Jamesp1 Posted October 4, 2016 Posted October 4, 2016 Firstly, the Rift is fantastic in DCS. My four year-old has no interest in flight sims but begged for more chances to sit in the helicopter. I have a i5 2500k @ 4.6Ghz and a GTX 1080 which runs the sim with ease: With almost all settings to high and 2.0 supersampling I'm getting 45fps flying down by the casinos in the KA-50. MUCH better performance than I was expecting! Anyway, the sim seems to really like sticking to 45fps. I've seen it less and I've seen it at 60 - 90fps, but it really seems to love that 45fps. Even if I put all settings to low I still mostly get 45fps... I assume this is ATW at work and is normal?
louisv Posted October 5, 2016 Posted October 5, 2016 (edited) If you use the Steam version, that may be caused by SteamVr, which does this 45 fps downshift for the Vive. Sort of a cheapo ATW. It seems it will also do it for the Rift, unfortunately. It happens on Elite Dangerous but only in the Steam version, I'm just not sure that DCS is hooked to SteamVr the way Elite Dangerous is. ATW does not jump like that to fixed fps, it is adaptive and always on.

average_pilot Posted October 5, 2016 Posted October 5, 2016 If you use the Steam version...Stand alone DCS also supports the Vive.
mr_mojo97 Posted October 5, 2016 Posted October 5, 2016 Yeah, I'd noticed this a while ago. Sits mainly at 45 with mainly high and oculus settings at 2.0. I'm with i5 2500k 4.2 and a 1070. No idea why though. I have also noticed today that I'm getting a bit of judder, not sure if it's oculus driver related or nvidia driver related or the last update - first time I've seen it tonight.

Jamesp1 Posted October 6, 2016 Author Posted October 6, 2016 Nope, I'm on the standalone version too. I assume this is the same for everyone; is anyone NOT seeing this?

j0nx Posted October 7, 2016 Posted October 7, 2016 (edited) Even on my rig I mostly see 45fps with the occasional bump to 60-90 and sometimes less than 45. 30-45fps at 60% GPU utilization I might add. When I'm at 90fps the GPU is in the 90+% utilization range as well where it should be all the time. The sim just doesn't use hardware resources randomly for some reason. My GPU is always heavily used in non-VR mode when I fly in surround or 3D surround so the issue is solely with VR. I have made numerous posts about this issue but they always get lost in the static and nobody ever responds.

S-GERAT Posted October 7, 2016 Posted October 7, 2016 That's because DCS 1.5 is usually limited by CPU unless you are flying far for the cities.. or if there are some AI units around.. Nevada suffer the same problem when there are very AI units, but when flying alone you can get a 100 gpu usage over Las Vegas
