KSP crawling after mouse software installation

[Wakaleo]

Just mentioning this in case others may have the same problem.

Yesterday the mouse manufacturer Logitech notified me there was updated software available (Set Point) so it was downloaded and installed. After rebooting, the computer was running very slowly and the mouse was doing crazy things (like scrolling three pages instead of three lines) and KSP was so slow it was unplayable, so the software was uninstalled. All is now good again.

I'm not sure what the issue is but since the mouse is working fine - and was before - it lends credence to the adage 'If it ain't broke, don't fix it!'

Was the update something to do with mouse polling frequency? I think there was a post a while back about mice with v high polling and refresh rates making KSP laggy.

never update anything

unless it's broken / you need the update to run something

I know it doesn't help you, but it's a guideline I've been using forever and it works for me.

there's probably a mouse polling (collecting cursor information) speed setting somewhere, google it. I had similar issues in some blizzard games with keyboard polling, though that was blizz's fault, they fixed it since.

+1 for using logitech, got a g5 murderweapon myself

Thanks for your responses katateochi and Borsek. As I mentioned in the OP, KSP is now running ok because I uninstalled the software. I simply posted the info in case any one else had the same problem.

katateochi - As I am playing on a laptop at 1366 x 768 a high polling rate mouse is not important for me. Perhaps one day I'll get a dedicated system that can handle lots of mods, parts and enhancements.

Borsek - I too have been living by the "don't update or install unless critical' credo'". Must have had a brain-snap the other day.  =D
