1. Yes, it's running in full screen. 2. Yes, it's on my laptop monitor. 3. Well, The Sims 4 also runs poorly, even GPU-Z's stress test in fullscreen. And the log says the clock always stays at 300MHz. But I'll try it just to be sure. It is MSI Z70 2BA-2291TH (http://notebookspec.com/notebook/6162-MSI-Z70-2BA-2291TH.html) And here is CPU-Z's full report (http://pastebin.com/S8sWK4Qj) How do you force redetection of GPU? I actually reset Windows from zero though. Also, the RadeonPro is all greyed out. Afterburner unadjustable too. Even after I've activated OverDrive via WHQL UnifL (double checked). So I guess it's BIOS-related then?
