First, thank the gods for S.T.E.P. and all the dedicated people here that offer their time freely to make it available to an undeserving soul like me. Over the past year I’ve installed Skyrim using the S.T.E.P guide 12 times on 3 different machines and 4 different versions of Windows. My problem is some settings in skyrimprefs.ini are changing, seemingly at random, specifically; iMaxDecalsPerFrame=250 iMaxSkinDecalsPerFrame=100 change to 800 and 250 respectively. First thought is user error and the first couple times I edited in notepad but the last several times I’ve edited only through Mod Organizer. Maybe a senior moment since I am at that age but it has happened too many time now. Knee jerk reaction is Steam is overwriting the settings but this does not seem likely with Mod Organizer storing the profiles as it does and on a dedicated game SSD, plus I mostly play in offline mode. If Mod Organizer is changing the settings I can’t figure out where its getting those numbers. I’ve searched all of my connected drives files and compressed files for the text “iMaxDecalsPerFrameâ€. All the instances discovered were iMaxDecalsPerFrame=250 or much lower (default settings). Next I thought it might be some MOD changing the settings through SkyUI/MCM so I started new characters with some mods that I suspected not loaded, but I still have the problem. I hope somebody else has experienced this problem and can point me in the right direction. This has happened on S.T.E.P. Core and a slightly pruned Extended on a few different profiles. To add to this a few days ago I changed; fSplitDistanceMult=1.5000 to =2.0000, but when I opened my skyrimprefs.ini file today to change it back I found it was already at =1.5000. I thought I must be getting senile but then I saw the other two settings were at 800 and 250 again. I’ve never changed this setting before so it might be coincidence, but I doubt it.
