If you are having problems with your Alt / Space keys for viewport camera controls; check your Volatile Keys, Ensure that Volatile View is bound (Bound to Space key by default). Seems obvious, but it took a while to find this setting / realise it was related.

I might be having a similar issue. Just used the performance monitor, much of the time is marked unaccounted. What is unaccounted?
