DCS and Pimax


Recommended Posts

Did you try Pitool quality at 1.75 and steamVR SS at 20% ?

This is my config, plus PD in DCS at 1.3. I found that increasing Pitool quality improve globally image more than applying SS, in steamVR or in DCS, to have the same output resolution. Maybe it's placebo, but my idea is, as Piserver/Pisevice are rendering image, that they may have rendering option activated when you increase Pitool quality...You can also try the opposite : reduce Pitool quality at maximum, increase SS in steamVR to keep the same resolution and see resulting image...if there is no rendering option in Piserver other than output resolution, image should be the same...I did not find the time to test.

And also, activating SS in Pitool is not placebo. fps at ~45 without SS provide a non smooth experience when moving head (especially for left to right strafing move when looking Dashboard). Same situation at 32 fps with SS for 64 fps target is smooth, without too much articfact.

 

Did not tried your settings yet, but am always very interested in your configurations and impressions.

But I don´t share your opinion on the point, that increasing the render resolution by Pitool activates a hidden process for the benefit of anti aliasing. I don´t think that there´s a secret function in Pitool´s algorythms, that is more efficient due to supersampling than in SteamVr or DCS PD setting.

 

Another point I disagree is the circumstance of downsampling by SteamVR to 20% and then upsampling by Pitool to 1.75 render quality. In my opinion downsampling should be avoided in the render process, as it effects in a loss of image information/quality.

Currently I´m tryng to keep SteamVR at minimum to the native render resolution of 2560 x 1440 per eye respectively 2560 x 1616 as adjusted by SteamVR.

 

Following the renderpipeline is still a bit mystery, but so far I think DCS´ PD setting results in a more efficient scaling/supersampling as the image is created by DCS´s graphics engine; each step after this image creation only deals with upsampling/downsampling with the predefinition and does not add more image information/quality than DCS graphics engine could do. My assumption is, that Pitool´s rendere quality setting only supersamples the predefined image.

 

Agree that Pitools smart smoothing is efficient. So far I don´t see so much of a difference regarding the smoothness while moving the head, but I could see a difference in a tearing/ washing out effect in the cockpit without Pitools smart smoothing. Pitools smart smoothing is surely no placebo, like our individual impressions could be - I will keep it activated.

 

In anyway we could reach comparable image quality by different approaches - interesting on this, which approach is more frametime/FPS efficient, but differences might be marginal and only perceivable in minimal difference in measured values, but not in game.

 

Maybe there will be coming up more adjustment screws to discuss, when Pitool becomes open source. In anyway we could reach perfect image quality with the 5k+ with better performing Hard- and software behind. Especially software and compatibilty is constantly improved, whether steamVR ( openVR ) compositor or PiService compositor.

 

Now, let´s have some fun with the witchhunters´s comments in the internet trying to destroy Pimax´innovative approach for VR at affordable prices with recent announcements. :-)))

For those interested, I have posted all my settings on this thread I started.  Getting anywhere between 50 and 60FPS on just about every map.  Some times it dips to 45, but usually sticking around 50

Dear all,   While it's too early to know exactly what will come from it, we are in touch with Pimax regarding their 8K system and how we can best cooperate for an amazing DCS VR experience.   Thanks

For the ground that can be pretty normal since DCS always has a FPS hit on the ground/low altitude. Start a free flight in the air to see what it is. Even then I doubt you'll be able to hold 80 fps

Someone did a good summary of the "Pimax day" event.

 

 

 

