As soon as mouse is moved, framerate breaks down completely

Spaceforkz · March 2013

Hey guys!
So I bought NS2 a few weeks ago and really like the idea behind the game. BUT:
everything works fine, fluid gameplay, etc, but only as long as I don't move the mouse.
As soon as i move it, the game stutters, which makes it impossible to aim and kill

This, which irritates me most, also happens when i play on the lowest resolution (640 x 480). The menu has 100+ FPS, the game has 30 but as soon as i move the mouse, it starts jerking...
I tried all sorts of performance tips and took some screenshots from the "r_stats" menu:

not sure if this worked, if not, here's the link: http://imageshack.us/photo/my-images/248/2013031400002.jpg/

so this is on 640 x 480, all graphics off, without moving my mouse, just randomly running around.... 60 frames
as soon as i start moving my mouse (same settings), i go down to 4 fps...
in 1920 x 1080 and high graphics, the game also has a high framerate, as long as i dont move the mouse
sorry if this kind of post already exists, I didn't find anything in the search section, so maybe im just plain stupid

here are my specs:

AMD M4A79T Deluxe Motherboard
AMD Athlon(tm) II X4 640 Processor
8 GB RAM
Radeon HD 5670 (2gb vram)

I play Battlefield on High/Ultra fluently and didn't have problems with any other game. A friend of mine has a geforce gts 450 and plays on high, without any kind of lag.
My mouse is a MX518 from logitech, the prequel to the g400. Not sure if this information is relevant but I thought, I'd better add it

As you can see, it is impossible to play a shooter etc like this

Thanks in advance!

Do you have Texture-Streaming enabled?

Spaceforkz · March 2013

nope, all off

Go to main menu and try turning on and off Mouse acceleration and raw mouse input. If this doesnt help, try playing other games and see if same things happens, if yes - this is your system mouse settings.

Spaceforkz · March 2013

changed both settings a few times, just thought of trying out ns2 with a controller, will look into that tomorrow, the problem only exists in ns, any other game runs completely fluid in highest settings
thanks for the fast answers guyz, you are awesome

edit: no controller support, tried a dfferent mouse (logitech standard 10€ mouse) problem still persists

set the polling rate of your mouse to 125hz (not 500, not 1000).

Obraxis · March 2013

It would help if we could get a video of this in action. If you cant record with fraps, use a smartphone.

IronHorse · March 2013

I've used that mouse since day one of ns2 alpha, there's no driver or setting that should produce your symptom.

I'm thinking it's display driver related.
When you first open the game, at the menu check the console and ensure it says rendering device is your card.
Also are you familiar with how to use profile?

n0_FX · March 2013

its not the mouse, its the polling rate (driver), which can produce a large cpu spike -> short freeze when moving the mouse.

IronHorse · March 2013

I'd be surprised if the polling rate could drop 100 fps to 4..
But its of course worth trying

Higher polling rates strain the CPU. For most GPU-limited games that doesn't matter, but in a CPU-limited games I wouldn't be surprised if it caused in-game fps issues. It would manifest itself as fps drops when using the mouse. Revert it and the problem will (likely) go away.

Spaceforkz · March 2013

okay thanks for the answers, i will record a video with fraps right now and upload it to youtube.
how to i change my polling rate? I guess the MX518 goes with 1000hz but in the driver settings, there were no such options... (logitech setPoint)
i can only change acceleration, speed, smart move etc

not sure what you mean by profile so i guess, no

how do i check for the rendering device?

IronHorse · March 2013

In the past two weeks I finally made the switch from mx518 to the replacement g400.. glad I did! Notable difference in the mouse buttons.
But one thing I noticed Is that I was able to set my polling rate to 1000 in set point, something that I was previously unable to do with the mx518. (I played with registry tweaks with no real noticeable difference in the past)
Not sure if it was the latest set point software or the new mouse.

here's the vid

as you can see, impossible to aim

IronHorse · March 2013

Yes but did you try changing the polling rate yet??

Edit: yeesh you get poor performance even when not moving the mouse.. and your waiting on gpu never drops to 0.
To check the render device. Open the game, when sitting at the menu press ~ key, it will say render device and it should say your gpu

IronHorse, I love you (no homo).

You just fixed my problem I had in cossacks and it is the same as op's problem - whenever I move the mouse, the game was freezing. I set it to 125Hz and it's good!

IronHorse · March 2013

N0_fx posted that fix above in the thread. But sure I'll still take credit for it :-D

Ironsoul · March 2013

Actually the waiting on gpu is always 0. Does that indicate a cpu issue?

His cpu could possibly be overheating and throttling itself. I like to make sure about that.

IronHorse · March 2013

You're right i was looking at waiting for render thread, oops.

glad to help

Spaceforkz · March 2013

so what does that mean for me, now? as i said, all the other games work with high graphics without problems... and, how do i change the polling rate if the driver doesn't have the option to?
remember this is on the lowest resolution, so i really dont know why the performance is so low

Spaceforkz · March 2013

the link on that page doesn't work

i searched on other pages but many had me stay in "test mode" the whole time, i don't think thats how it should work...

Exoskelett · March 2013

The logitech mx518 just has a pollingrate of 125 wich is already added into windows as soon as it becomes installed - i know this because the mx518 is my old one. And i also know this framelaggs while moving the mouse - but anyways im not that low on fps like he is - for sure it dropps me some kind of 15-20 fps to turn the mouse also but around 100fps in the early theres nothing to complain, going worse about 60 fps and since build 240 its even much worse

n0_FX · March 2013

http://razerblueprints.net/index.php/View-document-details/18-DirectX-mouserate-checker.html try this tool to check your polling rate

stays on about 125 while not moving, when i start moving, it goes down, i guess it's based on how fast i move the mouse? thats how it seemed

don't forget, this is on the lowest resolution possible, its hard to read the map etc
Thanks for the answers so far, guyz, you are so awesome

125 atm, without moving, while moving it goes down quite a bit

That looks normal. Looks like your mouse polling rate isn't the issue. Would you mind recording another video with the profiler on (e.g. type profile into the console)?

Spaceforkz · March 2013

sure thing, recording right now
