Brilliant, thank you Dee-Jay! I-Hawks solution in the second link was exactly what I needed. This disparity was centered on Nvidias Vysnc option and forcing it to ‘off’ so BMS can handle it on its own and ther’d be no conflict between driver and software. I still don’t understand how external views wasn’t affected by this? The poly count can’t be that much higher?

To the others, there’s nothing wrong with my i7. The game runs fine with all settings to max. And yes, I did search for solutions, I know the rules. But the forum posts get so congealed with similar complaints it’s hard to sift them for solutions. All I could find were other people having similar issues. Maybe a sticky on the technical thread with direct links to posted solutions could resolve this for us newbies? 🙂
