Try enabling "Skip EFB Access from CPU" you won't be able to pickup starbits, and use the pointer in general, but it absolutely neuters performance at higher IRs. Its vastly more demanding on the cpu than enabling LLE. Only seems to be a problem in SMG games afaik.
In the hub of SMG1 I get:
HLE:
Enabled (skip EFB Acess): ~280% at 1x and 4x IR
Disabled (don't skip EFB): ~280% at 1x and ~170 at 4x IR
LLE:
Enabled (skip EFB Acess): ~225% at 1x and 4x IR
Disabled (don't skip EFB): ~205% at 1x and ~145 at 4x IR
Comp: 4670k at 4.4ghz with a gtx670
