Converted my machine entirely to Windows 10. Play a few games; Warhammer Total War, The Division, Stellaris, DOOM. All play on a 27" ACD at 2560x1440 very high settings at over 60fps.
Was previously playing The Division on a GTX 680 Mac Edition at 1080p and getting around 40-45fps, moderate settings.
Based on some benchmarking, I think the PCIe 1.1 16x bottleneck, along with any potential issues running a GTX 1080 FE on a Westmere chip and 1066Mhz memory only reduces the 1080's performance by 10-15%; less than if it were connected externally via thunderbolt (I think).
Alien Isolation, (still). F1 2013 and 2015, (not too much). Splinter Cell Blacklist and Tomb Raider.
I boot natively into Windows as the controller support on Macs is a crapshoot, (regardless of what the devs say). Can't remember FPS at the mo.
Also it seems some features don't work properly or I can't find the right info, one of the two. Has anybody actually managed to put anything in this field...........??? Have that on more than one title.
Had a GTX 1060 in my system, I play a lot of driving simulators such as rFactor 2, F1 2016 and Assetto Corsa. From time to time I also dabble with First Person Shooters such as Overwatch and PUBG.
I recently sold my GTX 1060, due to graphical glitches from the Mac driver, and dropped my HD 7950 back in. I've got a RX 580 8GB on order but for now I'm roughing it. Plenty of screen tearing going on and PUBG is unplayable.
Looking forward to my shiny new card. Should arrive in a few weeks time and then from September 22nd I'll be playing Project Cars 2 on it!
