Have been running 0.200 until this update with these settings which work well for me and now keep TESV ram under control:
ExpandSystemMemoryX64=true
ReduceSystemMemoryUsage=true
DisableDriverMemoryManager=true
DisablePreloadToVRAM=true (false for 0.200)
ReservedMemorySizeMb=360
EnableUnsafeMemoryHacks=false
Peak RAM usage TESV.exe 906MB, enbhost.exe 1896mb, VRAM maxed at peak but no crash, running nice and smooth 50-60 fps, next to no stutter
Tests with updated v0.201 (vsync enabled)
With above settings, stutter much improved, still get 30fps frame drops on some scenes:

However if I turn off DOF (K ENBs) the FPS drops are nearly all gone and stutter much improved

Runs nearly like v0.200, turning off ambient occlusion as well gives some small further improvements 2fps average on same run
Keep up the good work Boris!
