question about Varjo Aero and Pimax Crystal

[Phantom711]

Hi...

So I am wondering, how much supersampling do people use with those HMDs? Isn´t it pretty hard for even e 4090 to push all those pixels (even with DFR)?

I went for the QPro intentionally because I thought it would be insane to go for such hi res HMD...but then again I also supersample by about x1,7 also which ends up rendering more than 3000x3000 per eye. 

So my question actually is: Does the need to supersample actually decrease with a higher native resolution so that at the end it doesn´t even impact performance that much?

 

My specs: 13700K/4090

Hi,

 

I don't need any AA with my Crystal to get a 4K Monitor like picture. I have to use Eye Tracking for this.

You can use DLSS or only DLAA if a little shimmer at the edge of your vision is bad for you. With DLSS you will get much more blur as with DLAA only, but you will get with both ghosting at !!every!! fast moving object.

You don't have to add any kind of supersampling with one of those VR-HS, and the picture will look a way better as with a quest pro.

Inversely, I see no noticable ghosting with DLSS in the aero, DLAA alone is slightly crisper but then it's 20fps slower; on my hardware it's a no brainer, especially as I see no negatives to it.

No AA is not an option for me though, even at 39ppd in the aero DCS is still a shimmerfest, MSAAx2 almost gets rid of it but DLAA completely eliminates it

Thanks for your answers so far.

My question was not about DLSS/DLAA though but about by how much you increase render resolution.

As far as I understood, @Nedum you don‘t increase it at all.

[edmuss]

I don't supersample at all, set the resolution in varjo base. Generally it's one of the following configurations: -

35ppd and downsample the peripheral to 0.85

Or

39ppd and downsample the peripheral to 0.75

Some people supersample the focus area as well but it's rather have the frames as I'm GPU limited.

Edit: for reference, at 39ppd foveated, the aero pixel count is about 14mp. The G2 @100% render resolution is 19.5mp.

@edmuss

Thanks…those kind of the numbers I was looking for. 
What turns me off from the Varjo is the fact, that they don‘t offer refresh rates lower than 90Hz.

[edmuss]

It's annoying that they aren't willing to offer a lower refresh rate, however I've found the varjo runtime to be pretty smooth even below refresh rate; certainly much better than WMR.

With a 4090 and decent CPU you should be hitting 90fps in most modules. Some scenarios it's just not possible of course.

With my system I'm at about 75-85fps in the hind on Caucasus and about 5fps less on Syria (apart from Damascus which is about 65-70fps). A10C and AV8B are pegged to 90fps nearly all the time.
