Some maps drop FPS significantly, sometimes even lower than 60.
I’ve tried lowering graphical settings, but that doesn’t seem to do a thing.
I have Sapphire R9 270X TOXIC and AMD FX-6300 Black Edition. I don’t think such issues should exist, but they do.
The best example of that would be the map ttt_waterworld.
Vanilla maps run at over 200 FPS.
Other maps run from 70 minimum to 150 FPS on average.
Though, I’ve noticed that when pools close on ttt_waterworld (water and its reflection cannot be seen) the FPS jumps up by 15 to 25 even.
I find this really odd.
