Simple! Install the Temperature Gauge Killer The error log will tell you that the game was not allowed to write to memory. Whilst the game itself plays stable, after a while (depending on your play session lenght) you will inevatibly crash to desktop. Which will slowly but steadily increase the allocated ram while you play. There is a memory leak involving temperature gauges KSP stock comes in at +-3.0 gigabytes of ram KSP 32 Bit has a memory limit of+-3.8 gigabytes of ram Since that thread was indeed a troll/whine thread, the fix probably deserves its own thread, and possibly a temporary sticky till its fixed. So in another thread I posted a concrete sollution to the current memory leak with temperature gauges.
