Hi guys, yes I should have come here first. Yes It does appear to be Steam is the culprit. Still I live and learn. Hopefully others will gain by my loss. Thanks for the feedback. I can say since running this version the system runs a lot smoother, and I am running an I9-7900X with 32gig 3000 memory. and M.2 SSD, with 1080 video. So it normally goes like well brown stuff off a shovel. But I can see that they do not use the GFX card to it's full potential. the Cpu seems to work very hard.
But I digress you have indeed answered my question.
In relation to the purchase how do they police there corporate copyright on KSP if there is no DRM? Or should I not ask!
Thanks agin for the fast response. Regards Stephen. AKA. Lankspace.
