Hi Ale, I don't know what might be wrong, but specs of your computer should be higher enough to tackle these scenes without problems. I don't use Windows so don't have any specific expertise on the platform. The only things I can suggest right now is have a look to see whether OpenGL hardware drivers are being used as you are getting such performance I wouldn't rule out the MS software driving being selected for some reason.
