PresentMon is interesting, but for my needs, not certain it is the best choice. I am so used to afterburner. It is neat how the fps numbers differ from each other. I'll take a screenshot if you want Igor. Not certain how I should configure it from the defaults either.
The new drivers didn't do anything significant for AC: Origins or Watch Dogs 2 in DX11. Switching to Vulcan in Origins doubles the fps from the 40s to the high 80s low 90s.
In WD2 the A750 is still being poorly utilized at 1080. Often only in the 60s and 70s percentage usage. Meanwhile fps can dip to as low as the 30s. I am starting to think the HD texture pack is the problem. While the used vram says it's under 8GB the allocated goes over 8GB. That is one of those bugs with AB and ARC. Reporting use of more vram than the cards have. I have a blend of mid and high settings, even trying FXAA and low shadows to get the frames up. But as soon as I get outside with a fair amount of draw distance, the fps tanks.
