Is it possible that ReadyBoost actually slows Terragen down? I'm on a much older system, a Xeon X5450, with a old, and recovered HDD, so I thought I'd use a dedicated 32gb USB 3.0 for ReadyBoost to get better performance considering my HDD, it "seemed" to have worked when I was on my other PC, but I never used with without ReadyBoost, I just activated ReadyBoost, and renders which would take 3 minutes (the spires I shared) take 6-10 minutes. The only thing I can think of is ReadyBoost, or the stability of the system altogether (been getting strange errors).
Does anyone have any knowledge into ReadyBoost and Terragen? Maybe you do, Matt? It was popular back in the day.
Was also thinking of downgrading to XP for possibly better results, but not sure.
