[Linux] High mouse sensitivity.

[vabi]

I use Logitech MX518 on raw input, the same settings on windows. i have even lowered the mouse sensitivity in-game to 1, it's still too high.

[Vash63]

I play with extremely low sensitivity even in Windows. Try using the 'sensitivity' command in console, I use 0.4 personally but I have a high DPI mouse. You could also try lowering the DPI on your mouse.

[vabi]

Oh, i didn't know that I can set sensitivity below 1. Thank You really much!

[Vash63]

No problem. I use 0.7 on Windows and 0.4 on Linux... definitely seems different. Not sure that's really a bug though, probably just differences in the core OS. I do wish they would allow lower sensitivity in the GUI considering no one plays competitively with higher sensitivity...

[vabi]

Yup, so it's not bug, I wasn't just aware of that you can set it below 1. Thank You again :+1:

Note for other players: If you don't/can't use raw input, you might get acceleration from your desktop environment. There's various ways to disable linux DE acceleration on the internet, though.

Try changing the CS:GO launch options to 'vblank_mode=0 %command%' and then see if sensitivity feels right. I had an fps cap of 60 that was messing with raw mouse input.

Early reports are suggesting the mouse sensitivity in linux is double that of windows. This confirms what I felt yesterday when running it with my old windows sens, (same DPI and polling rate as in windows). I need to do more testing for sure before I can say its definitively exactly double on linux though.

Razor death adder 2013 polling rate and dpi adjusted with - http://bues.ch/cms/hacking/razercfg.html

It not only feels more sensitive, but also a bit more "slippery". Even at low sens I find it really hard to line up a shot without it twitching away off target.

I think this is not CS:GO related, but the typical mouse settings most Linux systems have.

[markubiak]

The slippery mouse was my problem as well, folded solved by disabling vsync. Check if you have it on using net_graph 1 in the console

@Vabi, since you've solved this issue, please close it.

[wareya]

Ahh, the good ol "Mouse acceleration is framerate dependent" :)

[KaldNL]

@markubiak , it isn't vsync at all. This is also present in other games. It's not slippery as in delayed, but slippery as in too "touchy". I find it much harder compared to Windows to keep the crosshair on something while moving, and I've been using Linux for years. Only Windows gaming I did was with CSGO, which is when I noticed it's weird on Linux.

Hopefully there's some input setting I haven't yet discovered, or hopefully something that can be solved.

You're probably right, but disabling vsync helped me a lot On Tue, Sep 23, 2014 at 8:04 PM, KaldNL notifications@github.com wrote:@markubiak , it isn't vsync at all.

Are you sure this issue is resolved? I can confirm due to tests that mouse sensivity in Linux is twice as high as in Windows. However, using "raw input" on both, shouldn't mouse sensivity be identical?

[wareya]

It depends on the mouse/drivers.

[vabi]

Oh, it's not, but i closed it due to theGeek "closetheissue" Pirate. reopen. I suppose it should be identical.

[seaweeduk]

Can confirm sensitivity is exactly double for me on my death adder same dpi and polling rate as windows

[wareya]

Which model of the deathadder are you using? If you're using the 2013 version, settings are stored in-driver instead of in-hardware.

[hadiskeini]

The issue is not related to settings being stored in the driver. For instance I'm using the G502 with settings stored in-hardware, therefore same dpi. Also the pointer speed is perfectly normal in the OS itself.

[seaweeduk]

i'm using the 2013 version but i have http://bues.ch/cms/hacking/razercfg.html to manage my driver settings

people on reddit with various mice also said halving the sensitivity was consistent for them too...

[yoyosan]

Try disabling acceleration like this: https://wiki.archlinux.org/index.php/Mouse_acceleration#Disabling_mouse_acceleration

You still need to have half the sensitivity on Windows, but at least for me, the mouse is more precise.

[hadiskeini]

Acceleration is already disabled and even if it wasn't already, it shouldn't have any influence in-game.

[thatarchguy]

This is still a problem. Sensitivity is double what is for Windows. raw input = 1 I run 2.5 on Windows. 1.25 on Linux is a match going by adreN's guide "checking sensitivity" video

I think this is a bug in older versions of SDL2. The changelog for the 2.0.4 release states the following under the Linux category:

* Fixed duplicate mouse events when using relative mouse motion

I tried out my system version of SDL2 which is now sitting at 2.0.4 and things seemed pretty fine.

@davidw-valve this was fixed in recent update, please close.
