Please clarify something.

I just recently upgraded my OS from Windows 7 to 10 and noticed a performance drop.
I run Elite through Steam but I have never installed Steam VR having been scared to go anywhere near it or room scale either in Oculus or Steam, as I only bought the Rift for Elite/Project cars and DCS and may have wrongly thought that room scale would be a lot of unnecessary hastle when I am only sitting down to play a game. (controllers sitting in a draw collecting dust)
If steam VR is not installed (and it says its not on my Steam download list) then when I right click Elite in my Steam library why does it say play Elite in steam VR and then it runs?
I like to set my own SS settings and in Windows 7 that was set to SS 1.5 and it all run on high/ultra just fine but in Windows 10 I have had to put SS all they back down to 1! and HMD still at 1.75 to get very smooth gameplay on high/ultra.
Is the new Steam SS settings overriding something even without Steam VR installed?

I only changed my OS as my system is ok with a 8700k @4.8 and I run Titan xp (£200+900 favour) .
I am so confused with all that runs in the background in VR I may never find out what the performance hit was.
Maybe Nvidia?

Clean install?

Yes everything formatted.
And a new SSD slightly faster than my old SSD.

Is the Steam VR install just the room scale bit or is it the total package?
If so is Oculus running the game even though my option in Steam is to only run it in Steam VR?

I don't run Elite through Steam, but as a standalone. If I'm on the Rift, it all works fine.

If I decide to play in 2D, I'll stop the OVR Service (Oculus' listening service), and start up Elite with my Desktop settings loaded (Using Dr Kaii's excellent EDProfiler). At this point, just as the game intro screen loads, Steam VR pops up because it failed to find the VR service. I then need to manually quit Steam VR, and then go back to Elite. Then it all runs smoothly.

I guess why I'm telling you this is because it is layers upon layers! You can't run a Steam VR game if you close down the Oculus app. Who knows if Steam VR sits there all the time running away (with your VRAM...) in the background when you're just running an Oculus app or just on email and web-surfing

I used to know how to cull all services and squeeze every last drop of juice from my PCs. But as they've become more complex, I've become more clueless!

Win10 has this Game Bar feature auto-enabled that can mess with your VR performance. Let me look for a thread....

Yep, here it is.

Post back & let us know how it all goes.

Hi thanks for reply,
I checked windows game mode and using the game bar I was able to confirm it was already off by default so it was not that causing a performance drop compared to windows 7.
Maybe Nvidia drivers just worked better with windows 7 at present!
Still not sure about this steam SS control thing but I think they introduced that a week or 2 before I changed my OS to windows 10 and I never saw any change while still in 7.
Maybe the next set of Nvidia drivers may show a improvement. I have already rolled back to a more stable driver but still not running at the level I was on windows 7.

Got the Steam version myself, but run the game directly from Oculus Dash, and no mess with Steam VR or anything there. You can get the required Oculus code for free from the FD site. Possibly, that helps, but it's another 16g download.

Elite has native Oculus support, you do not want Steam VR turning on when you run it though a Oculus.

Normal Oculus rendering is:

Game renders super sampled > applies barrel distortion to bring higher res down to fish eye shape > renders to head set


With Steam VR running with Oculus on Elite it does:

Game renders super sampled > applies barrel distortion to bring higher res down to fish eye shape > Steam VR intercepts, undoes barrel distortion > adds Steam VR interface > applies Steam VR barrel distortion > renders to head set


Taking any image, shrink it down, make it bigger, then shrink it down again, it will become a pixilated mess, also having another program force to have to intercept, which is slow, inject, which is slow, and then undo and redo the distortion phase, and then remember it is doing this for both eyes, means more processing time, looks worse and gives less fps.

80% of people that come to my stream complaining that they cannot read text is because they are running Steam VR with an Oculus, 18% is because they are using a Vive and did not turn off Steam VR Theater ( causes the expanding and contracting of just the text layer causing it to go blurry for Vive users ) the last few percent is was people messing with supersampling incorrectly


General rule is, if any game has native Oculus support, you do not want Steam VR involved unless you like to reduce your performance by forcing it to do everything twice.
