I have an MSI X370 Gaming Pro Carbon motherboard and apparently they've decided to work just with Nahimic instead of Realtek's native software... why, I don't know. Realtek seemed just fine, maybe Nahimic offers better software. In any case, I wouldn't know yet!
I've downloaded it from the windows store, but the app doesn't open. It will say "Loading..." for a couple seconds then the app crashes. Nothing I've tried works. Any ideas?
