From the ED Launcher (after starting the Oculus software). Really don't want to fart- around with Yet Another Weird Install Location now I have everything setup (I normally use several 3rd-party apps such as EDDI and EDDiscovery).
I do have a Steam key already, but really hate the fact that Steam downloads all versions of the game (32-bit, 64-bit, and Horizons) as well as needing to click through half-a-dozen Launchers/Windows to start it up (ok, slight exageration, but seriously, FDev & Valve need to fix this!).
Had a bit of a longer play today and while yes, the immersion is fantastic, the (lack of) resolution is seriously bugging me.. not sure if I'm going to keep it or wait for next-gen VR.
I don't think it's your usb. I had not been playing Ed for a few days and yesterday I was running a couple of test for about an hour. The focus switching happened to me twice in that time (once at launch), of course killing my hotas and mouse. My system hook up (or anything else) has not changed in months and was without issue before this. I ,as well, thought I had just clicked the mouse outside the window and dismissed the situation. There also seems to have been changes made to mouse behavior in the game by Frontier. I use the mouse for most functions in the GM. The mouse no longer drags the map when I hold down the left button, nor does the right button control my Z axis -it now rotates the camera. I have changed no in game controls in months, as well.The mouse cursor now hovers in 3d space. All this has changed in the last few days. My guess is Frontier may be trying to make the mouse work in VR or something like that and a bug may be causing the jump in focus. I will do some extended play testing tomorrow and update my findings.
As to your displeasure with the resolution, if your are coming from a 4k setup, VR resolution in ED will be a step down for sure, but you can improve that quite a bit by increasing the hmd setting to 1.25 or more depending on you rgpu and various other tweaks posted in this forum. As well, your brain adapts in short order and the immersion takes over. ED is not a native VR game and games like Robo Recall give a better representation of 1st gen graphics. Almost all 4k users state they still would rather have the VR. Next gen hmds are likely a couple of years out at least.
