Stuttering Zombies?

[CriticalComposer]

Is there a way to stop the stuttering zombies? Their movement isn't fluid at all and it takes me right out of the experience. I also have the problem with co-op partners, their movement is very sporadic and doesn't look natural.

same here.....mainly ones that are near you.....but not always consistent....

Sounds like you are having performance issues. Whats your FPS? Any frametime spikes?

[CriticalComposer]

I don't have any hard numbers but the world, the camera, my hand movements, the lighting, and the movement of objects like switches are all smooth. It's only the zombies. Stuttering might not be the right word because that would imply framerate stutter. It looks more like a glitchy kind of stuttering. Where the animation of the zombies is constantly snapping between two different states/cycles.

Step one for pretty much all troubleshooting is to update Windows, reboot, and check for updates again after the reboot. Once that's done, check the video card manufacturer's website for update video drivers. If your software is not up to date, then you might be fighting a battle that never existed. After that, I would try messing around with your in game video settings, such as lowering stuff to minimum. If that doesn't fix it, post again for further diagnostic procedures.

By the way, what are your specs? CPU GPU and RAM.

I'm well aware of how to troubleshoot stuff and have tried all of the usual stuff -- drivers, updates, reboot, etc. I've messed with settings in-game as well as SteamVR settings. I know you need to ask just to be sure -- you gotta get that foundation and starting point out of the way to help troubleshoot -- but yeah, I've done that. Specs are:

CPU: Intel i5 9400F
GPU: Nvidia GTX 1660ti
RAM: 16GB DDR4
Storage: SSD

Funny enough, the "special i7 enhancements" toggle in-game improved the stuttering animations a little bit. And I forgot to mention that this issue happens with co-op player animations as well. I've pretty much stopped playing but I'll see if my computer can capture some footage of it.

Ya, gotta cover the basics. Some people don't know what "PC specs" means.

Anyway, your hardware and software sound OK. I suppose you could always "verify game files", but I doubt that will help anything. I really think the next step is to check the actual performance of the game. FPS and Frame-time. I use an app to do this. Its locked to my left wrist while in game, and uses graphs. Its great for seeing how things are going.

Oh, that brings up something I should have mentioned (VR is new to me so I hadn't considered it). I'm playing on a Quest 2 so I suppose it could be an API thing. I believe Arizona Sunshine doesn't have Oculus API support but I don't know if that would affect the zombie and co-op partner animation. With that said, I can't use fpsVR since I can't pin desktop apps to my hands like I can with a native PCVR solution. I can run Nvidia's FPS Overlay though and I can have someone else watch that on my monitor while I'm playing.

[Zombie Killer]

What you really need to check is the FPS and the GPU/CPU frametimes.

For me, the biggest problems I have ever had on VR is GPU frametime spikes.

FPS will not detect GPU frametime spikes.

What stopped the stuttering for me and it should work for you too is to reduce the game's resolutions in SteamVR. Lower the resolutions numbers.

[Prontius]

Disappointing if that's the only way to fix this. I think I'm just gonna stop trying to make this game work if the devs didn't try to optimize it.

[CriticalComposer]

I just bought the DLC so I'll be jumping back into this next week. I'm really hoping the resolution fix works!

Current VR does a lot of trickery to prevent you from getting dizzy.
Stuttering might mean low FPS at the source while software in the headset is interpolating a new view from old data, which works for the static world but not for moving objects.
Do your virtual hands move fluidly while this is happening? if not, it's FPS.
