Yeah but how can I force a half refresh v-sync?
For Nvidia cards I use inspector, is there an equivalent for Amd?
Edit: Eh.. i was looking exacly at an Asus Strix r9 390x... xD why are you not satisfied?
As far as I can tell, Asus didn't do anything with the 390/X Strix cooler, just re-used the one from the previous generation. It's not at all suitable and prone to overheating. I would suggest MSI or Sapphire if you're looking at a 390 or 390X.
