Видео

I'd need to re-watch it myself to be sure, but I don't think anything covered in this video is necessarily out of date. The fundamentals of frame timings, framerate and reprojection are all still true to this day as far as I'm aware. There might be some changes in how some of those things work in Virtual Desktop for example, but even then it's all pretty much the same.

@@ImmersedRobot Thanks. I have asked some questions over at the Steam forum to see how this app has developed with not just the use of SteamVR but also with a Oculus headset, the Quest 3 in my case.

It's been so long since I've used this mod that I'm not sure what to suggest regarding the resolution issues you're having. I struggle to get it working properly now due to the fact I own the Rockstar Launcher version of GTA V and the, now unsupported mod, seems to have major issues working with that version - even when rolling back updates etc (I wish it did). Sorry I can't be more help, but thanks for the comment!

@@ImmersedRobot It's all good man! I'll keep looking around and see if anyone else is having this issue, but honestly it's still fun to cruise around at 1080 lol. Ah man, that sucks that there's issues with the rockstar client version. i have it on steam and just checked another video on here where the guy had create a ZIP folder containing all the files, that i literally just pasted into the game's folder. i can give you the link to that video if you want to try those files? and it's all good man, i appreciate the response!

@@EubyGamingRES I'm pretty sure I might have already seen the same video a while ago, but I just can't get it to work on the non-Steam version. I'm sure there's a way, and maybe I'll look into it deeper at some point in the future. But thanks for the offer.

@@ImmersedRobot ok cool, no worries man. At least the game usually goes on sale for cheap, if you ever did want to grab it on steam and jump back into it lol

I am seeing people recommend setting it to 68% to get the 1.4 scaling properly matched on PS VR2. Is this correct?

@@BartCunningham it’s difficult to know for certain what the PS SteamVR app is doing behind the scenes, but I would assume that the distortion algorithm they are using requires 1.7x supersampling in order to bring it back to native resolution. That’s the only explanation why 100% shows as 3400x3400 per eye. But I can’t be certain of that, and regardless, that is a very demanding resolution for most PCs.

@@ImmersedRobot Thanks for the response. I will probably leave it set at 100% but may turn off motion smoothing. Alyx seems to be doing okay with it so far. I am running a MSI Katana I9/RTX 4070/64GB laptop.

Motion smoothing off was a worse experience. Obvious low frame rate with it off. Much better with it on.

@@ImmersedRobot So does the HMD manufacturer provide steam with the intended values? How does steam know what 100% should be for each headset?

You can go through OpenComposite, although how well that integrates with the direct OpenXR DFR integration with Elite I’m not sure. I tend to stick to OpenVR for Elite as it turns out.

I'd love to have that option in there too. I feel it could be slightly more aggressive without being that noticeable too.

I'm not hugely familiar with Subnautica (although I've played a few hours of it in VR) but here's the Pimax Crystal DFR spreadsheet regarding game compatibility: docs.google.com/spreadsheets/d/16GNwXAVCjUF9vCW6ubiUPQT00hZ7hRT5K_sbO6P9nYc/edit?gid=0#gid=0 You should be able to load it directly from SteamVR and the DFR should be present via the Pimax client in that way since it seems to utilise the in-built OpenVR DFR implementation.

If you have dynamic foveated rendering from eye tracking enabled and the game supports OpenVR DFR the you still want to select one of the foveated settings (I use aggressive). Although it says ‘Fixed’ this was just an oversight in the software I believe. This used to be the case at least, but I’d need to go in and check if this is still the case.

Ok I got it. But what shall I select if the game don't support Eye tracking? Do I keep it off?

Sorry, I’m not sure you’re being serious or not. But assuming you are, then what I’m showing here is Elite being played on a PC and streamed to the Quest 3 over wireless connection. Elite does not have a native Quest version.

100% is effectively rendered at 140% behind the scenes anyway. The line has nothing to do with it, and simply indicates SteamVR’s recommended resolution scaling for your system.

I picked one up again recently due to the low price right now.

I agree that price would be perfect. It just doesn’t seem possible for them to reach that while making any viable profit unfortunately - at least that’s what I can only assume due to their standard pricing.

