Hey guys, do any of you know any ways of increasing the FPS? Does changing the brightness do anything, or clearing your Xbox cache? I already have it installed to my HDD.

You can't do nothing, maybe next patch will bring some improvements

Usually Particles effects and explosion slows the game, my suggestion, DONT LOOK AT those situations, to avoid framerate drops.

So I can keep eye out for targets instead of mesmerizing at awesome effects of CryEngine3 lol

Buy a PC lol

Best you can do for an XBOX thats out of warranty or already taken apart..
1 - Install to hard drive.
2 - Clean your heatsinks and remove dust.
3 - If you can, get better heatsinks and better thermal paste.
4 - Add fans to the xbox case or to the heatsinks..
5 - Keep the room the xbox is in at a cooler temperature, cooler xbox means better performance..

Yeah my Xbox is out of warranty. I don't want to open it up however so maybe I'll just buy an intercooler some time.
