It is very possible that the stutters have more than One cause.
Correct - FD have admitted this:
We're finding the issue equally frustrating. A low level fix will be added in 1.3 to address one possible cause for microstuttering and we're continuing to investigate other causes.
I think we need to tread carefully when testing with the training scenarios, we don't know if they work the same way as the game. Sure, they use the same .exe and the same set of files so maybe it's valid but just a word of caution that's all.As I said earlier If I go to the Combat Missions direct from the launcher, everything is silky smooth.
Understand this can happen, but to repeat myself it is not a stutter caused by the graphics card
See above. One cause of stutter may be caused by graphics drivers. As I said previously, the note in the 1.3 changelog referred to driver issues specifically with regards to micro-stutter.
Has anyone tried disabling hyper-Threading in their bios?
Lots of people. Some people in the past have claimed that it "helped", as well as turning off core parking. I think collectively we have tried everything that is possible from the user side, either to troubleshoot or to find ways to reduce the stuttering. I have a list of 44 things (depending on how you count it) I have tried over the last 5 months.
As I said earlier for me it is related to network traffic in some way.
This is my suspicion, too. The stuttering has been noticeably worse when the servers have been, as FD puts it, 'issues detected'. Tonight everything seems stable, and the stuttering is practically gone.
Yeah the more I play the more I wonder if this is the cause of one or more types of stutter (NOT all of them). Server load more than network traffic. When I get stutter I have been glancing at the Ctrl-B OSD and there has been no network traffic. I have noticed that a) stutter seems worse in a system that has lots of astronomical bodies (especially asteroids but also planets, moons etc.) b) stutter seems worse in a system where the traffic report shows a higher number of player ships (including playing in Solo) and c) worse when there a large number of NPC ships e.g. conflict zones.
NB: just to be clear, the stutter when approaching planetary bodies is caused by a resource loading issue, hence the "warming up shaders" change in 1.3, and can be treated separately.
