Gents ...

 

I'm only getting about 20-30 fps with my Pimax 5K+ on my machine. Settings as shown above for Pitool and DCS ( operating at 90Hz on Brainwarp )

 

Computer Specs are as follows:

 

i9 7980XE overclocked to 4.7GHz

64GB RAM

1080Ti

Windows 10

 

Also, cockpit clarity is ok (love the fov) but when I move my head in the cockpit, it sure is blurry until i finally stop moving my head.

 

Any words of wisdom on tweaking the above?

 

Thanks

Did i read somewhere that DCS does not use parallel projection ? FOV set to 150 ?

I turned off Parallel Projection with no noticeable effect ...

I don't have a Pimax (wish I did) but off the cuff I'd say the biggest drags on VR performance are anti-aliasing (supersampling, MSAA), shadows, and vis range and trees. I think the nugget of the thing is to see where your PD and steam supersampling are compared with other Pimax users. You could try setting vis range to medium, trees around 50%, grass/clutter off for now and see where you're at. But I got a nickel says its SS

Watched a 2-1/2 hour in-depth video by Sweviver on pimax 5k and 8k last night . With a similar system , he was not a happy camper in DCS . Had all his DCS settings low , steam supersampling to 30% to get frames in the 35ish range . Also watched a couple of (sounded like) Russians flying a Tomcat get low to mid 30s AT ALTITUDE depending on whether another aircraft was in the frame . I'm afraid you're gonna hafta majorly dial down your DCS settings expectations-at least until the VR terrain engine fix coming "soon" . This will give you 50% more performance .

You were right. SteamVR SS was set at 200%. Once I dialed it back to 90%, I got into the 20ish FPS range. :cry:

I'm afraid you're absolutely right.

 

It's a shame people spend a ton of money on a rig that, according to the presale hype of the Pimax, is supposed to offer a good VR experience. What they don't tell you is that software companies need to do their part to keep pace ( as is ED ).

Sweviver mentioned another more VR-friendly flightsim that ran very well indeed with the 5k-on a 1070 !

I read something that pimax5k looks great on paper, but it takes a top end rig with a 2080rtx titan just to run It with any satisfactory performance at its large res and large fov. Just upping screen res and fov outpaces current tech that doensnt exist yet. VR needs foveated rendering and spot on eye tracking to make high res lenses and large fovs practical.

And people are excited about the Reverb , etc , which will run even worse !
