Re: SWTOR horrendous stuttering.
First up The Intel(R) HD Graphics 4600 is still active in the system, I personally would disable this, otherwise ensure the game is using the Nvidia 970 card
important - select the swtor profile in the Nvidia control panel under manage 3d settings and set the following in the swtor profile
maximum prerendered frames = 1
multidisplay/mixed-gpuacceleration = single display performance
powermanagement mode = prefer maximium performance
if vsynch is enabled set
triple bufferring = on
otherwise if vsynch is off set this to off as well.
Disable the nvidia streaming service for now as well, there is one crash report listed for it, the dwm is listed as crashing a bit as well.
Maybe the reliability monitor will give more details, you can look at this by pressing the windows key and type reliability then select view reliability history
