I keep having CTD's after 10 to 15 minutes usually. The only thing I've noticed that is constant is the bstask number is usually above 100 when this happens. I don't know what bstask refers to but that's the only thing I've noticed. My operating system is Windows 10 Professional 64 bit My CPU is an Intel i5 4570 I have 8G memory I have a Nvidia Geforce 750 ti Video card According to Task Manager Oblivion is using between 700Mb and 1Gb depending on the number of mods activated with a total system memory load of 3 to 3.5 GB According to Wrye Bash Active Mod Files: Oblivion Reloaded is installed also at the moment. When it is not installed my BSTask reading can get into the 300's without CTDThe same is true when using Qarl's Redimized textures or Ultimate Landscapes
