Hi just to jump in and for someone considering a quest 2 for this game. Would my system be good enough?
X2700 16gb 1070ti
Recommended spec for "VR" are: 2700X, 16GB, 1070, so in broad brush strokes you should be good, however as VR headset resolutions range from 1440p to 4k+, your mileage varies dependent on your chosen headset. They've recommended the Rift S for this (likely for no other major reason than it was what they used in development), which I assume means they're working their recommended VR specs based on 2560x1440, whereas the Quest 2 runs practically double the pixels at 3664x1920... this could be the difference between playable and non-playable FPS. Let's go deeper...
In the main thread there's people talking about their performance, and although it won't scale exactly linearly, it won't be far off. I did some fag packet maths for this the other day based off relative performance figures and guesstimated pixel count, let's see if I can recreate it here.
One user reported 160fps @ 3440x1440 with a 2070 super:
3440x1440 is 4,953,600 pixels vs the Quest 2's 3664x1920, which is 7,034,880. That's a 42% increase, therefore at that res you can expect a (rough) 42% decrease in performance, around 93fps. Now to compare the 2070 super to the 1070ti. This res, although not quite 4K, is closer to it than 1440p, therefore it is the most reasonable metric to use.
So, using a .7 multiplier against the estimated performance of the 2070 super, 92.8 * 0.7 = 64.96; 65 fps is the ballpark for what I'd expect with a Quest 2.
Obviously a severe approximation, running at max settings and using a relative performance figure based on multiple games. I'd guess you'd be able to squeeze at least 10fps out of turning some settings down and, due to the extremely high resolution, dropping a lot of AA (although, not being a VR user at all as of yet, I have no idea whether VR shows aliasing more than flat games). That would bring you to mid 70s, which is the most you'll get from the Quest 2 at the moment without using special test builds of VR desktop (as far as I'm aware, someone else is likely more knowledgable on the experimental 80/90hz modes).
