Description (last modified by Yves)

When starting a game with these parameters, then zooming out and moving the camera to the center of the map, the FPS drop from >60 to <20 on my Radeon R9 270(x). 

./pyrogenesis -autostart="random/deep_forest" -autostart-players=4 -autostart-size=256 -autostart-ai=1:petra -autostart-ai=2:petra -autostart-ai=3:petra -autostart-ai=4:petra

The same problem was confirmed on IRC with a R9 280x. The problem is the same on Linux with the open source drivers and on Windows with the proprietary drivers.

Philip reported 50-60 FPS in this worst case and even around 175 with the default camera perspective with a GF 560Ti. The performance with the other two AMD/ATI cards should be better actually.
