Jerky graphics in cockpit when moving mouse

[Etsija]

I have a Vista32 and a 1920x1200 monitor, and I am also using TrackIR3 to view around the cockpit. The BS graphics are beautiful and everything is running smoothly, but I do have one very annoying problem:

 

Sometimes when I start moving my mouse around the virtual cockpit to click on things, I get horribly "jerky" graphics. I mean the screen just starts this horrible shaking effect, and in result, I can't click on anything, since I can't point my mouse to the right direction. Whenever I stop my mouse movement, it stops and I can once again smoothly look around in my cockpit with my TIR.

 

This does not happen all the time, also sometimes after I fly for a while the problem disappears (but not always). I feel that this could be some sort of "display sync" problem...anyone have a clue as to what I should be looking at?

 

(My screen is running on its native resolution in DCS:BS at the moment.)

It happens something similar to me sometimes but I don't have trackir. In my case there are two zooms "colliding" from time to time: mouse wheel and saitek rotary (asigned to zoom). But in my case it's easy to fix.

I didn't have any 'jerk's' running DCS: Black Shark maxxed out till I bought TrackIR as soon as I installed it the frame rate was all jerky when looking around.

 

I am going to post on the Natural Point forum and see if there is a way to deal with this.

It is probably because your mouse-look is active and is conflicting with your TrackIR

Simple solution, press LAlt-c to release mouselook (and get that little yellow crosshair showing).

Please note that there is a known bug that causes the mouselook to be active together with the little yellow crosshair when starting a mission (or returning from the esc-menu).

Oh, I didn't know about that bug - I certainly have not enabled mouse look by myself (obviously, because I'm using TIR for that), I always have the yellow crosshair showing, so it could be the bug showing. I'll try out that CTRL-C trick tonight. Thanks for the tip.

RCtlr C is cockpit door? Nothing on LCtrl C? I see from the Keycard that someone made where it says LAlt C "Tgl Mouse clck"? I assume that's what you mean??

Yes the correct key kombination is LALT-C. Seems that I needed to click this twice: first time I did LALT-C, the mouse pointer (+) disappeared, second time I did it, it reappeared again, and now the mouse pointing started to work together with TrackIR, without the "jerky" graphics. So it seems to be because of this bug Boulund described. I need to do this trick every time I get the jerky graphics, however I can live with it now that I know what to do.

 

I do hope the bug will be fixed in the batch, though.

 

Thanks for the help, Boulund! Everything seems to work smoothly now.

Sorry for giving the wrong key combination, fixed it in my post.

 

The reason for the crosshair first disappearing and the reappearing is that the first time you press LAlt-c you go into mouselook-mode, and the second time you go back to (what should have been there from the start) the "mouse-interaction-mode" or what to call it.

 

Great to hear it fixed your problem
