Just before, I lost yet another wait-a-day challenge (Sarven Treasure) because of many lag spikes before finally freezing until the time ran out.
The above screenshot shows where the simulation froze prior to running out of time.
As you can see, I was using the light-weight strategy of manually controlling movement using flags and I was close to reaching the goal.
What if there were options to change things such as graphics quality, remove the image in the background (map thingy in this screenshot, loading screen), remove the voices (when clicking on an enemy), etc.? Could that reduce lag?
An option to stop automatic simulation when the level is loaded would also be helpful.
