Well the original uncompressed size was at 64Mb only, engine fixes when you activate the setting doubled that to 128Mb which was more than enough before the .esl or .esp-fe files where a thing, nowadays more and more people with massive load orders hit that barrier also. It's the final barrier that's still in place for Skyrim modding. To be honest only people like you and me with crazy load orders hit it, probably not a very big percentage of players. I don't know if it's technically possible but I suspect it is, to raise it to 256Mb, but the engine fixes author isn't been active for some time now and if he ever updates I suspect it's going to be for the latest Skyrim AE version only, which wouldn't help in my case since I'm staying put on 1.5.97. There is no way I"m going to upgrade a load order of 4k+ mods with 251 esp/esm"s and 2933 esl's I worked on since 2016 lol, would take me months or maybe a full year, not going to happen. Edit: BTW, I thought I was crazy but a guy on reddit claims he hit another barrier: 255 esp/esm + 4096 esl's lol I wonder how much Mb his new game save is. :D I tried to contact aers, but he is elusive :) . I gave it another try at GitHub, we will see. Unfortunately i ran into some problems setting up Visual Studio with SKSE, probably because the description is from 2019 ... I think, the main problem for most of us is not the amount of mods, but the time we play. When i start new, i have 8 mb or something like this ... ok, with dyndolod it ist probably closer to 20 i guess, but nothing crazy. Edit: BTW, I thought I was crazy but a guy on reddit claims he hit another barrier: 255 esp/esm + 4096 esl's lol I wonder how much Mb his new game save is. :D -> wtf is he installing just everything ?
