Hey dude, good to hear from you again.
When I've been saying "single threaded" I mean it's just using the few threads it does (as you explained in your lengthy post before) and I have linked back to the thread so people can read it themselves. I've checked threads in use on HWID during games and I can see it's not strictly on 1 thread, somebody else posted something similar a couple days ago too.
I think when most people talk about "multithread" in this context, we're generally talking about using way more than it does right now, given that there's CPU's with 16 threads out there today. It just feels like a bummer knowing that this game was marketed as being well optimized (and it is for lower end PC's) but everybody else with more modern machines are found wanting.
My post was to clarify that on higher end systems the best way to improve framerate is to increase core-clock of the CPU and to let people know upgrading their GPU wasn't go...
