First of all, you need to run LoL with -cdtiming -legaia. There are no special settings you need to use beyond that. Basically use whatever GPU settings you normally use for games with heavy use of 3D, and many SPUs sound good with LoL (Eternal works fine).
it didn't work
when i typed both of them, the playstation logo appeared (which don't normally happen')
then i only type -legaia, or when i dun type any of them, then threre will be a black screen and nth will happen.
