Pimax crystal light

[sam22]

I have gotten OpenXR and up to 90 FPS. Inside the cockpit looks amazing! But looking down on the ground it looks a little off. Does anyone have a good fix? 

 

[Dash,Polder]

In what way does the ground look off?  In graphics try setting the landscape filter off, than manually edit the startup.cfg file in the data folder for these values,

    land_anisotropy = 16
    land_detail = 7
    land_tex_lods = 3

See what that does for you in the up close department, it really won't do much for anything at distance, nothing you can do about that.

 

And turn off the game sharpen, the PimaxPlay one is far better this time around, use that one.

Thank you! I will try this out for sure!

Last thing I'm at about 85 FPS last thing I can't get right is the other Airplanes kinda are blurry until 4 X zoom on them from closer than I'd like to be. Any fix for this by chance?

Trick I personally use for PxC Light is a vertical offset of 1.8 each eye, what it does is even the numbers of pixels, instead of 3800x4500 it's now 3800x3800.  You've reduced the over all pixels generated with no visual degradation, I think the game looks even cleaner with the pixels balanced.  Physically the screens are square anyway and have the same physical number of physical pixels on them both vertical and horizontal.  It allows you to boost slightly higher res on the slider for the same number of pixels generated.  More res will always clean up your views nicely. 

Other than that SSAO off, HDR on, and (bloom_enable = 0) manually has to be set in your startup.cfg, that and working with sharpening is the airplane spotting cleaner.

If your system is a beast set texture filtering quality to (High Quality) and power management to (Prefer Maximum) in NVIDIA control.  I get the impression top end GPU's run IL-2 far better at maximum graphic settings than they can with degraded settings, they seem to choke on the lower settings, so crank textures up.

Oh you run HDR on? Most ppl have said not to. Does it help with the ID’ing of ENY? My spotting has improved just telling who they are is more of a struggle

It should give the planes better reflective properties, richer shadows and easier to see their motions and movements at the mid ranges.  That's what you want to look for when testing.

Do you touch resolution override in the toolkit at all? Or leave it off? 

[Dash,Polder]

No reason too, you can do that in Pimax Play, but the OpenXR Toolkit is nice to check at what res your screens are actually running.  Mine runs best at close to 3800x3800, anything above that and it starts to stutter in a heavy loaded online match.  On a 7800X3D and 4090, so pretty beefy for IL-2, but even than trying to push anymore than 15 million pixels just don't work.  I'm good with 90 FPS up to that number and a bit beyond if only doing single Quick match type simple flying.  It's good to know how many pixels your system is good for, that's the limit, than you can tune all the other graphical stuff with that in mind.

Thanks! I'd love to see just all your settings LOL. I was rocking HDR today and sharpening and I was getting good frames but I'm new to VR and coming from an OLED monitor its a big difference making that jump

Как и где это сделать? Спасибо.

In pimax play there's a universal setting for offsets under 'Advanced' tab, called Horizontal IPD Offset for left and right lens, slide both to right + 1.8.

I am a bit confused.  Is it the vertical offset in the first quote, or the horizontal IPD offset in the second quote, or both?  Thank you.

[Dash,Polder]

Sorry, vertical.  Think you'd notice the horizontal effect somewhat jolting.

Same IPD offset for Crystal? I have 35PPD lenses.

Would this technique be of any use to me? I have Pimax Crystal (35ppd) and as I understand it has res of 2880x2880.

Thanks,

@Dash,Polder  I just finally got around to trying out the 1.8 offset, and it really seems to make a nice difference.  Thank you for the tip.  Do you have any suggestions for getting rid of ground shimmer?  Also, I cannot fly near Leningrad or Odessa without losing gobs of framerate.  Please send along your experience and any ideas.

I have an I-9 14900K, RTX 4080 Super.

[Dash,Polder]

Don't have the Odessa pack, not really interested in it, but sharpening is the key to shimmer in any high res HMD in this game.  There are three separate sharpening approaches and they all stack on top of each other, and that conflict can cause shimmer problems.  Make sure to only use the Pimax sharpening feature.  Turn off the NIS in Nvdia control panel while the game is open, only time it's fully accessable in the IL-2 profile.  By default it has a level already set on, you want to start with it off, both sliders and they only appear while the game is active.  Also ensure the games own sharpening setting is off.  Than use the Pimax play sharpen within it's IL-2 profile.

If your going to fine tune use the NIS in small amounts with PimaxPlay sharpen and test the results.  It also affects spotting, you can get really good results with small amounts of Image Sharpening (NIS) Sharpen and Ignore Film Grain sliders in your control panel profile.  They will change live as your in your HMD in game, so you can tune them really well in a quick mission and see the results as you tinker.  The multiple dogfight is excellent to play around with since you can set your contacts to start out at 10,000 meters away, do it in a clear sky and see the best combination you can come up with.  Spotting and shimmer seem to me to be strongly related, low shimmer and better spotting.  Wouldn't worry about extreme horizons so much, they're never looking good no matter what you do in this game, wait for Korea.

@Dash,Polder  Thank you very much for the info.  I will give them a try very soon.
