Jittering when moving mouse

[LoTekRabbit]

I am getting really horrible jittering when I am moving the mouse. Either when looking around or straffing.

I have tried it with and without V-Sync. Double and Triple buffer. I have also tried turning Multi-Core off.

That's... really weird. Have you tried enabling/disabling raw mouse input?

(Sorry for the late response)

Yup and it's doing the same thing.

- I've tried 3 different mice. Deathadder 2013, Roccat Kone, and CM Spawn.

- Tried using my secondary monitor to see if it was a monitor issue

- I took my 780 out and tried it with a 680 + a couple of different drivers.

- I removed all of my overclocks

- I tried turning Hyperthreading off

- Moved files over to Samsung SSD from Corsair just to see if it was the SSD

- I don't think it's a Source issue with my computer because CS GO works fine and I even re-downloaded Portal 2 just to try a different Source game and it too is fine.

- PS: I tried capping my framerates below the refresh rate of 60 and I noticed it's far, far worse. I'm wondering if using a 120 hz monitor would make the issue go away. But then again you're finding it really weird and no one else has commented so I feel like there is something going on with my rig and the game.

If I use WASD it's fine but as soon as I move around with my mouse the screen jitters so bad that it's unplayable.

Any other ideas? =)

I honestly am at a loss. We had a similar issue with the Mac port and it ended up being an internal issue in the code but this isn't present in the Windows version... I'm really puzzled about this.

If you have a moment maybe you could try copying over 'engine.dll' from Portal 2/bin/ to The Stanley Parable Demo/bin/ - but I'm not sure if this will work & if this will solve the issue.

[LoTekRabbit]

Did two things:

Tried copying over the .dll and it doesn't resolve the issue but the game does work, just crashes if you press 'escape' to get into the menu.

The second thing I decided to do was OC the monitor via Precision. So I oc'd it to 70 hz (couldn't get passed that) and it felt like it jittered less. I wasn't sure if it was a placebo so I then set it down to 50hz and it was noticeably worse vs the 70.

I find it strange that two seperate GPU's and monitors would have this issue. Any idea why increasing the refresh rate and thus framerates would start to smooth it out?

[Gran PC]

Sorry - I have no idea what could cause this at all. Unfortunately I don't have a computer with 2 GPUs (I'd rather say I have a computer with half a GPU) so there's not much I can do to reproduce this locally. I'll let you know if I come up with anything.

[LoTekRabbit]

No problem bud, thank you for taking the time to help me out I really appreciate it.

I'll see if my friend can bring his 120hz monitor over later today so I can test it out. I'll post the results here once I do.

[Gran PC]

Good luck - let me know if it works!

if the "jittering " mean you can't get V-Sync to work just force it in the nivida settings not the game.

Did you ever think to stop shaking your hands from all the excitment?

No jitter with the 120hz monitor. It's incredibly smooth.

It's really bizarre but whatever lol. I always wanted the Asus 144hz monitor for FPS games so I think it's a good time to pick one up.

Haha geez, that's the weirdest issue I've heard of.. Hopefully I'll be able to reproduce it some time soon ;)
