Every time I start a resonance cascade the frame rate drops from 60 - 80 to 2 - 5. I don't know why. It doesn't lag on my Macbook Pro, but it lags like hell on my main PC. It might be my addons? But if it is I really don't want to disable them because it's a lot, and I use them a lot. I have 493 addons enabled. And I get decent FPS on the map regularly but it just lags when I start the resonance cascade. I can run other much bigger and more detailed maps perfectly fine. Like the World Trade Center map (gm_worldtradecenter2001) If anyone knows a fix please reply.
