I'm also still trying to get a handle on what iShadowFilter does, what I do know is if its 0 then I don't have any shadows and if I set it to something like '8' in whiterun the whole map gets a rather grey sort of super shadow across it, oh and '8' completely slaughters FPS if I try to go inside of dragonreach.ĮD: Btw that secondary & primary stuff: They tie into the range defined by fShadowLODStartFade, I believe primary is everything from 0 -> startfade and secondary is holding startfade -> shadowdistance/interiorshadowdistance. Still no clue on that splitcount, stupid shadow engine! IShadowMaskQuarter - The higher the setting the more it softens the outdoor shadows.Īt least this is so far my understanding of how the two work. IDeferredShadowMask - The higher the setting the more it softens the indoor shdows. 1 its got most of the feet but its also now drawing *alot* more shadows due to all the little short objects throughout the game world and is overall a lot more taxing on the shadow engine.Īmanda Furtado Posts: 3454 Joined: Fri 4:22 pmįound from that other thread with the guy talking about turning off quartering. Example: at 0.25 my character's shadow doesn't really include his feet, its got from the ankles and up but not the feet themselves, meanwhile if I set the scale down to like. Ie the lower you set that the smaller the minimum height of an object needs to be before the shadow engine will include it and the higher that value the wierder shadows of regular sized things like characters look since the shadow only starts at that height. Oh but one you may as well throw in there is the iShadowBiasScale, which is the method by which you can tell the shadow engine to ignore drawing shadows on things beneath 'x' height. The one I'm completely in the dark about is what this does: But yah I don't yet have a clear understanding of their relation in this particular puzzle. However if I were to say drop them both to 1024 my game slows down often and the shadows on a whole look way blockier. Also from tinkering I found if you leave those values too low its detrimental to performance, I've currently got them both at 4096 with a shadow min distance of 1500 and max of 5000 and the shadows look like they 'should' vs the rest of the values like deferred blur etc. Does anyone have some information on what they do?Įnie van Bied Posts: 3350 Joined: Sun 11:47 pmįrom tinkering with these two value seem to represent the total space allocated for that close ring of higher def shadows vs the secondary larger ring that extends out to the Shadow distance. I can't seem to see any impact from those. IShadowMapResolutionSecondary=512iShadowMapResolutionPrimary=1024 However, the ini also has those two lines:
SKYRIM LE SHADOW INI UPDATE
I feel it makes shadows a bit more "agitated" while moving, which is why I prefer iBlurDeferredShadowMask.įShadowBiasScale=0.15: Determines how high an object has to be (relative to the lightsource?) to cast a shadow.Īnd, from the display section in Skyrim.ini:įSunShadowUpdateTime=0.0000: How fast the shadows move when sun position is updated (0 means they jump, reducing jittering)įSunUpdateThreshold=0.5: How often the shadows update relative to the sun movement. Lower = less detailed I think, with 0 disabling indoor shadows. IShadowMaskQuarter=4: Impacts how "crisp" your shadows are. I leave it at 2048 as higher values give a significant loss in fps for indoor scenes. So: low values mean good looking shadows and good performance but as you don't see them far away it will look strange when they appear while moving.Īlso very important, controlls the shadow resolution, therefore the overall smoothness.
SKYRIM LE SHADOW INI PC
Lower values will give you much better performance, as it means the pc has to calculate less shadows. Larger values obviously mean shadows visible further away, BUT it also means the quality of the shadows will be reduced.Īdditionally it can have a significant impact on performance. Probably because lowering it will usually mean more shadows being rendered, instead of nicer ones (see below).Įxterior shadow distance.
Interior shadow distance, doesn't have a overly strong effect for me. This setting will blur your shadows, masking the low resolution of the shadows a bit.
