Asynchronous Spacewarp - Big Improvement?

I played a bit with this a bit too and recorded a video, although the effects are only apparent in the VR headset. GTX 970, Elite 2.1.


It has to be said first, and correct me if I'm wrong, but it doesn't appear that we can gather much information on the ASW performance other than visual observation. I can fire up the oculus debug tool and see the app's delivered framerate, in addition to a "performance headroom" but I cannot see how effectively the ATW or ASW is filling in the gaps.


I initially tested planetside with supersampling and so on, and couldn't really see anything interesting. I was trying to move my head back and forth, provoking judder, but when framerates are high enough, the quality loss is not really that noticeable by just moving my head. And when framerates are really terrible, like consistently below 45 fps, not even ASW can eliminate the judder.


So I flew instead to an icy asteroid ring, switched from VR High to Ultra settings and observed how it was flying through the asteroid field. No supersampling enabled, so the resolution was 1280x768. In this area, I got 50-60 fps natively from ED. Not enough for comfortable VR, and extremely noticeable when things are moving past you, or in this case, me moving past icy asteroids.


When objects are translating across the field of view, you get this juddering effect like the objects are skipping across the screen. It is especially noticeable in VR since it creates a stereo mismatch. One neat thing though, is locking the framerate to 45 fps, still no ASW. The game can deliver 45 fps consistently at Ultra settings. Great! And I thought 45 fps locked was quite nice. Sure there is some ghosting on the icy asteroids flying past, but overall pretty comfortable. But then the magic happens, switching on ASW. The game still delivers 45 fps, but ghosting on the icy giants disappear, with crystal clear specular highlights. I did see occasional judder, but I don't think I would find it annoying.

I'm not much for a youtuber so apologies for the inner dialogue-style :p


And xbox controller is hard... I'm used to HOTAS, but that's stored away at the moment. Time to take it out again now that graphics have been upgraded for free!
 
MASSIVE improvement! I just ran on Ultra, everything cranked to the max, including 2.0 SS (on my OC GTX1080) and it was so smooth and clear! I've been kinda hating on VR for Elite because it just looked terrible to maintain 90fps, but this....this truly changes everything. I'm actually shocked.

Not a chance mate. That or you are ignoring all of the stutter outside of your cockpit or pulling very slow pitches or rolls.

It's too bad this doesn't seem to work on GTX 780. Not sure, but for now seems everyone using GTX 780 gets an error:

ASW Disabled, reason: 'OVR Error:
Code: -3000 -- ovrError_Initialize
System error: 8 (8) -- Not enough storage is available to process this command.
Description: Encode Session Initialization failed

Time to hit the local computer store perhaps(?)

Negative on all accounts, I even took the ole Vulture out to a HIRES to test it in full-out asteroid dancing combat mode. Are you sure you enabled it correctly?

I also tried it out on Project Cars with everything set to High while racing in an F1 car, no issues.

I'm well aware of what it looks like to start dropping frames, I've been tweaking my settings for the past couple months trying to find the sweetspot between smooth gameplay and decent visuals. ASW has been night and day in my experience.
 
I can run on VR Ultra, using a GTX970 and an i5 4690 at almost no judder. Turning Ambient Occlusion a little down does the trick. This game looks incredible now in VR... much more than before... awesome piece of driver technology, that Oculus came up with.

I tested inside a space station, on a planet surface and in space. Will test rings and neutron stars tomorrow, as i dont have time right now. But man, this is a game changer for lower spec hardware...

I think this is the key... a lot of owners with lower spec hardware are reporting tremendous gains, myself included. and you're dead right, the game looks so very beautiful with graphics options turned on/up.

Another GTX 1080 user chiming in, I can totally back up what you've stated, though I haven't pushed SS all the way up to 2.0 yet (settled for 1.5 with max settings for now). As you said, it's literally "shocking" what this feature brings to the table. Utterly amazing.

Ok - I've heard enough to give it a try myself - although on my ancient rig I don't expect too much.
 
Stupid question. How do I figure out which run-time I'm on? Do I need to install the SDK too? I'm in the same boat as andysonofbob. I've downloaded the 1.8 OculusSDK, but there's no install or setup file (I know the to use the debug tool), and the link provided doesn't give any kind of install instructions.
 
No, you don't need to install any SDK related stuff. Open up your Oculus application, go to "Settings" -> "General" and scroll to the bottom. It should tell you which version you're on. The app updates automatically, so it should say "1.8.0.277202 (1.8.0.285271)".
 
The runtime is updated automatically. Start Oculus Home, go to Settings -> General, and at the bottom you should see "Oculus App Version 1.8.xxx"
If you've added the registry key and made AswEnabled true as described here https://www.reddit.com/r/oculus/comments/56af3t/detailed_stepbystep_guide_to_enabling_asw_through/, the service should be restarted. When the service starts, it will log the status of Asw in the log file located at C:\users\username\AppData\Oculus\Service_[datetime].txt

You should see a line like this:
08/10 13:49:51.633 {INFO} [VirtualDisplay] ASW Enabled

If you don't see this line then something is wrong :)

The debug tool is not used to switch ASW on or off, it is only used to add some performance information overlay in the game. Start the debug tool after starting Elite and select Visible Hud: "Performance".

Thanks. I didn't notice a difference between CTRL-1 through 4. I should probably double check my regedit file and do a restart.

Check in Oculus Home/settings/devices/general. It is at the bottom of the page. If you are set for auto update you should already have 1.8

Must say being able to crank everything up really makes the Beta look great. Go visit Earth with everything cranked, check out hangar in Gorbechev looks beautiful and runs perfect except for an occasional skip happened 3 or 4 times over 2 hrs.

I started the performance display from oculus debug tool and it shows fps dropping from 90 to 45 when I switch from ctrl + 1,2,3 and 4. You might bring it up to check if it works on your pc.

I had a hard time noticing the difference between locked at 45 fps with or without asw and I'm not sure I've done it right tough. I feel both are equal and I rather prefer 90 native fps. Especially while driving on a planets surface. I don't experience asw as smooth compared to 90 fps.

My experience in elite increased in quality after I used the performance hud and noticed I had atw being very active. Dialing down options to having 90 fps with a bit of headroom was very important. This was with atw only.

Ive tried asw with elite, but not convinced. I'll hold of judgement until I've tried it more and double checked my registery "hack".

This is on a i7 6700 and gtx 1080.
 
Dunno if this is worth bothering with tbh. Since v1.3 and ATW i got a massive boost fps in Elite. Able to run VR ultra no problems (albeit with a couple of settings slightly lowered) and with either 1.3 or 1.4 SS (oculus debug tool) Only very minor minor judder in stations occasionally.
