UE4.9.1 does not recognise Rift with 0.6.0.1, and has game breaking performance with 0.7.0.0

Hey Mechanicalsnowman,

Thanks for testing this and getting back to me with the results. Let me clarify a few things as it looks like I did in fact give you some incorrect information.

Does this mean that the direct driver mode is not actually necessary? My technical knowledge of this kind of thing is admittedly lacking, I assumed that the two (runtime and nVidia driver) needed to go hand-in-hand.

I have no idea about direct driver mode but I can look into this and see what more info I can get about this.

One thing though, your driver is not the one recommended by Oculus for the runtime 0.7:

I tried the 355.83 drivers and I could not get my HMD to attach to UE4 in VR. I was able to get everything working using the 350.12 drivers so I just rolled back. I have not tried the latest ones again because I was in the middle of working on something so I just needed things to work and that is why I used the older version because I knew that one worked. When I get some more time to dig deeper into this I will have a look and see if I can figure out what is going on.

r.ScreenPercentage does not change anything in stereo, the command there is HMD SP, right? Should I be using that instead?

This is correct however what r.ScreenPercentage does is tell you the current screen percentage and that is what I wanted to know. However now that I am re-reading my post I was completely wrong in saying use r.ScreenPercentage to set your Screen Percentage and you should in fact be using HMD SP (Number you want to use) command. Sorry about that it completely did not register that I was using the wrong command when I was writing the response as I was thinking HMD SP in my head but was actually writing r.ScreenPercentage. Also adjusting the HMD SP should be the last thing that you do when trying to get your game to run at desired frame rate.

Thanks again for testing this out and positing such detailed results. If I figure anything else out I will make sure to let you know and if you figure anything else out please respond back to this thread so that I can track it.

Cheers-

Sam Deiter
