So after struggling with the awkward controls for days, I think I've finally achieved a proper analog stick behavior for this game. Most of the problems could be solved with the help of the excellent pcgamingwiki.

Problem:
- Ingame VSync caps the framerate to 30.
Solution:
- disable ingame vsync, force vsync via driver (crimson didn't work for me) or third party tool (D3DOverrider (included in Rivatuner))
- cap fps to 60 via driver or third party tool (MSI Afterburner)

Problem:
- deadzone of analog sticks is too large
Solution:
- use a XInput wrapper () or a DirectInput wrapper if necessary ([url=https://github.com/x360ce/x360ce]x360ce) and raise the anti-deadzone parameter

So now I could play with vsynced 60fps and better deadzones, but the sensitivity of the right thumbstick was still too big. The reason for this is that the sensitivity is somehow tied to the framerate, it's playable with 30fps but not really with 60fps. Sadly there is no ingame option for analog stick sensitivity, only one for the mouse. Well, then why not map the analog stick to the mouse I thought to myself. Said and done:

Problem:
- sensitivity of the right analog stick is too large when playing with 60fps (->too fast camera movement)
Solution:
- get a tool (Autohotkey script) to map the right stick axes to the mouse axes.
- find a good combination of in game mouse sensitivity and the mouse setting of the mapping tool, also set the xpadder deadzone setting as low as possible (see attachment)

I had no luck with autohotkey and couldnt achieve a slow and smooth movement with it, so I tried xpadder (you have to set compatibility mode to vista to use the freeware version with windows7) and it worked! With the right combination of mouse settings in xpadder and Dead Space I can now play the game how it's meant to be played (good sensitivity and deadzone in normal mode and aiming mode).

See the attached image for the settings I've made (results can be different with other controllers of course).

hello, thx for the solutions....

i disabled the v sync ingame and tried to force the v-sync with the amd catalyst and then the radeon pro tool....but both didnt work.....

the scripts are still bugged, and the corpses do still dance like when the ingame v sync is deactivated (both wont happen when i activate the ingame v-sync...which results in wobbly mouse aiming and a 30fps feel)

any ideas where the fault could be?

Forcing vsync via driver didn't work for me too. So forget about that.
I've also tried RadeonPro and it worked. Looking at your second screenshot I see that you've activated the wrong vsync option (this is essentially the same as in catalyst, that doesn't work). You have to go to the "Tweaks" tab. There is the right vsync setting along with the framerate cap. Set VSync control to Always On and Dynamic Framerate Control to 60 (You can also try out Triple-buffering, which may or may not help with mouse aiming). This should solve your problems.

Thanks for this, will give it a try. Does it overcome the mouse aiming deadzone issue? When aiming with a mouse, slow mouse movements are ignored by the game.

Thanks for all the solutions !
It's working well for me :)
For sensitivity of the right analog stick I used your method with JoyToKey.

Concerning V-Sync, on the nvidia panel, there is the option "V-Sync Tear Control" : should it be set to "normal" or "adaptative" ?

No. This is for gamepads only. Unfortunately, I haven't found a way to get proper mouse aiming without deadzones. You could play with the dpi mode of your mouse and the ingame mouse sensitivity setting though. I have no nvidia card, but afaik the Adaptive mode disables vsync if your framerate falls below 60.

Thanks a lot for the explanation ! :)

thx alot for your help i ll try it soon...

love the gog comm :-*

for the dead zones on the joysticks there is a simpler solution. simply turn the in game setting mouse sensitivity higher.
