After updating to patch 1.3 my fps got even better With patch 1.2 I had 10-15 fps in Markarth using the same settings, with patch 1.3 I now get 20-35 fps in Markarth! If anyone with a dual core processor reads this, I recommend updating to patch 1.3, whatever they did to increase performance on dual core processor works wonders. Don't even need the fps limiter to get rid of stuttering now either patch 1.3 has fixed that for me, probably another effect of the increased performance for dual cores. Apart from the awesome increase in fps, I haven't ctd once and the patch 1.3 eliminated my micro stutter that happened when running around in 1st person view. Only issues I have noticed is that when I zoom in with a bow, the y-axis becomes incredibly sensitive whereas I can barely look around because the x-axis is sooooo un-sensitive (however this was there before the patch, I just thought 1.3 was supposed to fix it).