Yes, with those features (which most people are probably advised in getting anyway) then the price does jump up to make the overall deal a slightly higher tier. It's still probably the best dedicated VR system for the specific types of simulation games I'd only ever recommend the Crystal for regardless. And in that recommendation, the controllers might not be necessary for all - especially, as I say, sim gamers. Although I love my Pimax Crystal, I would never recommend it as an 'all-rounder', and I stand by that for my own use-cases.

Sorry, I'm not certain what you're asking. Are you saying 45fps is too low? It's running in reprojection in order to give consistent performance with that framerate, which is less than ideal, but sort of necessary.

Without being an expert on the network-related bottlenecks of delivering frames to a headset, my guess would be, no (at least not in showing dropped frames on monitoring software). Wifi issues will certainly manifest in perceived stuttering for sure, but when monitoring via fpsVR, I believe that relies on information from the frame processing of the PC itself. So if fpsVR is displaying a dropped frame, then that is a result of the PC itself dropping the frame, and that has nothing to do with network issues (as far as I'm aware). Virtual Desktop's monitoring tools seem to combine this in various ways to provide more information from network-related issues, so that might provide extra information.

@@ImmersedRobot thanks a lot! Yeah I saw something about that in Steam forums, for now will just do subjective testing using new WiFi 6 AP

This sounds like you’re simply not hitting native framerate. What are your system specs, headset model, and connection method?

@@ImmersedRobot I have a 11900KF, a 3080ti, 64gbs ram, and Windows 10.

the rest of their gear looks good, the rear comfort pad and even the hand cushion pads they offer. This? this looks cheap flimsy in build quality, small flat cushion, and the audio? yeah i don't expect much there. Your better off paying for a quality pair of headphones than these overpriced pads. If your expecting quality audio and build quality here your seriously looking in the wrong spot =) Grossly overpriced for the audio quality and build. Not sure why any serious person would consider these a viable option. Use the money and save for a better headset.

90fps when viewed via RUclips's 60fps will never look perfectly smooth. For this reason, I show performance data to illustrate how it would feel in a headset with a 90Hz refresh rate. 90fps at 90hz in the headset will be perfectly smooth. You'll notice that the 120fps footage looks very smooth, this is simply because viewing RUclips's 60fps video on a 60Hz monitor multiplies perfectly for footage captured at 120hz/120fps (each frame of video is off course retained skipping every other frame of captured footage, making it appear smooth). 90fps footage will never appear smooth on a 60hz monitor/60fps video unfortunately. This is why ideal footage for VR game trailers etc will be captured at 60fps (or 120Hz/120fps) rather than 90fps.

The room calibration on the Crystal is confusing to say the least. I don’t even bother setting it up. I just sit down in MSFS, Elite or whatever, then hit the ‘recenter’ key in the experience I’m playing. I’d clarify this with Pimax, but I’m almost certain the room setup is not necessary at all.

This is not a review. It’s me trying a VR space game which passed me by.

Why would you ask a youtuber that? lol

@@mrlost117 “RUclipsr” lol

I've been told that I will receive a review unit of the Crystal Light, although to be honest, my current work schedule means I might have to turn the offer down due to limited time to make videos. However, if I do go ahead and review the Crystal Light, I will request an SMAS version for this very reason. I'd be interested to know how good the sound is myself, and actually wish I'd tried that version at the Pimax Roadshow event I attended last week. With regards to the DMAS headphones on the Crystal, I'd personally rank them very close to the sound quality of the Valve Index and the Reverb G2. There might very well be a small difference in sound quality, but I struggled to tell the difference. The DMAS is very good sound quality.

@@ImmersedRobot Thank you for the reply Gary, the difference you experienced with the DMAS possibly not being quite as good as the Index is more than likely dependent on what amplifier and DAC a particular HMD is using to power the sound solution. In example, I have a Pico4, no 3.5mm headphone jack on that HMD, I bought a Ugreen USB-C to 3.5mm, I used the DAS headphones with 3D printed adaptor and once plugged into the Ugreen adaptor... the sound is simply amazing, much better than any other HMD I've ever plugged the DAS headphones into (Vive, Rift-S, Quest 2 and 3) so I'm thinking whatever goodies they pack into that little Ugreen adapter makes the DAS sound so much better making me realize the DAS are actually really good headphones, the DAC in VR headsets blows dead goats at midnight.
