 +===== Common issues =====
 +
 +==== Doomsday started crashing and even reinstall won't help ====
 +
 +The problem may be with the persistently stored configuration settings. Try clearing the [[runtime folder]] or just deleting the [[persist.pack]] file.
 +
 +==== Low FPS / renderer slowdown ====
 +
 +Since version [[version:​1.10]],​ the renderer has been inflicted with some performance bottlenecks.
 +
 +Here are some things you can do to see what is triggering the slowdown:
 +  * If reducing pixel density or window resolution/​size increases FPS back to 60, the problem is that the GPU is too slow. It might help to disable the Bloom effect in this case.
 +  * When in a large map you notice the slowdown (perhaps looking at a large open area), does the FPS significantly increase if you turn and face a wall so that nothing but the wall is visible? This would indicate the slowdown is caused by the renderer'​s per-frame geometry processing.
 +  * Does the slowdown go away if you don't use add-ons? Some maps have tons of objects or light decorations so rendering these might get expensive. Some texture packs may also be too large to comfortably fit in GPU memory. (4 GB GPU memory should be quite OK, though.)
