Probably my own fault but after some time away from playing I got back into it and did a new stick map in my CH Control Manager software. - I started to get regular sticking views recently, nearly always very noticeable when fighting! - and then quickly dying!
I had to think about this as I knew it was not a mechanical thing but a software issue. A quick look back in the stuck direction would unstick the view. In other words the game did not always pick up the key released signal from the Control Manager (I am still using V4.20).
Looking into it there is a value for repeat rates but not what you might think as character repeats per second, but 1000ths of a second between repeats. In other words a higher value is a slower repeat rate. I virtually doubled the value to slow the repeat rate and for the present the problem has gone - now using 100.
I would be interested to hear if other CH users have had similar issues and found the best solution for them. I also wonder if a higher performance PC may be less prone as it processes the game software with greater ease? - So if you have a problem, is your PC fairly old and basic? Mine has a AMDx2 6000+ processor (that's 2 cores running at 3000MHz) and 4Gigs of Ram with Windows XP - I still use FS Autostart to shut down resources and launch the game and get 60fps normally.
