Shadow/performance thread.

Seeing as though the issue with performance seems to lie with shadows, an acceptable trade-off that has removed stuttering for me is to change iShadowMapResolution to 1024 then fDirShadowDistance to 4000 and finally fBlendSplitDirShadow to 500. This will lower quality but remove resolution pop-in (the radius shadows change detail at).

If anyone knows how to add blurring to shadows though feel free to share.

I'm pretty happy with this.

iBlurDeferredShadowMask=22

iShadowMapResolution=5192

fShadowBiasScale=1

 

iShadowMapResolution=5192?? How? What's the trade-off? I can only use 1024 with a GTX 1080 and i5-4690k.

 

Also you would have had to add iBlurDeferredShadowMask as it isn't in the .ini by default.

iShadowMapResolution= has been sitting on 2048 for ages with me. First with an MSI R7970 Lightning and now with an MSI RX470 GamerX 8GB card. CPU is an i7 3770K.

Do you get slowdowns? Stutter in Boston areas? I did with it at 2048 and I'd much rather ugly shadows than that.

I had and I did. Those went away when having bought and installed my 8GB GPU.

 

Am using both ENBoost and ShadowBoost, by the way.

Lucky you. My 8GB GPU can't do that. I don't use ShadowBoost. Too much pop in. I have my shadows set to 4000 and I have removed the resolution change upon getting close to them. Permanently blurry but unchanging is better than following a line on the ground.
