I did some tinkering with Oblivion and its array of helpful mods today, and thought I would share some of my discoveries.
All of these require OBSE
Oblivion Display Tweaks = this helps with microstutter and other things. It is compatible with OSR, but only if you Turn off bReplaceGetTickCount in Oblivion Stutter Remover's .ini file.
Oblivion Stutter Remover = of course.
OSR Optimized .Ini File = Is just the .ini for OSR, and has the bReplaceGetTickCount disables, among other tweaks.
Engine Bug Fixes = A bunch of bug fixes.
SkyBSA = Changes the way Oblivion puts BSA assets in your load order to act the same way Skyrim does, namely by no longer mucking with timestamps, and just going by your load order.
