There are a couple of maps in AOM-DC where I've noticed pretty awful performance issues, it first happens in the car park map (first one after you escape from Markland hospital, forgot to screen grab that one, sorry), and then again in a couple of other maps. The actual frame rate stays at what should be playable levels (though it does also drop a bit), but something is causing the frame time to leap all over the chart. This happened both with my old card (R9 280X) and my current card (RX480). This doesn't happen in other mods, only AOM, so whatever it is, it's specific to AOM. If anyone has any insights that might help I'd appreciate it (I've already tried running with high process priority, and disabling tesselation, vsync, and anti aliasing).
