Ensure stale perf history data, to ensure the data is useful and the perf graph widget displays useful information. - Remove stale data from the previous game when starting a new game. This avoids the graph showing values from the previous game when a new game starts. - Remove data that was collected during loading. This avoids displaying data points that were collected whilst the loading screen was visible. Data collected whilst loading is not relevant to the in-game performance graph. The performance graph when starting a new game will now display accurate information from the first tick of the game, whereas previously it displayed some stale information as well.
