Hey there community. I have been having an odd issue while playing KSP since I got it and never had this issue before I had KSP installed. Don't know whether it is mod related or not, or if it is an Unity4.x limit, as I have not found any info about my issue here on the forums. So that's why I post here. The problem. After KSP runs for more than 30 minutes, I start noticing that my system has instances in which it becomes less responsive, these instances show very high disk activity. Having a dual screen setup and I run a browser on my second monitor which also started to lag significantly when these instances happened. Ran Task Manager (standard practice) to see what is going on I/O wise after some ingame time. Results were processes: KSP.exe and CSRSS.exe, had I/O Writes and Reads counts that went through the 1 to 3+ million mark. Every time high disk activity occurred, were after scene changes and or when 'alt-tab' to look something up/mod some cfg's. My system: W7 x64 Intel X5460 @3.8 6Gb ram 6Gb swap partition on a different drive from OS + game partitions. Ram with KSP + FF + system still has 1.5Gb free, but swap seems to have increased to it's max size. Has anyone ever ran into something similar, or can anyone perhaps corroborate this?? Thanks Edit: I am just about to end another session, ksp is at 3.3Gb, now ~1.5 hours in and KSP.exe I/O Writes count stand at 14.97M counts and CSRSS.exe at 2.16M counts. FF is slow and somewhat unresponsive in browsing.
