Anyone else find it a bit naff that looking at the Foundry mission list has a massive impact on framerate? Clearly the game's doing something which has a performance impact that scales with the number of missions displayed, as the framerate impact disappears when only a handful of missions are returned in a search.
I've heard that their UI is CPU driven instead of GPU driven. This happens any time there is a large number of items that the UI has to render. It's most noticeable in the foundry mission list, and in your duty officer roster if you have 200-400 doffs, but it can happen with a large inventory or bank window open as well if you've purchased some size increases for extra slots.
