How ED Should Run

Hi All

Love ED on the rift but I have kind of got used to having to compromise on graphics and live with stutter despite having a 980ti.

Just loaded flyinside for FSX, developed by an individual not a huge team for a program that has worse frame rates than ED on a monitor.

It uses low persistence mode and even though the sim is running at 40-50fps it is totally smooth.

Does ED use low persistence mode at all? If not why not? If one guy can develop this as an add on for flight sim surely it would be possible. Check it out if you have FSX or P3D it really is impressive.

@ Ryder35, have you gotten the the SDK 0.5 version of flyinside working? I tried it and i just get an error and the game will not launch. He keeps saying to update to the 0.7 SDK, but then I cannot use Elite and that is a no-go

I think what you are referring to is the Asynchronous Timewarp which will interpolate and motion predict the next frame if it isn't produced in time by the GPU. A somewhat related technique is used in some TV-sets having a "smooth motion" setting. It has as many names as there are manufacturers that use it. In televisions/projectors it is not always very appriciated since it can make 24p films look like 60i video (aka the soap opera effect) but it will enhance 3D-TV content and make it less motion-blurry. On my Panasonic projector it is called "Frame Creation". On a old Philips TV I had, it's name was "Natural Motion". Sony calls it MotionFlow on their TVs. It works out motion-vectors by comparing the current frame and the next frame and essentially creates one or more in-between frames.

It ofcourse differs in implementation in Virtual Reality because the next frame is not known and latency demands makes it impossible to compare to the next frame so it is using, among other things, your head movement to predict how the next frame (that didn't arrive in time) should look like. Sony will have 120hz native mode in their upcoming Morpheus HMD but will also allow 60hz titles to upscale to 120hz and they are calling it "Reprojection".

I don't have Flyinside but quickly went in website and obviously it claim for user to have SDK 0.6 (instead of 0.7 not even released).


Saying that, I upgraded day one with SDK 0.6 and ED work perfectly fine with it. Did you try 0.6 on your configuration with ED?


Edit: and I just downloaded it (as I have FSX from Steam) and it give me the choice to download for Oculus SDK 0.6 or 0.5... And they say: SDK 0.7 supported soon.


Edit2: Mmmm OK, from the faq : "While you're free to try 0.6.0.1, I'd recommend using FlyInside with 0.6.0 or 0.5.0.1 for now instead." so 0.6.0.1 will probably not work

Edit3: Mmmmm OK, work perfectly fine with runtime 0.6.0.1! :) Off course need some polish (mouse pointer kind of capricious) and FSX go down to around 35 fps on my machine (need to tweak settings) but I was able to Fly (San Juan mission) and that's pretty cool :) Didn't know Flyinside so thanks OP for the information! :)

I have Flyinside running on 0.5.0.1 just fine (FSX Steam). Did have 0.6.0.1 installed but Elite kept crashing and all the VR demo's had judder. Uninstalled and put 0.5.0.1 back on and everything working and smooth. On Windows 8.1.

Thank you for giving an update as I was curious about this.
Do you know what kind of utilization you are getting on your CPU when you run the above?

From memory about 50-70% I have a pretty beefy PC (980ti etc) and setting frames to unlimited I get well over 100fps in medium settings. If I go too high (settings wise not altitude ;) ) I get crashes with dedicated scenery packs
