1080 Ti w/ 4770k - Rift S or Reverb?

[Cavemanhead]

I had my heart set on a Reverb but I'm thinking Rift S now after closer examination and evaluation of overall satisfaction if you have less than top end HW to drive it...  Agree?  I've never done VR before and I'm assuming I'll be very pleased even with the Rift S.

 

Thoughts?

On the CPU you will need to overclock it to have better results. CPU wise the Rift-S run at 80Hz versus Reverb 90Hz (there is also a 60Hz mode, I think some people use it with good results).

The 80Hz will demand less to the CPU (and GPU) than the 90Hz mode.

 

On the GPU, a 1080Ti is more than fine for Rift-S and just fine for Reverb, although depending of your settings you will need to activate motion reprojection to don´t miss any display frame.

 

I have tested the Reverb on IL-2, but not the Rift-S. But I tested deeply the Rift-S at my work.

 

I think the Rift-S is more comfortable than the Reverb. In addition the Reverb has a very thick and rigid cable which is a bit annoying (some people found solutions for that).

 

With the reverb you will need to run the steam app "WMR for SteamVR" and also SteamVR.

With the Rift-S people can use Open Composite and bypass the SteamVR.

 

Being your first VR device the Rift-S could be the most easy choice for you (cheaper, better tracking, better fps for same settings). But hey! the Reverb visual definition is pretty darn good.  ?

 

There is some through lenses screen captures in others threads in this forum.

1080ti is good for 90 FPS in the HP Reverb at 100% rendering. The image quality of the reverb is better than the Rift-S. Coming from a Rift CV1 I vote for the Reverb. With the Rift I returned to other games and monitor play. But with the Reverb I am always looking forward to the next takeoff in VR. It is amazing.

Chili, I've just seen the Reverb is on sale for Cyber Monday week, I can get it for CAD$749, with free return if I don't like it. So I think I might grab one, just to see if it's worth it over the Rift S.

 

Before I do that, I want to run supersampling on my Rift S to match pixels for the 9.5 million that the Reverb has, to test my rig (8086K-5.0ghz, 2080). I know you have a spreadsheet but I can't find the right one! What OTT pixel density do I need to match a Rift S pixels to Reverb pixels, please?

@Alonzo you will love the reverb.  believe me, its a massive improvement in clarity over an index at 10.5 million pixels on IL2. So it should blow a rift S out of the water (reverb is 9.3M pixels native but its WAY more clear than index)

[Alonzo]

Found it, I think:

 

 

1.4 PD is too much, 1.3 gives 9,892,746 pixels, close enough to the Reverb's 9.5 million. So I think I want OTT 1.3 pixel density to 'emulate' the amount of pixels I need to drive for a Reverb at native resolution. 

 

Edit: Spreadsheet link if anyone's interested.

Whether you have the Rift S or the Reverb, no matter what your GPU is, you won't be able to maintain 80 Hz or 90 Hz with this CPU unless you are at high altitude and you have at most one plane on sight. At least that's my experience with a i5-4670K overclocked at 4 Ghz.

 

When you drop under 90 Hz on the Rift, you fall at 45 Hz, which induce a pretty ugly "ghost effect" on other planes, but you can live with it. It is when the frame rate drop under 45 Hz that it becomes a nightmare. Unfortunately it happens to me, which is why I plan to update soon.

 

With the Reverb you will drop (a bit less often but that will happen) from 80 Hz to 40 HZ. Whether 40 Hz is significantly worst than 45 Hz, I don't know.

Be aware that the Rift run at 80Hz and the Reverb at 90Hz. So you will need to take 1.3 and divide by 80 and multiply by 90.

In any case, this is just an approximation to load your GPU since the WMR software might not run as your Oculus or OpenComposite.

 

But with your system you will be quite OK with the Reverb. In any case the Motion Reprojection works very well in Reverb.

Hey, that CPU has something strange. I don´t know why but it was not performing as expected in all the tests we did in the past with the old VR benchmarks (Balapan, Samuel, Chili).

I couldn´t find the reason.

CPUs like 8086K, 9700K, 9900K or the new Ryzen 3xxxX line are quite OK for VR if you put a god GPU and not all settings to max.

You will be quite happy if you upgrade your CPU.
