Wow...old topic now, but just wanted to say thank you striker and melthorn for hitting on the same crazy issue I have. Been modding for years as striker has and have followed striker's posts quite often...full of good stuff from good experience! Oblivion is one of those poorly optimized (no really?), only uses one core, games that doesn't like me to ride a horse at all! I can go for a long time on foot, but just let me get on horseback and BAM! The engine just chokes with mods and fast moving cells. Bethesda makes some of the best of the best, and Oblivion is a great game...... on foot...lol..even with the occasional crashes. Love to hear young modders wonder why it does this or that with NMM...but even manually installing or with wrye, as I do, it is still the most aggravating of all the Beth wonders......happy modding :teehee:
