I tested version 1.1 on my R9 Nano 4GB (Win 7) with Adrenaline drivers and it does not work. No errors are reported, the command line simply goes to 'pause'. Are 15.12 drivers an absolute requirement?

And I wonder, would there be any additional performance increase from Vega Frontier Edition's 16GB RAM compared to Vega 64's 8GB? Maybe it would make sense to add support for it...
