Chasing frames

[Paul_RSXK]

All too easy to disappear down the frame chasing rabbit hole in VR. I now have over 200 hours in the game, mainly VR over the last year or so. So what have I learned regarding frame chasing?

 

Basically, forget it. 90 frames per second on a G2 headset does not always equate to a smooth playing experience. If you have a rig that can generate an unflinching 90FPS at 100% pixel density on ultra settings great. For the rest of us there had to be a compromise on graphical quality versus frame rate and I don’t just mean the number of frames but more importantly how fluid the flying experience looks and feels.

turn off the frame counter, how does the flight feel? Smooth, fluid, good visuals? You don’t need 90FPS to achieve that outcome.

 

I run an i7 10900k processor and an RTX 3080 card. Win 10 platform and the latest nvidia driver.

I have open XR running, with the toolkit and open composite.

big hitters:

clouds to minimum. There is zero difference in quality in VR.

monitor off. You don’t need it.

horizon set to 70k

in game sharpening off

MSAA  x2

grass on low

Everything else is as per ultra default

 

WMR window

MR set to disable

Scale set to 1

That's it. Once set forget about it.

 

Open XR 

once you set your in game graphics, control everything from the toolkit

80-100% on the graphics using FSR upscaling

resolution override on

MR on at 45 frames per second

sharpness set to suit, you can crank it up to 100% (less is better in my experience, especially with the graphics at 90-100%. The higher the percentage the graphics is set at the less ghosting I'm seeing (virtually none TBH at 90-100%) I've dropped back my sharpening setting to 10%, in minimizes any shimmer on the shadows and landscape.

 

 

Using those settings I get a rock steady 44-45 FPS, and a very fluid  flight experience with great looking graphics. You can tweak the graphics setting between 80% and 100% it makes little of no difference the the frame rate, but settle on the most fluid experience for your rig (90% seems to work fine as an upper limit for me. (100% brings a bit of lag close to the ground even though the frame rate doesn't drop below 43 it just isn't anywhere near as fluid as 80-90%}.

16 plane furball over Normandy, 45 FPS, butter smooth and because it is MR you are seeing a 90FPS equivalent in the headset flight experience. Perfect ???

I agree about fps. Rocking steady 60 fps with 30% GPU overhead on quest 2 (locked fps via sidequest command), super smooth and no frame drops. I remember reading that some people see flickering on lower framerates.

 

Also, i just learned that i had "unseen" pixels/too large fov.  My field of view was limited physically due to prescription lenses on quest 2, and reducing those unseen pixels (by reducing fov via oculus tray tool) lowered rendering cost 30-40% and i could use that horsepower to crank up the graphics.

Hello - I've done a lot of reading/checking etc and have my Quest 2 set up looking great (in my opinion).  Can you tell me what your Display Resolution (per Eye) is set at in the XRT System tab please, and also please tell me what "MR" means.
