so long as you installed the latest version you should leave them all as they are. they are now set at best quality and latency for a modern machine like yours.
one thing you could play with is dspbuffer in mast (change and press save). you may need it higher for reverbs, but could have it lower for eq/preamp. watch the cpu use meter. it will effect the latency the plugin runs, less latency = more cpu, but you can find the 'sweet spot' that is best for your machine
i have made two copies of the plugin with different latencies for this purpose.
