Game should be setup for 5.1/Cinema sound for best effect - the OS should switch to 5.1 output when you select 7.1 HP mode in the Connect software but you might want to double check that and also maybe fiddle in the Windows speaker settings with the speaker size (range) setting. The surround system used by the AE-5 is different to CMSS-3D with some pros and some cons - I can't quite pick out the distance to a sound source with the AE-5 as well as with my old XtremeMusic but I find the sounds movement more seamless and front/back representation better.
If you are using Windows 10 make sure the new Sonic Surround stuff is disabled as that will conflict with the surround setup the AE-5 uses.
Hmm, I've currently been testing last night with headphones direct-stereo/44.1kHz-16bit with everything else off for gaming. I'm surprised how very little difference there is between the Auzentech X-Fi Prelude/bit-matched and the AE-5. There are subtle differences but not much in the way people have made it out. Midrange is a little clearer which is creating a lovely crack of gunfire in CS:GO. Feels like the same lovely cracks of gunfire from Uncharted 4. It's subtle though.
The long piercing crack of subtle echo for the AWP is beautiful.
I saw default is set to 192kHz 24 bit on Windows 7.
The mid bass felt warmer on the Prelude versus the AE-5. I'm liking the more mellow sound of the bass on the AE-5 but it sounds a little bit more powerful in the very low end... The treble sounds very similar to the Prelude but nothing I could tell a great deal of difference.
The directional sound in stereo is clearer. The distant sounds is clearer to right up in behind the doors. Not that I didn't have a problem before but there are subtle clearer changes. I feel so dirty going back to 3.5mm for the AKG K702.
The biggest change is that the system performance feels so much quicker and smoother since there is no spikes above 1000 with Latency Mon, sometimes hitting 1400 with the Auzentech X-Fi (2011) drivers.
I wish I had the tools to record the frequencies of both cards.
I'm also greatly missing the headphone amp since it had the dial. Now using the sound controls on the keyboard. I'm also shocked how small the driver package has become... 68MB?
