I must confirm that ELITE Dangerous + Horizons in DK2 is something that everyone should try. For my part: it is the best game of all time, period because of DK2. DK2 and ELITE Dangerous is a massive virtual reality experience. You are not playing a game, in fact you are THERE. I was also worried a bit about the performance and FPS impact, especially with regards the mininum recommended hardware spec. Fact is that Nvidia GTX 980 is actually overclocked GTX 970, so nothing special, it´s in fact still the same card with regards the actual performance boost...
My spec as follows:
CPU: INTEL CORE i7 970@2.93 GHz 3.06 GHz
RAM: 16 GB
VRAM: ZOTAC GEFORCE GTX 970
OS: WINDOWS 7 - HOME / 64-BIT
OCULUS SDK: 0.5.0.1
PRIMARY CONTROLLER: HOTAS TTHRUSTMASTER WARTHOG
SECONDARY CONTROLLER: XBOX 360 GAMEPAD (SRV)
Nvidia chipset setting (in Windows): DEFAULT
in Game graphics setting: PRESET ULTRA
Custom optimization SHADOWS OFF, AMBIENT O. OFF, AA OFF, SUPERSAMPLING: 1.0
According to my hardware and listed optimization, the experience is silky smooth, no single issue and no matter where and when. Even the ride in SRV is totally smooth on any kind of surface I tried yesterday. I´m sure that when I will play a bit more with the windows nvidia custom profile, I can boost some performance or picture quality, but now... I prefer to play a game instead of fiddling with graphics

. I also confirm, that I´m running default DK2 drivers (0.5), no external mods needed. The AA setting is not so important in DK2. I learned that when I turn the AA off, the picture is much sharper in DK2, hence the AA - ON makes this game in DK2 a bit fuzzy - especially small assets and fonts. But it depends on personal point of view. As soon as the HTC VIVE and OCULUS CV1 will be out on the market I will start build my new computer. But Now? It is not neccessary at all. SEASON 1 HORIZONS is simply the best now!
