A dedicated Resolume environment via a Multiboot can be a good thing.
Have done it before, but have been some time ago before the Multi-core era.
In conjunction with a dedicated boot I also stripped my Windows OS of all unnecessary processes and services.
All of my resources (RAM and CPU) was available for Resolume.
Well the times have changed and technology evolve with better processing, so nowadays I take those things for granted. Computers are fast and cheap , now instead of multi-boot I just get another box with super GPU powers. New computer with new Resolume is good.
-Well easy way, Install another harddrive then install OS.
-Maybe harder way, partition harddrive, then install OS.
-Costly way, bring it to a computer shop ask them to strip it.
If you cant do any of the above, then I think "You are in over your head".
