Hello forums, after getting my Vive yesterday (previously I was using a DK2) I jumped into DCS. Performance is worse, a lot worse than the DK2. I haven't measured FPS as yet so this is subjective, but it would appear that the oculus timewarp was doing wonders for playability. With the vive there is severe juddering when looking around, something that I suspect timewarp was smoothing out exceedingly well. For instance, when using fraps on the DK2 the red number (shown while recirding) was in the 30s and I could still look around without being distracted by judder. I'm using a gtx980. Edit: I believe the valve version of this is Reprojection, but so far the implementation hasn't provided the results one could expect.
Mostly the frame rate suffers when looking at buildings or regions of the air/ground where there are a lot of units, so this is an issue on dense multiplayer maps like Open Conflict. I've compensated by putting almost everything on low detail/quality settings. On the DK2 I could even have shadows on high and be OK, even with cockpit mirror reflections on.
The other odd one is that I've bound numpad 5 (recenter VR view) to my saitek x52pro, and it's misbehaving quite a bit, possibly a saitek thing though. If I press it once it will recenter, and then lock the cockpit to my head's yaw. If I press it again it will release and leave it there. Either way, what's nasty is that there is a LOT of judder when doing this, kind of like when you first start in the hangar and look left and right to load things into memory. Quite untenable if flying close to the ground.
I imagine a lot of this will be resolved as development progresses, but thought this info would be valuable to the devs and anyone else wanting to try this out. One day I hope to have a better experience than the DK2! Although in retrospect, the DK2 experience was quite good as the resolution bump hasn't provided *that* much more clarity. It's still bloody difficult to see things/text/hud. Oh, and the map doesn't display it's texture. That's pretty annoying hah.
