Launching map from editor has high res textures but drops quality on map change

I am launching my maps from the editor using the standalone game option.
When the level loads it has really lovely quality textures.

if i think bring down the console and type “travel map” where map is the map I already have loaded, I can see the quality of the textures are now lower.

I’ve been looking through the engine to see what could be doing this but I haven’t had any luck. Anyone have any ideas on what the problem may be?

If not, where can I look through the C++ code to check texture quality levels?
