"Smoothed" lateral head motions with parallel rendering?
-
I noticed that when parallel rendering was set to “1”, the VR image looks as if it has been smoothed, I.e., there is a little bit of deceleration when you move your head up and down and suddenly stop. It leads to a somewhat “floaty” feeling in the cockpit.
While this increases FPS, it also feels quite uncomfortable. Is anyone else experiencing this, or is it just me?
P. S, To my understanding from what has been shared by the devs before, it’s due to serializing the sim and render threads to avoid a race condition; I wonder if this is a BMS engine limitation, or if this will eventually be “solved” and optimised.

@gankailer I also noticed this and it was one of the main reasons I turned parallel rendering off.

I have the parallel rendering set to “1” and nothing feels “floaty” for me. I just enjoy the extra FPS. -
Does the parallel-render-thread cfg option have the effect of adding 1 frame of input-latency? (I suspect so, but I haven’t tried to measure.)
If so, you could just be feeling the additional input-lag. For VR, asynchronous reprojection is supposed to help with that. Not sure if that’s a separate setting or something specific to headsets…

@gankailer it happens to me if i move the head very fast.
I learned to do smooth movements as I prefer higher fps -
@gankailer hi, which VR set do you use? For the record, I have the same if I use virtual desktop instead of oculus link.

I have turned off parallel rendering as well due to this, as the movements are more crisp, but that definitely comes at the cost of good FPS. With a 5800X3D this isn’t too bad, of course, but in situations whereby many draw calls and calculations are made (such as being on the ground and loading the TGP, or looking at a burning column with lots of explosions), the FPS can really take a hit.

I use a Meta Quest Pro at the moment, and connect to BMS via Airlink. I will try it on VD and see if there is any discernable difference when parallel render is turned to ‘1’
