FakeLight option worked in Crysis 1, Warhead and the freeSDK. Why not in Crysis 2?

I wanted to have many lights with coronas but without the FakeLight option the editor crashes often because of the very high dynamic light count. Too much for deferred lighting, it seems.
A Light Propagation Volume doesn't help either because it disables the coronas :|
Any workarounds? Or will I have to wait for Crysis 3 to be able to make mods using light coronas


EDIT: Actually, even while using Fake Lights in the Free SDK, the system chokes with 300 or so too, lol.
