Question / Help OBS Setup for League/PUBG/SFV any game really

[Kenede]

Can't seem to fine tune the settings well enough to not have it drop my fps about 50 in league making it choppy anybody got any recommendations?

PC Specs:
I7 4790k
16G Ram
Windows 10 64Bit
GTX 1070 8 Gigs

Also does having alot of scenes make it lag in anyway?
Thanks in advance
