VR Discussions, Questions & Feedback

Hi No problem, I will share some settings.

But about the motion smoothing vs motion vector. To my knowledge there is no difference in the sense that only motion vector is ever used by WMR, there is (I believe) no way to use a different smoothing technique.

The way it works (again, to my knowledge) is that in the WMR settings, you can use a setting that is based on how you set it in steamVR settings, so if you enable motion smoothing in steamVR, it will use motion vector (The WMR method for smoothing).

Yes, 100% render scale is impossible to run 90fps. I use 75% (Edit, I think it is more 60%) or so (steamVR says about 2500x2500 pixels per eye). You can (and really should!) then use the sharpening tweak for a vastly sharper image. Probably it will look as sharp as 100% with the right setting (I use 2.0 sharpening) unless of course you already applied the trick.

For other settings I have MSAA on medium and then a mix of low/mid/high for the other settings. Bur for clarity I am very happy.

So to summarize my most important settings:

- steamVR approx. 75% (2500x2500) (Edit: I think this is more close to 60%)
- sharpening applied with graphicsconfigdx11 tweak
- MSAA Med
- Other settings a combination of low (particles grass shadows), Med (Track) and HIGH (mostly the texture stuff)
This works 90fps all time full grid except maybe at a start at SPA for a very brief moment it can dip. Night and rain is another story...

Hope that helps, but of course you must choose a setting that works for you. It is subjective.

This is all on a 5800x / 6900XT / 32GB

 

I agree. Although I have a Vive Pro so only have SteamVR motion smoothing for my option, it does not work well with AMS2 at all. It still looks stuttery but still has artifacts. Its very strange because SteamVR motion smoothing works fantastically well in titles like ATS2, MSFS and DCS. These can look smooth even at frame rates as low as 30fps.

As a result I don’t use it for AMS2. Luckily its only night racing that I cant always get 90fps (with my preferred graphics settings which admittedly are pretty high) and only on certain tracks at certain places so don’t need SteamVR motion smoothing for AMS2. I hope they optimise night racing at some point because its worse than PC2 (which I no longer play).

 

So what is the story with this madness engine? This VR night performance stuff is not getting fixed, nor are e.g. scrollable replays. Is any company still supporting this engine or is it end of life since PC2 and AMS2/Reiza just uses it and develops content?

 

End of life? AMS2 hasn't even got started yet, there will be at least three more years of support I reckon. Things are moving slowly but in the right direction.

 

My Steam VR setting "Nice quality"

 

Do you have a quantum PC or something?! How the heck are you running those settings?!?!

 

By sitting in the pits it appears. I'm guessing performance will take quite a hit with other cars and weather - looks like he is already dropping frames before even hitting the track.
BTW - increasing MSAA to high has a bigger effect on image quality than running pointlessly high SS

 

MSAA to high kills my performance. Night and rain I probably drop SteamVR SS to 250. It hold 90fps even racing full field. I am Also using FSR for Open VR found here

Here are my system specs, Nothing special FSR for Open VR helped the most

Pit rd, Frontstretch usually has the biggest impact on FPS
"looks like he is already dropping frames before even hitting the track"
The dropping frames is an Nvidia driver issue, hopefully they get it sorted
It has been happening in all my games lately even with low Steam VR SS
"MSAA to high has a bigger effect on image quality than running pointlessly high SS"
I would much rather have Clarity down the track and no blurriness over MSAA to high
image quality. I can read the Label on my fire extinguisher
This was just to show what is possible... I see a lot of Vr users using Steam VR SS @ 100
The higher you can get it, the better the clarity. Hope some try it and see the improvement. See you all on track.. Keep tinkering see whats possible. It's only going to get better!

 

Thanks for adding some additional details. Perhaps it’s worth trying FSR again. However, I tried installing it once and AMS2 would crash upon launch. Also, I think I read that @NuScorpii did extensive testing and basically determined it wasn’t beneficial overall to use FSR (he’s the one that ported it to AMS2 I believe). Anyway, I’ve just been using that as an excuse to give up on it, but I think it’s time to get it working and try it out.

 

Mine crashed also till I found the AMS2 version, There is a 1.1 now but not yet for AMS2.. I get about a 30% gain using it. Here are the links for AMS2 1.0

 

I have a Reverb G2 and the headtracking doesnt always work properly.
Sometimes when Im in my car and I move my head irl the cockpit moves along with my headmovement.

For example when I try to look back and move my head forward and turn my head, the whole environment moves along with it, making it impossible to look back properly.

I think I remember this happening in ACC too so it might not be an AMS thing. But hoping someone knows whats going on with that.

 

That has never happened to me with Oculus Kevin.

 

Wmr drops back to 3dof tracking (rotation only) if it doesn't think it has usable position data. Perhaps it's just this? Maybe where your rig is there's not enough light or something for the tracking cameras to work with?

 

Likely I had the same. I was utterly puzzled about this i thought it was some weird setting but it was just the amount of light in the room.

 

Ok thanks, Ive thought about this before because Im sitting behind a super ultrawide that might be blocking a lot of the light from reaching the sensors.

Ill try adding a lamp somewhere and report back.

 

Usually when this happens to me on my G2 mid race I just pause then slowly look to the ground then slowly up and then I sweep my head from left to right slowly so the sensors can pickup the background again. This might reset your positioning which just means you have to hit the centering button again.

Also this can happen if the lights are too bright or a window is close by and too bright.

You can test your lighting by just bring up the flashlight app while in WMR and you can see if your lighting is washed out or not which will hinder tracking.

 

Adding a lamp won't help. Although some bright lights (and mirrors) can negatively affect lighthouse tracking they do not require any ambient light - they emit (non-visible) light and track by sensing this light being reflected back. I regularly use my headset in near darkness with no issues. If both your lighthouses are on the other side of your monitor, consider moving them to a position where they have line of sight to your HMD.

 

WMR doesn't use lighthouses, it uses cameras on the HMD which require some ambient light to function properly

 

That sir is truly remarkable (if not unbelievable )

So basically you've maxed out settings and getting 90fps by rending at an equivalent of 90% of the normal G2 res (approx 2900px wide) .... I'm gobsmacked! I need to understand how to do this.... would you mind sharing any other settings? Nvidia control panel changes? Windows Game mode? Hardware accelerated GPU Scheduling?

I've a 3090/5950X and can't max out at 45fps motion smoothing in all conditions at 80% SS, never mind what you've achieved!

Show us the way and you'll be godlike!

 

After a lot of testing I *think* I have finally nailed down the ideal combo of graphics settings within the "Performance" section, which I will share ASAP. Now I'm curious: What do you find to be must-haves in the "Visuals" settings section? Just wondering where to focus my testing/experimentation first. Thanks!
