Hello there, I'm experiencing the same issue addressed in the thread. Although I'm an NMM user, I have configured it to run custom skyrim launcher using skse_loader with -forcesteamloader argument. However, the memory tweak still won't work for me. I have also tried launching skse_loader directly with -forcesteamloader in a shortcut, neither did this help. My preallocated memory is still 256MB for the first block: Below are my skse.ini settings (I have checked it is not .ini.txt): and here's what I get from C:\Users\Lingyi\Documents\my games\skyrim\SKSE\skse_steam_loader.log As far as I know, this memory patch is included in 1.7.1 version of skse. Could anyone help me with this ? I have 64-bit windows 8 OS and I'm currently using Realvision ENB which use enbseries 262. I realy hope I could get this memory tweak to work since I have been running about 150 mods and every once a while it will run above 256mb memory Thanks ahead for any inputs on this P.S. for the time being, I will be using SSME and it does successfully tweaked the memory, but I'm still looking for a skse.ini solution since this is likely the method that'll be maintained in future.
