VR Discussions, Questions & Feedback

Since the last update, centring the VR view puts my head on the centreline of the car (or thereabouts). I've tried running AMS2 in Oculus and Steam modes and they're the same, and I've re-centred the view in Oculus and Steam, but that changes nothing either. Other games seem unaffected.

Any ideas?

 

I also have huge discrepancies. I play the game sometimes and I think it’s really good then next day it’s terrible. I play on rift s and have steady 80fps but the visual quality varies significantly between sessions resulting in me messing around with various settings only to find next day I have to change them all back again. Looks like I’m not alone

 

Has anyone tried the new Porsche in helmet cam view? I swear there's no performance hit using it. Maybe the big performance hit using the helmet cam in other cars is tied to the visor being in front of the eyes whereas it's not there in the RSR.

 

Sounds like you need to cycle through the cameras to get back in the driver's seat.

 

Yeah, I realised that yesterday, but thanks anyway. The strange thing is that I've only ever used cockpit view, so didn't even have a button mapped to change it, but for some reason the camera changed from cockpit to something almost the same (it was in the cockpit, but not the cockpit view, and I realised because it drew the driver's head, which it shouldn't do for cockpit view).

 

Anyone had success with the OpenVR FidelityFX super resolution mod?

I've used it to fantastic effect with ACC, but on AMS2 it crashes on start with the modified .dll

 

Same issue here. I think I read on the GitHub page that several things need to be modified in order for it to work with AMS2, and the effects were not worth it. Just one opinion though of course.

 

Have you guys tried the version within this thread?
It worked for me but; later decided just going with default oculus one is smoother besides no huge performance deal.
FSR for OpenVR

 

No but NuScorpii had helpfully linked me to it on reddit earlier... haven't had a chance to try yet.

Cheers!

 

Anyone with 6900xt and G2 that can share their settings?

Currently on 2500*2500 per eye, MSAA medium and it's consistent 90 FPS on all tracks with full AI Grid.

However night crushes FPS tremendously.

In addition rain also crushes FPS, but it has again to do with lights. Whenever there are many cars behind you the FPS suffers. The rain itself doesn't matter that much.

It seems there is a "bug" with cars shining inside your car or something. I hope they one time fix it.

 

I just experimented at Long beach and found the same thing.

1 lap night race, full grid starting from last place. If I follow the AI around in last place I get 80+fps for the whole lap. If I overtake just 2-3 of them into T1 I get 40-50 fps for the whole rest of the lap.

Shadows are off and pretty much everything at min except texture resolution.
Turning mirrors off makes no difference.
Switching to different cameras makes no difference.

 

..same here

 

Check Nvidia control panel! For some reason, when I went to the AMS2 executable (if you have Nvidia) mine was set to integrated graphics. Which by the way, I have zero clue how it got like that! Must have been some funky driver update or something. Set it to Nvidia processor. Or whatever they call it in the control panel! Good luck and hope thats your issue

 

Potentially dumb question, but I won’t be near my PC for the next few days so figured it was worth asking to save some time poking around in the UI:

Using VR, is there a way to save a replay and have it playback as if you’re onboard again in VR? I’m interested in creating a benchmark to evaluate the performance impact of different graphics settings (external graphic settings specifically). Thanks!

 

I dont think so.

 

Please add support for Pimax!!! Paralell reprojection is fps killer

 

Benchmarking VR is possible but it's a little fiddly.

Once you have a replay you can set it to cockpit cam and play it. For benchmarking you need the head position to be constant, so put the headset on a desk, sit something inside it to activate the proximity sensor and hit your recenter button before each test.

To record benchmark stats I use FCAT VR from nvidia. It's not too different to using FRAPS if you're familiar with that.

You specify how long you want to benchmark for and which key starts the benchmark. Once configured click play on the replay then hit the key to start fcat. When it's finished it will output a spreadsheet of frame render times (frame start and frame end times) and a bunch of other info. Rename the spreadsheet to something meaningful, change your setting and repeat.

As long as you're always benchmarking the same section of the replay and your headset is properly centered for each run you should get repeatable results.

The fiddly part is comparing results. FCAT will only give you a dump of frame render times. It's up to you to calculate average/median frame time, graph for comparison or convert to fps instead of milliseconds per frame if that's what you want.

 

@DarrenM fantastic info! Thanks!

I’ve spent probably a dozen hours or maybe two dozen over the past week trying to eek out any performance gains I can with my system, and long story short, I found that the “Motion Vector” setting for the G2 is the best way to go (as was mentioned earlier in this thread). Still super perplexed by a few of AMS2s behaviors in VR, and I think there is a lot of room left for optimizing from Reiza’s side, but at least the game is playable and looks fantastic now! What a journey to get there though!

 

Best way to go to achieve what?

If your system is capable, 90 FPS can very easily be achieved and you get rid of reprojection artifacts and some motion blurriness.

However if your system is not high end I agree it's a good compromise setting.

Must be said though that rain and night racing are unachievable at 90fps so there perhaps reprojection can work.

Why do you specifically mention "motion vector"? The setting in steamvr is called motion smoothing, which basically just engages motion vector when setup correctly.

 

My last message was definitely a bit vague, so now that I have time to clarify:

I've found that the "Motion Vector" setting within the dedicated Windows Mixed Reality HMD settings app within SteamVR app provides the best motion smoothing and most satisfying overall visual experience within AMS2 (Note: I'm referring to Time Trial mode specifically, since this is the only game mode I currently use). This setting, directly compared to Steam's Motion Smoothing, is far smoother for whatever reason (Steam's is basically unplayable to me). I have no idea why this is the case, the difference is extremely obvious when switching back and forth between the two though.

I am not sure why my signature wasn't showing up earlier, but my system specs can be found below. I definitely don't have the highest-end machine, but it is solidly in the upper-end of the spectrum (I think). Testing hasn't revealed any obvious bottlenecks, but I am always open to suggestions on hardware changes. That being said, I haven't been able to achieve 90 FPS locked in Time Trial mode (using Spa as a test track) even after turning all graphics settings to low. Huge caveat: This is with SteamSS set to 100% per HP's own recommendation for the G2 (I will attempt to find the article later). This article, by one of their product engineers, basically states that 100% SS in SteamVR should be used with the HP G2 at the minimum if at all possible, and that in-game graphic settings should be adjusted to make FPS suitable thereafter.

I am completely open (and eager) to try different settings though to compare to where I've landed so far. Do you have some settings you can share? Also, any tips for tweaks to other items (Windows, Nvidia Control Panel, MOBO BIOS, AMS2 doc edits, etc) are more than welcome. I've tried quite a few things, but I am certain I have not tried everything.

Thanks for the response. I look forward to experimenting with any suggestions you can provide.
