VR Rendering Questions

[j9murphy]

This will probably be a few posts as try and dig deeper into understanding how to "tune" VR settings, but I want to try and understand what's going on so hopefully a few of you are guru's in this area...  Question 1....

 

As I understand it, simplified of course...

 

1) PD in DCS VR settings together with the DCS graphics options determines the resolution and quality with which DCS renders a frame. The amount of CPU time and GPU time to do this is tied to the complexity of the scene and the specific graphical options selected.

2) the frame is then passed off to the GPU to scale the frame (in this case through steam) based on the value specified in supersampling (could scale up or down)

3) finally the frame is scaled again by the GPU based on the actual resolution of your VR headset and displayed

 

is this correct?  is there a way to see what the contribution of CPU/GPU at each step is to the overall frame time?

No, the frame is only processed by the gpu once, is my understanding so resolution for the game, is adjusted by steamvr settings and is then processed by the gpu.

are you saying that essentially 2 and 3 above are done in one pass by the gpu?

Yes