  • The Pimax "Vision" 8K X is slated for release Dec 18th. Dual native 4K inputs through one DisplayPort 1.4 cable. Can use internal upscaler, if desired. New RGB stripe panels instead of pentile as in the current 8K. Better panel utilization for higher pixels per degree. Cost is $1300. Includes the new "Modular Audio Strap" and "Vision Comfort Kit."
  • New Pimax "Vision" 8K+ is slated for release Oct 30th. Same improved panels and manufacturing process as is what's going into the 8K X, just no option for native dual 4K input. Cost is $1000. Also includes new Modular Audio Strap and Vision kit.
  • New series of Pimax RE (Rugged Edition) headsets. Not intended for consumers, as you need to contact Pimax directly for a quote, but they're essentially made of reinforced metal, with redesigned PCBs, and coated in water-resistant materials. Intended for VR arcades.
  • There's an upgrade plan for people with headsets already, and Kickstarter backers get pretty steep discounts on the new headsets, if they desire. Not sure details.
  • Valve Lighthouse 2.0 basestations are shipping in next couple of weeks to backers.
  • Pimax Sword and Sword Sense controllers are coming along well, but like March for the Sword and June+ for Sword Sense.
  • Due to the long wait time for controllers, they're offering Kickstarter backers the ability to switch to the Valve Index controllers at a nominal fee (at cost, essentially).
  • Modular Audio Strap is shipping in December to backers. Modular in the sense that the headphone design is completely replaceable. By default, it uses an off-ear design with speakers built into these 'pucks' on the side. They claim the audio is great, but will offer high-end over-the-ear headphones as an additional option for those who want. Over-the-ear drivers are made by a "well known" audio company.
  • Vision Comfort Kit is an additional part that appears to be separate from the Modular Audio Strap? It's basically got a much bigger foam pad for your forehead, as far as I can tell, with a nose guard to eliminate light leakage. Ships Nov 1st, cost is $50.
  • Handtracking module is shipping Dec 18th to backers. Optimized for Pimax, wide FOV, and high refresh rate. Co-designed with UltraHaptics, who now own LeapMotion.
  • Eye Tracking module being developed with 7Invensun. Customized for Pimax's wide FOV and "ready for Dynamic Foveated Rendering." Ships Dec 15th to backers. BUT, it will not come free to backers like previously promised as a part of the stretch goals. $200 for backers, $300 for non-backers. Costs to custom design for wide FOV of Pimax headsets was apparently too great to offer for free. Take that as you will.
  • Cooling fans as a part of the stretch goals will begin shipping in the 3rd week of October to backers. Backers must fill a request form for them on the Pimax website.
  • Prescription lenses frames are the same as cooling fans. Shipping in a few weeks if you fill out a form requesting them. Can also 3D print your own with the design files they're uploading.
  • 10 meter cable for Pimax headsets coming in November for backers. $100 cost.
  • Three pieces of free content for Kickstarter backers are "The Dream Collector," "The First Class VR," and an unannounced sword fighting game optimized for their Sword and Sword Sense controllers. To be revealed in November. Steam codes for the other two will be send this month to backers.
  • Pimax 5K+ is getting a firmware update to enable 120Hz mode. Apparently the 5K+ panels are native 120Hz, but it requires you to lower the FOV to the low setting.
  • Something about Brainwarp 1.5? It's in the table of contents, but don't remember them talking about it.
  • PiTool is going open source as of today. Will be open sourced in three phases, phase 2 is coming 3rd week of October. Phase 3 is in November.
  • Wireless module was not really discussed, but is still in development of course. It's been challenging, and will not be discussed further until next year.

 

 

I watched the video... looks very impressive, fingers crossed!

It looks even more impressive in through the lens zoom photos, comparing 8kx with 5k+. Improvement is on pair with boost we had going from first Oculus Rift to 5k+. Check this out!

Hello all.

I have a Pimax without base statons. And I did not used my Pimax 5K since April. Two Days ago I run my PC, connected Pimax all works fine. Yesterday I installed Win 10 (insead of 7), new version of Pitool and when I connected Pimax, firmware was updated. But now I see the message that device is not tracked. Pitool ask me to configure my room, but does not see a base station (as it is absent). I'm not sure but as I remember in old version of pitool I was able to chose using Pimax without base station. But now I can not find this setting.

Does smth was changed and now it is not possible to use Pimax without base stations?

Latest video reminded me again, how limiting small FOV really is. Pimax is not perfect, to start DCS on my 5k+ is around 2 minutes procedure, but it is still worth it for me. Of course, I have a monster PC, which although struggling, but still managing to deliver somehow acceptable performance on close to maxed out graphic settings. 8KX is a day-one buy for me.

Although I'm really excited about The new Pimax headsets.....I'll need to see exactly what kind of discounts they're offering Backers of the first series....I'm pretty happy with my 5k+:thumbup: It seems The World of VR tech is progressing faster than my wallet can recover:cry: At some point....I'm going to have to skip a few levels of progress.:doh:

I am in the same situation as you. My next buy wil be the next gen Nvidia, to make better use of my 5k+. After that i will look for what then is a good VR headset.

The 5k+ still has good life in it, it is the graphics card that is the bottleneck.

hi there

i have a pimax5k and await one lighthouse basestation (1) next days

can you tell me how to bring them to work and where the best position for the basestation is

im confused about the basestationtechnice - because there are not connected to the pc

 

 

 

thx 4 help

 

so the HMD has to find and identify them ?

Seated position is very easy. Just put one in the top right corner of your room and the second one at a lower position in the left corner behind you.But at all time at least one light house needs to have clear sight on you. You should not be able to get into a position where both lighthouses lose sight on you.

EDIT: DId you just say you have only 1 lighthouse? Then you should just put it at position where it can always see you. But I am not sure as I own two lighthouses for my Pimax

so the lighthouse must see me or the hmd all the time ?

because i wouldt like it to place the basestation on the upper right (45° from my pos.)

 

so when i check my 7-8 clock the basestation will maybe dont see the hmd - or just a part from it

 

how the communication works between hmd , basestation and pc ?

It is a laser beam ( cone) which is shot in a wide angle out of the lighthouse. Very wide angle. I think, if the HMD loses sight it is not too bad for a quick amount of time as it compensates with the gyros, and starts tracking again, if the HMD sees the lighthouse again. For the controlers ( in case you have them too) I think if they arent seen, they lose tracking instantly

if i launch dcs over pitool dcs is bugged and some moduls didnt work (fc3 for example)

 

your frames are limeted via ffr i think

 

i wouldt recomment to use parallel projetions only

all the other options didnt work very well in dcs i mean

fov has a big impact not only in fov also in a much higher resolution - thats why i use large fov

you can even see missles very good

Does anyone have better performance with it? My P5k+ is RMA at the moment so I can't test it.

Yeah, it´s fine, SteamVR shows a more appropiate resolution in normal FOV, but the 120Hz mode doesn´t work for me at the moment - doesn´t want to reduce the FOV anyway.
