Recently it came to my attention that performance had degraded more significantly than it probably should have based on the recent updates to the game. Whilst attempting to confirm this, we noticed that the framerate would predictably dip significantly for no apparent reason, then recover. The higher your base framerate was, the more severe these dips would appear to be.
After doing a bunch of profiling, I noticed that there were some significant stalls on the render thread and our tree impostor system was most likely the cause of the issue, even though the population had only been tweaked very slightly recently.
With the fix, framerates should be a lot more consistent again (as long as what's being rendered is consistent) and should overall be slightly higher in general, particularly in areas with a lot of bushes and trees like Bandit Camp.
