The Spatial Sound Card just got a major upgrade to the internal algorithm :) Don't worry, the resulting audio quality will be 100% like before, but now there's the option of producing the exact same result with less CPU usage, if you accept a tidbit more latency. We're calling this new functionality "Latency Target". You'll find it in the options menu and there you can choose how much audio latency is tolerable for you.
For example, when you're watching a cinema movie ( = 30 fps ) on your laptop during a train ride, you probably want good battery life and you just don't need a 60 fps audio responsiveness, because it's a 30 fps movie anyway. Or on the other end, if you're an absolute shooter fanatic, you probably don't give a hug about CPU usage, but you want the lowest possible latency. Personally, we enjoy both movies on the train and shooters at home, which is why there's this new configuration popup for you too select what you want.
We also added Windows 10 and OS X Sierra compatibility, alongside with a re-worked minimize to tray functionality, just like you requested on the forums. New are also the value popups for the speaker levels, so that you can fine-tine your sound experience numerically.
And lastly, we've added a parameter tuning and tour video to our steam page, to give you a quick overview of the new SSC features, and a gameplay video with scenes from Counterstrike Go to see the Spatial Sound Card in action
