dashiichi: Some things to check. If you have Mouse Smoothing enabled (not 0) in the general settings then try setting it to 0. When I had it on, the game would outsmart itself and I'd have very jerky motion looking to the side. Also try turning off Motion Blur and/or Terrain Tessellation if you have either enabled.
In your ...\No Man's Sky\Binaries\SETTINGS directory, make a backup of TKGRAPHICSSETTINGS.MXML. Open the file and look for
<Property name="NumHighThreads" value="1" />
<Property name="NumLowThreads" value="2" />
Change both values to "0". That tells NMS to hog all CPU resources that it can get its hands on. That's not being nice to other applications but playing NMS just has to take priority! ;-)
NovumZ: Thanks so much!
Grats on +5 :)
It helped with movement response and is less choppy, wonder if Gsync is causing this.
What each numbers in values exactly represent if you don't mind me asking.

As I understand it, the HIGH and LOW refer to how many high- and low-priority CPU threads that NMS will limit itself to. The default values (again, AIUI) were set to 1/4 of the CPU's available threads for high priority and 1/2 for low priority. That allows NMS to "play nicely" with the other applications on the computer. Setting either or both to 0 allows NMS to grab as many threads as it can.
However some discussion on reddit seemed to indicate that HIGH refers to the number of physical cores permitted and LOW to the number of threads. Very confusing and the discussions on reddit didn't seem to come to a firm conclusion.
As long as you do keep a backup of your original file, it's safe to experiment a bit. Different setups do seem to have responded in different ways. So, you could also try setting HIGH to the number of physical cores in your machine and LOW to the number of virtual cores (if you have hyperthreading enabled). On my box here, that would be NUMHIGHTHREADS set to 4 and LOW to 8.
As far as I'm aware, Hello Games hasn't explicitly documented how this works, so some experimenting may be in order. Again, as long as you have that backup I don't think that you can hurt anything permanently by playing around with those two settings.
