Mouse Control Jerky

[JookyThingy]

Hi, this is my first post here. So I guess this makes me a noob.

 

To the point. Find a spot where turning will be jerky. Then turn slowly to find the exact point where the jerk occurs. Turn back and forth over this point and notice that the jerk occurs only one way, not both ways. Notice that the jerk occurs at the same exact point every time, all the time. Rinse, repeat. This is the problem with jerky mouse control. I've seen it being described elsewhere but apparently not accurately enough. Otherwise, there would be a solution already. Or at least it would be a "known problem" in any case. I've seen the same problem with Fallout 3. The problem doesn't occur in any other game. It's not related to mouse acceleration. It's not related to mouse speed. It's not related to the controls themselves. It's not related to my machine or its possible lack of performance: It has plenty of juice. I've fooled around with pretty much every ini parameter I could think of to no avail.

 

Did anybody else notice this problem? Did you find a solution?

 

Here's a description of my machine:

 

Intel I5 750

Gygabyte P55A-UD3

4GB (2x2) DDR3-2000

BFG GTX285-2GB

Corsair X128 SSD (main drive)

Western Digital Caviar Black 640GB (secondary drive)

Asus VK246 LCD

Logitech G9x mouse with SetPoint 5.20.40

Logitech Slim Keyboard no SetPoint

Antec TruePower 750w

 

As we can see, it's highly improbable that the source of the problem is a lack of performance from my machine or any of its components. And considering that the problem doesn't occur in any other game, and that it occurs in a precise fashion at specific predictable points in the game, I can only conclude that the source of the problem is the game itself.

I'm not sure if this is like what you're experiencing.

 

When I first entered the sewers in near camp Macarren(?) I had this herky jerky mouse point of view motion, it also occured in another area (can't remember where). i downloaded the graphics card .dll (Nvidia version) from the FONV nexus and it fixed the problem.

Though, I don't recall if it only occured one way like yours, sorry.

 

hope it helps.

 

 

Cheers!

It occurs at the gun runners and at the medical clinic and many other fast travel spots. I did not notice the problem inside. Maybe it only occurs outside on the main map.

 

I read that the dll fix is intended to improve overall performance in case the machine can't handle the new face geometry. I don't have such a problem. Overall performance is great with every settings to max and beyond. Reducing setting to medium or lower or even turning some of them off doesn't fix the problem. In fact, doing this makes the game so much more smoother that the problem is now made that much more obvious when it occurs. Nevertheless, I'll try the dll fix.

It looks like stutter to me.

It looks like stutter to me.

Well yes, stutter is exactly what's happening. But there are different kinds of stutter, caused by different things. This stutter in particular occurs with absolute predictability at always the same exact specific points. It's predictable, it's reproducible, and it occurs at the same points all the time, every time. Does it still look like the kind of stutter you mean? Does it look like any other kind of stutter that is already known to date: Micro-stutter, loading stutter, lack of performance stutter, etc? This one would be called predictable stutter due to its behavior.

 

It's not micro-stutter because it's not related to time but to position. It's not loading stutter because everything is loaded yet the stutter still occurs. It's not lack of performance stutter because my machine can handle pretty much everything I throw at it set at max settings and beyond. This stutter is something else. It could be due to some flawed loading algorithm that unloads and reloads specific materiel back and forth as I move the view back and forth, maybe as a result of the limited buffering capacity of the engine. I don't know, but I know it's a different kind of stuttering than the ones we've been used to. It's not new since I noticed it in Fallout 3.

[hafiz22]

how do you fixed the problem?

[JookyThingy]

I didn't fix it, it's the latest update that fixed it.
