Microstuttering/Input Delay Fixes to try

Obraxis

Hey all - we've been getting reports of Microstuttering and Input delay still - even after some fixes went into 253.

Could you please try the following and report back if these fix your issues, or not:

Open Console

Micro-stuttering Fix

---

(try switching see which is best)

r_mt true/false or r_mt 1/ 0 (Thanks @Tarrog)

Disable Physx in main menu


Input Delay Fix:

---

Turn on mouse accel, disable raw input
Then
Turn off mouse accel, turn on raw input

Input delay should be fixed (Thanks mf-)

There is an incompatibility with Mumble/TeamSpeak OVERLAY which can cause framerate drops. Please disable for now.


**UPDATE**

Another thing to try:

Create a new NS2 Shortcut.

Right click on it, hit properties.

Apply the following settings:



Run NS2 from this new shortcut. See if your FPS/Input Lag has improved.


Thanks everyone!

r_mt doesn't effect the microstutters for me

input delay fix works however

OuchOfDeath

I don't have micro stuttering with DX9, only with DX11 (which I don't use as it's slower) so I'm not gonna comment there.

The input delay fix doesn't work. It lowers the input lag, but it's still there. Turning raw input on also throws my aim off as I'm used to playing with it off (I use windows' mouse accel), so it's not much of a temporary fix.

Seb

I don't get stutter with DX11, nor input lag. Is anyone similar to me?

Thanks everyone!

I'm suffering from both Micro-stuttering and Input delay. I tried fixes for both but I see no improvement. In addition, I'm seeing insane FPS drop in combat - often it will go from 50 FPS to 5 FPS or below.

Can't seem to fix the stutter, did a quick profile capture and the "RenderThread::WaitForTasks" was spiked really hard during one of the freezes.

Just copypasta from reddit.

FIXED: Stuttering
CPU: i7 3770k GPU: Gainward GTX 680 Phantom

My Setup

• Resolution: 1920x1080
• VSync: OFF
• Physx GPU Acceleration: ON
• Everything maxed out.

First off all I deactivated multithreading in the console by: r_mt 0 then, activated Physx GPU Acceleration in NS2 in the Options.
Go to desktop rightklick for Nvidia Settings then ---> SETTINGS and reboot the pc, and try.
It worked for me. But I'm still sad that it doesn't work smooth like butter but I think UWE is working on better optimization of performance...I hope

Dictator93

I would like to point out that the GPU PhysX option in game does not seem to work. If you use the Nvidia Inspector program and turn on the overlay for PhysX it states that the game is not using the GPU for physX... but rather the CPU.

Enabling Vsync/triple buffering also seems to make the game feel a lot smoother for me, although it doesn't help inputdelay.

Ghosthree3

Switching from fullscreen to borderless gave me less hitches, but be careful because alt tabbing in borderless causes a memory leak at the moment which will eventually crash the game. Worth it for smooth gameplay though.

dePARA

I play around with the different apis (dx9,dx11 and opengl) in combinations with the different modes (windows, fullscreen, fullsceen windows) a bit.

result:

DX9 and DX11
Feels the same on every mode, it seems the game didnt switch beween them. vsync didnt work.

OPENGL
VSync is working and it feels smooth with the typical inputdelay.
Different modes working also.

Try opengl on windows modes + force vsync via graphics card setup panel:
No inputlag and smooth @ the cost of one scanline in the top area of the screen. (strange graphic bug)

Both fixes didn't work. They simply don't give any change. The input delay stays no matter what i try.
As far as micro stutters go, in-game i can have like 80fps but it feels like 15.

Maybe this is the problem? He says NS2 is not really running true Fullscreen:

I did not have it, now I have it.

It does, and I used it before, but I have found out it introduces even more input lag, so I have disabled it.

The input lag and microstuttering is apparently caused - at least in part - by using aero in windows - windows doesn't allow the game to automatically use the resources properly, even if it's full screen. The workaround is to find the executable and "disable desktop composition" in it's file properties here;

C:\Program Files (x86)\Steam\steamapps\common\natural selection 2\NS2.exe

Thanks to Samusdroid (Orphan Black) for picking up on this ! :-)

That solved most of the problem for me. Full props to Orphan Black.

Kamamura

Well, I have found out that the culprit was the PhysX support option I turned on out of sheer curiosity. Now it's fine again.

SamusDroid

Turn desktop composition off in the exe's properties.

Eucomolhamas

Phew! Gotta say I got a little worried when I went in game and pretty much couldn't do a thing.

Gonna try out the fixes tomorrow and hope for the best :P

DC_Darkling

PhysX support on GPUs is for nvidia only.
Do not enable it unless you have a nvidia card.

If you dont have it, it will run on the CPU.

Right click on it, hit properties.

I did the mouse accel on/off and raw input off/on and also did the disable desktop composition.

My mouse input lag is all but gone now.

Seems to have helped the mouse lag. AMD Crossfire is still broken, and the one video card that is working is running about 20 degrees C lower than before. Game is unplayable still.

@Obraxis, the aero fix seems to have worked for at least one person I know with the problem.

Mouse

That fixed it

(it also works for most of the rendering problems I've been having with the editor)

Obraxis

Yeah it's not the most elegant solution, but the current theory is that SDL is fighting Windows Aero for resources, so if you disable Aero NS2 get's priority again.

Max and Dushan are on the case

Eucomolhamas

That shortcut thingy fixed the stuttering (except I did it for the ns2.exe itself) but I couldn't fix the mouse acceleration issue with the suggestion posted here, any other ideas?

Ghosthree3

You did the on/off switch listed in OP? That + no aero should work.

@Ghosthree3 Yeah, I meant the on/off way with that. Tried it a couple of times with no effect.

Heavenfall

I tried the disabling Aero and it greatly reduced input delay, it is barely noticeable now for me. Massive FPS drops in combat remain very bad however.

This had no perceptible effect on input latency for me.

I've got a Geforce GTX 690 and, when I run the game with multi-GPU enabled, I find that input latency is barely perceptible. If my frame rate is over 120 FPS, it seems pretty responsive. I feel like it might be marginally higher than other games but still acceptable.

If I disable multi-GPU, my frame rate can drop as low as 55 FPS in certain areas of Biodome on an empty server. In these cases, I can definitely feel input latency. If I tap my mouse (in order to create a sudden jerky movement) and watch the screen out the corner of my eye, I can see the small delay. Even at the average 70 - 80 FPS, it still doesn't feel great.

This also had no perceptible impact on input latency. However, I was surprised to note that it prevented a strange frame rate anomaly that I described in my thread here:
