Starts off smooth
I can get mine to run in Direct mode (on 0.4.3) but I get a strange double image which looks like time-warp over compensating for movement. Extended mode looks and runs better but but head tracking seems laggy (on the outset.
So I uninstalled 0.4.3 <rebooted> and then re-installed 0.4.2.
Extended mode is now fantastic, sitting in the station it's silky, perfect tracking, 75Hz low persistence, the whole shebang and 3.02 is looking gorgeous. So happy. So I fly out, all looking great, jump, still good, SC to an space station, leave SC, still great, request to dock and pretty much as soon as I'm inside the space station things go awry, out of nowhere FPS dives to I'd say 0.5 fps and stays like that, docking becomes a nightmare, no matter what frame rate is obliterated even in the quit game menu :S
I've done this a few times and it's the same each time irrespective of the type of space station (although I haven't tried a titchy outpost). There clearly a bug somewhere, 2.06 was massively better performance-wise on my rig.
Spec's: i7 4790K @ 4.4Ghz, 16GB DDR3 @ 2133, Gigabyte Z97X-SLI Mb, Nvidia GTX 980 (reference design @ stock speed), main display @ 1280x1024 @75Hz, i7 cores un-parked, OVRServer_x64.exe elevated to high priority, Windows 7 SP1 Pro (fully patched to date). X52 Pro.
screen connected via Display Port, Rift connected via HMDI (and USB 2 for both the rift and it's camera), OS & ED installed on a 256GB Samsung 850 Pro.
I'm sad cos I need my elite fix, hell ED was the main reason I brought a DK2 (and then my PC...)
Gonna give it another go on Solo mode to see if it's some bizarre network issue. I'll report back.
