I downloaded the 18.40 as that matched the year of my iMac. The interface is terrible, laggy, and even crashes. It's not even called Adrenalin - it's "Radeon Pro and AMD FirePro Settings." It's missing the target frame rate feature, AND it lacks 1600x900 resolution options for games & Windows. It was the perfect medium between resolution and performance at a proper 16:9 aspect ratio. For example, on the stock driver, Tomb Raider 2 ran at a decent 40fps at 1600x900 at high settings. I was hoping to bump up to maybe 50-60fps on a new driver, with the same settings/resolution/aspect ratio. Windows 10 is completely updated.
As for my request, I can't seem to find a BCD.com driver appropriate for my 2017 iMac, unless I'm reading things wrong. I have a model iMac MNE02LL/A. Radeon Pro 560. Looking in the Windows 10 folder on the mega.nz page, I see iMac Pro, iMac 2019, Vega 16 & 20, Older 17.x.x Versions, and legacy Macs (2013 and past). Does maybe the iMac 2019 folder denote the year of the driver and not necessarily the Mac itself?
If I'm looking the wrong way, what's the best route for optimizing my Mac for gaming? I realize it's not exactly a gaming machine - I just want to make the most out of what I already have.
