I'm playing on a 2010 Macbook Pro and I'm getting some pretty big FPS drops throughout the game. Reducing video settings to Very Low with no shadows improves the framerate but it's still a rollercoaster experience. I've tried different caps to no avail. On the Windows client on the same computer, I get 60 fps capped with all settings Very High except Medium shadows, and it stays pretty stable except maybe dropping to 50 in extreme cases. Both clients are at full resolution.
Does this happen every game or just that one time? If possible can you load the r3d log from that game located in:
/Applications/League of Legends PBE/Logs/Game Logs/
Can you check in Activity Monitor if anything on your computer is using large amounts of the CPU?
Can you also post the following system specs:
- System and exact System version, like this: Snow Leopard 10.6.8
- Mac Name and Generation, e.g.: MacBookPro6,2
- CPU, e.g.: Intel Core i5 2,4 Ghz
- GPU, e.g.: nVidia GeForce 330M GT 256MB
- RAM, e.g.: 4GB
