Acceleration and Hertz Issues

1. Modern USB mice don't work properly in Cross Fire.

First thing is shaky, wobbly, erratic mouse movements in Cross Fire.

I’ll start off with this video; http://www.youtube.com/watch?v=wmgGyNwhTqc

I don’t have much production quality to work with, but watching closely you will notice the difference between the first few games and Cross Fire. In Cross Fire it doesn’t matter if you move from side to side, or up and down, your movement is going to bob in a direction that isn’t straight.

In my case this happens because my USB polling rate is “too high”. (Based on THIS) 500hz, the default for Windows 7, is apparently a little too much for Cross Fire. To fix this problem you need to invest in a mouse that has software with customizable polling rates, or patch some files to lower the rates. (Example HERE)

Edit: Some mice have lower rates by default, you may not notice this issue.

Why should we have to do this? A lot of you have modern mice and use Windows 7, and because Cross Fire can’t handle modern software and equipment YOU have to work that much harder just to aim. I personally won’t be tweaking my polling rates because I messed up USB ports pretty bad once. I’m sure it’s easier now, but I think your still taking a chance.

TL;DR : Cross Fire can’t handle standard USB polling rates, makes you waste effort on aim.



2. Negative mouse acceleration provides no consistency.

The second thing, again, is about mouse acceleration. (Continuing from HERE)

There aren’t that many top players around the world that use mouse acceleration, most try to keep mouse movement at a steady consistent pace. This makes sense considering your mouse is pretty much your top priority in gaming. Random isn’t for competition, competition needs consistency that you can practice and rely on. What we have here in Cross Fire is RANDOM. Here are a few videos if you want to watch;

- This shows how negative acceleration is not consistent.
- Negative Mouse Acceleration Demo

- This shows, again, how negative acceleration kills precise movement. (LOWER YOUR VOLUME)
- Razer Deathadder Negative Acceleration Test (450dpi)

- Just a simple guide to check for mouse acceleration yourself.
- [HOW TO] Check if mouse acceleration is enabled or disabled in your game

A lot of people really hate mouse acceleration, especially in the Quake community. Players who go competitve want everything to be extremely precise and consistent. It's the reason people have done research and testing about MOUSES USING FLAWLESS SENSORS and others create acceleration fixes like the famous MARKC WINDOWS 7 MOUSE ACCELERATION FIX or Rinput. No acceleration fixes truly work for Cross Fire, the problem is in the game itself.

TL;DR Cross Fire has mouse acceleration built-in, and it needs to get fixed. There is no consistency at all, and players in general have to work harder just to get good aim. Added to the acceleration you also have the hertz problem, doubling the effort you waste on aiming.



I just hope this gets to the right people, and I hope some of you get why it's an important thing to fix. I wasn't able to find too many good videos, and I'm sorry I can't make enough of my own, but I hope you guys get the point I'm trying to make. In any case I'm not expecting much here, I just posted this for someone and it will probably go away in a day or two. Thanks for reading, etc.
