offbeat

AA and vsync don't work in linux but I could give it a go (it's also why windows seems so smooth in comparison) I have tried ubuntu in the past and got the same issue - and you're right I really don't want to switch OS because I've only just got mint setup the way I like it and nothing is "broken" at the minute... I guess I'll just wait for an update or just use windows for ksp... thanks for your help, but the amount of time I've already spent on this has just been a waste

https://youtu.be/i0TxbTiqtFU There's a video - 2 things to note are I leave KSP running at the end and the stutters occur naturally as the memory is purged. This doesn't happen in Windows because the memory usage isn't really going up to 'force' the purge. Also using a wireless mouse with a lower dpi makes the memory usage go up slower (about half as fast), but still results in the forced purge

The thing I don't understand is why the reserved memory works differently in the Linux version of the client. Pressing a mouse button down and moving the mouse makes it shoot up until it becomes purged, whereas in windows it stays fairly constant and hence doesn't get purged every 5 seconds causing the stutter. I am fine with the normal stutters of the game but this one is making it unplayable for me... And it just doesn't make sense as to why this issue is occurring

I've got a problem in linux where a stutter is occuring every time the ksp memory is being purged - it happens in windows too but not whilst I've got the mouse buttons held down - in linux using the mouse makes the memory purge more often and turns into a big stutter every 4 - 5 seconds when the mouse buttons are being held down and the mouse is being moved. I have already tried turning the mouse polling down and messing around with drivers etc. but this clearly seems to be a linux ksp problem. If I don't do anything the 'Allocated' and 'unused reserved' memory in the debug menu goes up by 0.1mb every 3 seconds or so - until the 'unused reserve' hits 10mb and then the purge (and fps stutter) occurs. However if I press a button down on my mouse and move the mouse around then both the allocated and unused reserved shoot up whilst the mouse is in motion and increases by about 0.3mb every second - resulting in a stutter every 4-5 seconds or so (the same stutter would happen naturally, but every 40-50 seconds because the memory is not being purged). I am not sure if there's anything I can do to remedy this? edit: just to add that I've tried this in windows and the memory allocation doesn't increase whilst the mouse buttons are held down and the mouse is moving - something is wrong with the linux client in this regard
