IL-2 tested in Pimax 8K

[chiliwili69]

 

They are running IL-2 in a laptop with 1080p screen. Good to know they included IL-2 in the list of games to test!!

Very promising news! Expect to receive mine in before Christmas!

This guy is me, I wrote up immpersions at Pimax forum:

(BTW test was on desktop PC with gtx 1080ti and 1080p monitor)

 

"Guys finally my honest impressions after returning to home ..

First of all I was very positivly suprised about how well organized was Berlin meetup, which gave me plenty of time to test my favorite games and switch between devices as many as I want. I was there since 5 till 8.20 PM and I would stay even longer as an meeting atmosphere was fantastic ( thanks to whole Pimax team , Marcin , Sebastian and Thomas) but unfortunatelly I have to leave becouse my kid get bored. I'm happy that they allow me enter with my wife ( not a backer) and 2.5 old doughter to the meetup which I really appreciate !

My first test was the leap montion expirence on 8k and laptops powered by gtx 1070 prepered by Robin Weng. It was fantastic and IMHO the best expirence of the day
Then I meet Martin and he introduced me 5k plus with Skyrim, ED and later 8k with sims like Asseto Corsa , ED, IL2

What I like:

• in both devices 8k and 5k - they already implemented IPD indicator with values shown inside HMD. Long awaited but needed feature !
  • SDE / PPI in both headsets great , hard to notice differences, hard to notice SDE ( 5k PPI is enough with RGB panels)
  • FOV ! and 3~4 profiles to set
  • comfort was ok , my glasses fit inside , no problems with nose gaps , YES I can see light coming thru this gap but I like it that way becouse I can glance on keyboard when playing my favoirte sims
  • both headset very light ( compared mostly to my preordered vive unit, and PSVR)
  • the lenses ( apart of distortion part) was great , super crisp, didnt notice god rays, around 120~140 degree sweetspot !

Issues to improve:

• distrotions similar to vive gear vr mod but larger between 5~10 % of each side , noticable for example in skyrim vr when looking at trees or high bulding geometry, should not be a huge problems in sim games like ED , IL2 , DCS, AC , PC 1,2

• I understand that both headsets are using LCD screens but please Pimax engineer provide a software calibration settings for user. I want to adjust colours temperature , brightness and saturation , I really dont like black level ( more grey than black) in ED.
  I tryed lower gamma inside game but it seems that something ( software or hardware) locking it still at very exagerated level and for me was hard to be immersed that I am in space .

• Asseto Corsa tryed only on 8k unit and visuals was great only at front plane , I observed lots of distance blur. It was like on my Vive without supersampling. Together with Sweviver we tryed using different supersamplings levels ( Steam VR app shown very high values like 4200x2500 pixels but that input resolutions wasn't on the screen. Game wans't reacted at all for supersample changes.

• The same problems was with IL2 but Marcin said he was able bump up resolution when changed monitor resolutions at home ( He have 4k monitor) but during meetup we had only 1080p monitors. In vive monior resolutions never was related with HMD resolutions ! It's a big issue for me.

I hope that thouse issues will be fixed by Pimax team or game developers but should be adressed before relase.

Conlusion:
I am thinking about changing my pladge for 5k plus and dreaming about 5k plus with RGB OLED screens"

You were able to read the labels in cockpit at 1080p res, this is the res I am planing to use for now with my 1070q laptop.  Maybe try 1440 when Pimax gets brainwarp running.  Hopefully by that time they also are able to implement HMD res independent of monitor res.

 

The FOV seems to be ideal for Il2 BoX.

Hey! Good to know you were there (How did you convince your family to be there??  )

 

Nice review. Thanks for sharing. Specially the large sweet spot!. (not like the horrible VivePro!)

Let´s see if they find why the resolution is dependent of the monitor resolution...that´s quite strange.

 

They should demo IL-2 (or ED) in this platform in their next meet up:

https://forum.il2sturmovik.com/topic/30766-new-moving-platform-with-pimax-8k-24k/

 

What about the inertia of the device when you move 10-5 degrees right and left quickly? is fixed enough to the face?

Why you should change your pledge for the 5K plus? is not 8K always better for SDE?

Berlin Zoo and Aquanarium was attraction for them next to our hotel.

We should not concentrate on SDE only while choosing headsets. Both are great ! Almost 0 SDE in during my tests in Berlin in both HMDs. For me more important is distance resolutions, far objects , ablility to play without AA, crisp, detailed picture without distance blur.

5k in my opion is better for sim games, you can bump up resolutions, supersampling and get more detailed distance view.

I watched almost all the vids and written reviews by backers on the PIMAX site, including yours chiliwili69 and TWHYata_PL which I thank you for.

 

When I watched the IL-2 vid I was surprised they had the resolution set to 1080 and wrote it off as them not knowing the game.  Now that I know it was a monitor related issue this brings up some concerns. It would mean the 8K was upscaling to 2160 or 100% vs its intent from 1440 or 50%.  I would think this would have a direct impact on the quality of the image.  

 

If the 5K+ was also working on a 1080 monitor vs 1440 native there would be loss of detail.  I experience this loss on my 32" 1440p monitor if I drop it down to 1080p.

 

I am not sure that a HMD upscaled 100% vertically from 1080 to 2160 is directly comparable to one stretching the screen vertically ~33% from 1080 to 1440.  Seems to be apples to oranges IMO.

 

This brings up another issue as well.  Since they were running at 1080 we don't have a good indicator of what the true 1440 input fps is for either unit.  I would also think the SDE would be different with 1440 input.

 

This is disappointing as I thought we were getting good apples to apples looks at the units by the backers.  Until we see both units functioning from a 1440 input and compared side by side will we know the true difference of them.

I'm thinking that this not a case with 5k unit. 5k plus is using different rendering techniques without upscaling. I have seen munch more crisp detailed distance objects in 5k plus , that was in elite dangerous and skyrim VR.  5K unit is easest to supersample input resolutions - that statement  ofcourse is only my opinion without deep testing of both units.

I'm sorry if this is going OT, I can delete or move it to another thread if wanted. 

 

My dilemma, like so many others, is which unit to go with, the 8K or the 5K+.  I'll be the first to admit I lack knowledge of hooking up multiple displays to a graphics card.  My whole concern above may be flawed due to this lack of knowledge.  My assumption is that in nVidia CP each display can be designated with its own resolution and Hz.  If a game however, such as IL-2, is set to a res of 1080 won't all displays attached receive a 1080 input?  Conversely, if the game is set to 1440 for the Pimax, what would happen on a 1080 monitor attached, would this be controlled (down sized to 1080) through the CP?

 

Thanks

Correct

No, only the monitor where IL-2 is running, and only if the game is set to run in fullscreen.

You can choose the size of the mirror shown on the screen. Normally this has no impact on the size of the render buffer for the headset. That it does in this case is either a case of confused users, or bug in the PiMax drivers. Hard to say, but hopefully we will know soon. SweViver has the game and likes it, and he has received the (hopefully) final build of the headset. I don't think he lurks on this forum, but it should be easy to contact him on the PiMax forum. But for now he is under NDA, so no info before it's lifted on the 16th of September.
