Could you post the specific system details?
Sure, I got an itel core I5 with 16 G Ram, Nvidia GTX 970 PNY ( yeah, that's true) 1T SSD, a beautiful peace 
What operating system do you use? Is it a 64 bit or 32 bit system? Please open the console when you're ingame (key ^ or ´) and type "report" (without quot. marks), now a report file should appear in the game directory (steamversion: steam/steamapps/common/risingworld). Please upload this file or post the content here 
Apart from that, please try to run the game in windowed mode and disable VSync. Does the issue still occur?
Thanks for the log! I'm really wondering what may cause this issue 
When did you experience this problem on your computer for the first time? Did it also occur prior September (with the previous Nvidia driver)? Is it really a framedrop when looking around (so the game stutters), or is maybe only the mouse input interrupted?
Are there any other programs running in the background? Did you already restart your computer (sometimes there might be performance issues for no reason which can be fixed by a clean restart)?
hes got OS: Windows 8.1 (x64) this is strange i would think it could be driver problems oO his settings are way to low and specs are fine
The part about the background programs was more related to capturing software, or other programs that hook into the game
It's a really strange issue though... so it does only occur when moving your mouse? When you're just walking around (keeping the mouse steady) the issue does not occur?
You could try this (to make sure no errors occur in the background): Go to your game directory, open the config.properties file with a texteditor, set "game_debug_console" to true, save the file and start the game. Now load a world, walk a few steps and move your mouse (to reproduce the problem), now alt-tab to the small white debug window, copy the content and please paste it here or on http://pastebin.com (and provide the link here).
Alternatively you can eventually try to downgrade to a previous driver version, sometimes the newest drivers can cause graphics card specific issues.
Thanks again for the log, everything is fine there, so no errors in the background that could cause this issue. About my previous question, does it only occur when moving the mouse? What happens if you just walk around, without moving your mouse? Does the issue still persist in this case?
About driver rollback, here is an instruction on how to do it: http://www.nvidia.com/object/driver_rollback.html
Unfortunately I have no clue what's causing this issue, I haven't seen it before, and I doubt it's caused by the game (of course I can't say for sure). But I found quite some topics via Google where people had similar issues in other games. In some cases it was caused by "Intel Technology Access Service" for example, killing the process solved the issue (find it in your taskmanager -> processes). In other cases it was related to malware, or the mouse/mouse driver itself (maybe you can try to use another mouse?).
