect is broken, where it wasn't at release date on windows 7 or whatever i was rocking at the time

post process bloom and post processing in general seem to be incomplete/not working quite right but could be in my head

pcgamingwiki has this game's lack of flashlight shadows and per object motion blur as a feature that was always missing from the pc release. though my memory is faulty i seem to recall at least flashlight shadows in the pc version once (i've replayed this game a bunch but then i own the 360 version too)

maybe some of this could be fixed through a simple windows compatibility mode modifier on the executable. but any help would be useful since pcgamingwiki is lacking here

Have you tried to patch the game or look at Nexus mods for it?
