AMD 9070XT VR good idea?

@Ravenger I spent the day installing and playing the Mad Dog Overhaul for Skyrim VR. Wanted to try it on my 9070XT. There is a warning before install that you must have 32GB of Ram and must set the Virtual memory to 40GB. I don't have 32GB of Ram(only 16) and didn't change the virtual memory. And it runs really well. Spent a couple of hours there just walking around. Haven't even made the first town yet. It is very, very pretty now. In a way it's almost too pretty. I think it's too "clean" for Skyrim, I feel it should be grittier graphics if you get what I mean. Still it's stunning to look at. Might do another playthrough now :)

My settings in Virtual desktop.

Resolution - Godlike,
Runtime - Steam VR
Target FPS - 120
Codec - AV1,
Bitrate - 200Mbps
I have also turned on the video Buffer and the Super resolution option.

In Steam VR I am using custom resolution per eye of 100%

The only settings I changed in game were the ones that the instructions said to change, the dynamic resolution to off and the super sampling to as low as you can go.

I was going to order another 16GB of Ram for my PC, but based on the performance so far, I don't think I will bother. It has run perfectly so far and while it has dipped below 120FPS a lot, it hasn't really been noticeable in actual gameplay. But I think I will try it again with 90FPS just to see.

Same here :) I'm however intrigued to see what conclusions someone with more of a clue and more patience (Melmac!) comes to :)

:cry: :cry: Sorry!! Got distracted today with installing a Skyrim Mod and didn't do much testing at all!! See my post above.

I think you will have to have the most patience waiting for me to come back with results :p

Hehe, you've already given me some brilliant steers. Enjoy your modding!
 
Did a little more testing today in Fallout 4 and Skyrim VR.

Virtual Desktop with AV1 looks far better than Airlink with H.264 and H.265.

It's looking more and more like AV1 with Virtual Desktop is probably going to work out the best for most people using the 9070XT.

One caveat though. Guy Godin, who is the developer of Virtual desktop has noticed that H.264 and H.265 have high latency when using Virtual Desktop. He has reported this to AMD. So things might change when AMD look into this.

Another thing, is I am testing using Adrenalin 25.3.1. AMD released a hotfix/beta driver 25.3.2. By reports I have seen on various forums, this improves performance in VR on the 9070 cards.

Fallout 4 VR is something I'm interested in, prefer the atmosphere and environment to Skyrim VR tbh, I dearly hope we get more large scale open world games like these eventually.

By the way I've yet to even unbox my 9070 XT yet, it could be a brick in there for all I know lol, going to test drive it literally within a few days with Beam.ng which was so-so on my 3070 then move on to FO4 probably.

Btw there's something I came across called Opti-scaler for AMD cards that allows FSR usage in games which only have DLSS compatibility, not sure if it works in VR.

FO4 VR can be improved by software. Use Virtual Desktop's VDXR runtime, and if on Meta headsets use OpenComposite to convert SteamVR to OpenXR. You get about 30% performance improvement by that.

Also try the Mad God Overhaul Classic modlist, which for some reason runs massively better. I can play without reprojection now at 80-90fps.

Similar in Skyrim VR where for the first time I have a massively modded game (FUS modlist) running in Godlike in Virtual Desktop with no reprojection.

Caveat: I have a 4090 :p, but even then I had reprojection before I switched to Virtual Desktop VDXR + OpenComposite.

Edit: it's been a while since I messed with OpenComposite etc. May I ask @Ravenger : so I set it to VDXR in VD (I can do that), and I also go through the slight riga-romole of using OpenComposite to bypass SteamVR (I know it's not difficult, it's just been ages)? I'm not expecting miracles with a 9070 XT but a 30% boost would be very welcome :)

Also I'm getting very good results using H264+ in virtual desktop at max bitrate (400mbps on Quest Pro, 500 on Quest 3).
A good router is essential though to maintain those bitrates.

Tbh I tried a 6E router last year and found it to be no better than my 5GHz ISP issued router although I think iirc I used AV1 with a 4090 at 200Mbps.

Depends on how congested 5Ghz is, how good the router is, and how many devices are also using the 5Ghz band.

I found a 6E router to be a massive improvement as I could increase the bitrate, and isolate it from my other devices.

But for some people 5ghz will work fine.

If it's a decent ISP router and wired back to the computer and you can maintain the full speed wireless connection, then there will be no difference. It's just marketing fluff.

It makes me laugh when people claim that they noticed a big difference when moving from a wifi 5 router to a 6E router. Especially when using it as a dedicated router for the Quest headset. Even Guy Godin, the developer of Virtual desktop says there is no difference, a couple ms of latency at best!!

The main difference for me is I could massively increase the bitrate. That didn't work even on a decent 5ghz router.

Also the Pro controllers are subject to wifi interference. Using 6 GHz helps with that in my experience.

i dont suppose you tried with a wired connection at all? i.e. network cable

I have a 1GB (could be 10GB, not sure tbh) ethernet cable straight from my pc to my router, then use my Q3 within about no more than 7 foot away from my router with a line of sight between them. honestly it does the job fine.

It won't be a 30% boost by using Opencomposite. If you get 10% you will be doing really well. It also varies by game.

Do you want to install it per game or do you want every game to use it? If it's by game just download the openvr_api.dll from the Opencomposite github and replace the ingame version with the one you downloaded. If you are running games with mods, using opencomposite might mess up some of those mods.

as i said you havent been swarting and a gentlmen is always polite and considerate of others.
your always encouraging others in game, giving advise, and playing for fun not to win, while giving the others some competition to contend with
