rpcs3 optimization on laptop

Don't expect to get any better FPS. There's really nothing you can do to get better perfomance, except getting better hardware.
If you want to see good perfomance come back in ~3+ years.

I run on a octacore I7 mobile with 860M and can run games really well even with no optimisation through RPCS3, only downside is that it appears most are broken, haha..

All mobile i7s only go up to 4 cores I think? Only like the i7-5960X and similar extreme edition CPUs have 8 cores (and 16 threads).
Most recent and good laptops can run RPCS3 just fine I believe. If you have some kind of i7 HQ cpu you should be good.
There are only 7 games in the playable list so yeah, pretty much every game is broken at this state. If you can't get one of those games to behave properly in the latest releases, you should report it (with a log).
