Not a game dev. Besides profiling, I would create game scenarios that exercise certain parts of the game engine.
For example, I would create a game fight scenario where the player has infinite health and the enemy just attacks super fast at some settable rate. That way you could monitor whats happening in extreme abnormal conditions with the hypothesis that if the game works in extreme conditions then it will work in normal conditions.
Another example. If you have random encounters like in old school JRPGs then I would create a scenario where a fight happens per step of the player, the fight loads, then the enemy immediately dies, rinse wash and repeat. That should allow you to asses how the game performs after 100s of fights quickly.
The idea here is to create tests that improve your signal to noise ratio. So you create a scenario that will create a large signal so that then you can more easily diagnose the performance issues.
