We are updating the Test Server with a variety of small changes to address stability and memory leaks. There isn't a specific list of all the changes, but please pay attention to any changes in behavior for:

  • Frame Rate - If you notice a repeatable or consistent improvement or loss of frame rate, please report it.
  • Memory Leaks - If you see or notice any change in memory or frame rate over time, we are interested.
  • "Spontaneous" crashes - Several of the changes would appear to be random crashes, but could be crashes related to in-game special effects, logging in or out, and other strange (but not generally repeatable) crashes.
