There was not much in it really anyway. Both cards were operating at framerates well beyond the 90/120 that the headsets will run at. Im still going for 6800xt (if I can get one).
Kind of what I thought, hoping Wednesday see's me able to get one then get back to racing.
Thanks, this sort of VR focused review is exactly what I've been waiting for. Kind of backs up my suspicion that Nvidia has the VR edge, but honestly I would buy either of these cards given the chance, as would most of us I imagine.
If you ignore ARK as an outlier they are fairly closely matched with a few wins for the 6800XT but falling behind on average. The 6800XT seems to struggle to match the 3080 in UE4 games specifically while beating it in Unity... unfortunately a butt ton of VR games are made in UE4.
The one that really throws the cat amongst the pigeons for me is the ACC result, because that’s one of my most played games.
I was all ready to go red this generation but given the majority of my demanding gaming is VR, I’m now having second thoughts.
Of course either card would be a substantial improvement over my 2070S... AMD generally seems to have substantial performance improvement over the life of the product (see 5700xt release perf vs now for example), is a bit cheaper, and has more room for overclocking but starts from a ~10% disadvantage. Decisions decisions.
I do wonder if the lack of performance specifically in UE4 might be a driver optimisation issue.
It's similar for me in that ACC is pretty much the only game I play. It's crazy when I think that I'm having to base every hardware choice I make around this one title!
@EsxPaul its an abusive relationship lol.
It’s such a pile of poorly optimised dog doo, (particularly in VR) but it’s just so good that I keep going back for more...
Have you tried it since the 1.6 update dropped? I’ve been waiting for my G2 so not tried it yet but apparently there were some small performance optimisations - notice any difference?
ACC and MSFS are forcing me to upgrade to a 5900X or 5950X earlier than planned too!

I did read a few reports of better performance since the update but I can't say I noticed any difference personally. I'm on a pretty old setup (5930k, 1080, Odyssey +) and am only getting 45fps on a good day, so probably not the best person to gauge any results!

Struggling a little with ACC. 90hz on the Index is giving me micro stutters, resolving it seems to be by switching to 120hz. I wouldn't say that 1.6 has made any difference.
The weird thing is that it doesn't seem to be struggling on frames. No matter how large the field of cars, they glide along with no ghosting or repro, it's just that stuttering issue. It's starting to grate a little when you compare ACC to anything else. 10 minutes later when you fire up AMS2 and you have it running all on ultra, all gliding along without missing a beat at 90 frames looking 5 times sharper than ACC, you just want to start throwing sharp sticks in Kunos's dirrection.
They seem to just throw their hands in the air and say, we can do nothing:/

Yeah they seem to palm off any performance complaints as “it’s just UE4, we can’t do anything” when there a ton of VR games running beautifully in UE4.
Very frustrating, I appreciate they are a small studio but the poor VR optimisation is a constant thorn in my side for what is otherwise one of the most fun driving experiences I’ve had.
Given my inability to pick up a 6800XT or 3080FE thus far I may have to stick with AMS2 and RF2 when my new reverb arrives...

Well i cured the stutters by limiting the in game frame rate to 90. Honest truth is it'll never look as sharp as the madness engine does, but my 9700k/3090 is running this at a pure 90 frames at 150% sampling, in game Epic VR without stuttering or frame drops.
Just had a mad bumper to bumper race around Zolder in the middle of a 6 car pack. The 3090 is feeling very worth it right now, but maybe i'm just still buzzing

Try turning off AA but upping the super sampling in steam to eg 200%, add some sharpening... turn down post processing effects to release more headroom if required.

I am happy with it for now, 150 on the Index looks ok. I was more concerned with performance which is now great, enabling me to be competitive again. I'll keep it in mind though because i'm sure when the G2 comes it'll be starting over again.
Lol - I am currently resisting the G2 at the moment as I think it may start the upgrade cycle off again.
Be interesting to see how the G2 native res compares vs index plus SS. The SS is more taxing overall so you may find things run better and look better on the G2.
Gonna wait for the next index headset.
Soldato
Most things in the Index don't really require SS, ACC being an exception. I remember having to downscale the SS when swapping out the Vive for the Index, there was visual tearing with the more demanding native resolution. That was on the 2080ti, i think there's a lot more overhead with the 3090 so hopefully it swaps nicely over.
Yeah well I mean if a 3090 can’t get you good IQ on it then nothing can...
If they don’t do any further optimisation work I guess we’ll need at least another generation of both GPU and CPU before being able to get ACC to really run truly well in VR.
The thing that concerns me is the devs may see the lack of players in VR and decide it isn’t worth their time optimising because not enough people are using it, when in fact I know that a lot of people actively avoid playing ACC in VR due to the poor performance. Build it and they will come!

That really is a generic trope. Right now it runs perfectly well on my system, the minor niggles it had performance wise on the 2080ti have been ironed out, no more odd stutters or frame drops. Sure it's not as pin sharp as PC/AMS2, but if looks are the thing it beats out all the rest including AC and it's heralded sol mod.
As for a lot of the noise that surrounds ACC, most of it comes from the Anti VR crowd in the hardcore sim racing circles, It's becomes a convenient stick to bash VR with from people that just will never accept VR.
Granted i get that it's poor performing, but lets get real, it gets bashed from all sides. Those on high end machines that refuse to accept the odd drop or stutter, those on 1060/70/80 that bemoan the trade off between it looking like total **** or dropping the frame rate through the floor, and as said the anti VR brigade that do nothing but patronise it with generic tropes like the above, while claiming VR takes them away from family life or prevents them from eating a 3 course meal while they sit there for hours on end in front of their triple screens while searching for that extra tenth of a second.
My apologies for the bit of a rant, but it's been a long time coming. I wasn't having a pop at you, just i get tired of that line.
I fundamentally disagree. It's not a trope... fact of the matter is that it's an absolute bear to run in VR compared to eg AMS2, Project Cars 2 or RF2 for example. It's great that you have it running well enough for you but you have a frikkin 1500 quid graphics card buddy.
It's still my favourite game of the lot, but despite a perfectly respectable spec I struggle much more to get good performance than in any of the others listed (all of which I also personally run in VR) and have to make sacrifices like not having blooming wing mirrors so don't go telling me I'm peddling tropes! I'm talking from my own personal and extensive experience with it and other games in VR, not parroting some ******** I read some guy say on a forum somewhere. I'm a long way from being anti VR and a long way from being anti ACC - it's a simple fact that it's just very poorly optimised to run in VR relative to pretty much any of the competition.

+1. I've got AC, AMS2, PC2 and RF2 which I can run happily on my 5700XT, I bought ACC hoping I could do the same but spent about an hour messing around with absolute minimum settings before consigning it to the 'play when system is beefy enough to handle it' pile. Seems like it will be great, but not yet for me.
This thread has been hijacked by racing games, enjoyable though that is.
But re VR the original question still stands.
I will be building a new system in the new year. The main aim is getting the best experience for my Valve Index and VR games.
AMD seems to be the best bet re. CPU.
There are some benefits about pairing AMD CPU's and the new AMD graphics cards, and that seems like a win-win.
I'm not bothered about ray tracing at the moment as I think that will be next-gen+ especially re VR, and that seems to be Nvidia's selling point.
But the comments about Nvidia and VR have set me thinking. I've got a 1080ti and it has been faultless.
I was going to go all AMD, but are Nvidia GPU's that much better for VR?
