Mouse rate vs game fps

I have a problem. When I set the maxfps to 180, 240 or 300, my mouse still lags sometimes. Mouse feels like it change sensitivity during that lags but the fps indicator shows still a max value. I have tested 2 different mouses.

For many games is 40 fps (or vsync on) enought for confortable playing. Then mouse rate is normal and moves feels not delayed. Why it is not same in Sauer? For Vsync ON I see that mouse moves are also delayed.

For Sauer fps = mouse rate?

Thanks for answer!

"Do you have the same problem if you play with an ordinary mouse?"
I havent ordinary mouse for the long time , if I will find some, I will test it. But I already tested 2 mices. Is there also problem at you? ...I mean: Does your mouse sampling rate respond to the fps in the game? I asked also players in my clan and they confirm it...

I don't have this myself (neither on Linux nor on Windows), using a crappy standard mouse with the respective OS's default drivers. I think I know that problem though, but in those cases it was always a problem with some specific game, and it usually affected all input, not just mouse.
Just to make sure I actually understood your problem: in those situations, when you move the mouse, it seemingly takes some time for the game to react, right?

If you twitch and shoot, the shots are more based on how you time them than how you aim. Over time you notice how a lower fps makes fast moves reduce your accuracy.

"hardware mouse" for some games comes up in my head... I'll google some.

nvm "hardware mouse pointer acceleration", it has nothing to do with this issue.

I have got a "similar" problem that solved using less polling rate.

instead of 1000hz putting 125hz

The mouse fell the same to me.

"problem that solved using less polling rate." But problem is not solved. You dont need gaming mouse then.

If you have a nvidia you can see if putting thread optimization off help to solve the mouse lag problem.

4000 Yesterday 04:12 am eihrul : mouse warping cleanups

you guys will sleep easy now knowing that the mouse problems have been rectified it the SVN. so hang in there.

I found this:
http://en.wikipedia.org/wiki/Screen_tearing

Wiki say: Input lag is with Vsync normal....

For limited FPS I see small screen tearing, you too?

So... what do you want?
1. Putting vsync on, which makes you having no screen tearing and looking damn great (and is automaticly capped to 60fps)?
2. Putting vsync off, which makes you have less to no lag in framerate (and having a capped framerate of 1000)?

"So... what do you want?"
I want no screen tearing for /maxfps 180 ...its all. Now I have to use maxfps 1000 so I see no mouse tearing and no input lag BUT my notebook is pretty noisy now.

Easy. Get 180Hz screen. You'll have no tearing and no input lag :P

As most current issues which have been discussed on here, just get used to it (or buy a 180Hz screen as Q009 stated).
I'm playing with 200fps, vsync off and I actually have no problems with experiencing screen tearing, no matter how fast I move my mouse.
I don't know why I don't get it though (but as long as I'm not getting it, I'm happy ^^).

issue should be fixed in the SVN, so all of you having the same mouse problems, wait for the new release.

no, i do not know of a date.

What I worked on in SVN has nothing to do with this, actually. So, no, it isn't fixed in SVN, and OTOH, I don't actually even understand the problem you people are complaining about.

There is nothing magical going on in the code.

Each frame goes like this:

1. Read any input since last frame and apply any changes in direction
2. Apply any physics for the time between now and last frame
3. Render frame (which shows all the updated positions)

What fundamental magical way are you proposing to restructure this, when, in principle, it is already taking your input, applying physics, and rendering the output, as quickly as it can?

Ok, will wait till next release then.

So that probably means Honzik is just having some hardware problems?

It likely means that he needs to tweak his mouse settings, either trough its software (if it even comes with such) or through his OS.
