Cropping FOV for performance gain

[Zligor]

Hello pilots,

I am starting this topic because i recently changed my vr headset to psvr2, and now having performance issues.

Before i was using quest2 on link cable but with magicall tool called OTT(Oculus Tray Tool). In OTT i was using option called fov reduction, set to 0.8. It actually crop the image so performance gain is huge. Our eyes anyway don't see that outside region of 20% (differ from person to person 10-20%, someone is ok with 0.9, someone with 0.78...,ipd and head shape are reason).

Question no 1: Is there a way to make and implement such tool for psvr2 and other steam displayport headsets?

Question no 2: Am i wrong or ott was directly forcing dcs world to crop image before rendering? If yes than it means that ED left opened that option so it is easy for developers to help us here

I think there is a version of OXR toolkit that does this?

Couple of options come to mind:

1. OpenXR Toolkit

2. Use Quad Views (install Quad-Views-Foveated and also Tally Mouse's Quad Views Companion app to configure it, and then enable Quad Views in DCS). Will reduce load on the GPU, but increase on the CPU (as it is creating 4 views instead of 2) although you have an AMD 5800x3D so this shouldn't be an issue, by creating higher resolution on the inner focused portion, and a lowered resolution on the outer region. The PSVR2 now has eye-tracking which makes Quad Views a definite option as if you use this then you'll only see the higher res image, the lower res will be out of view so you can make the lower res portion much larger. You could see some significant improvement with this.

If you decide to try Quad Views then don't use OpenXR Toolkit at the same time.

I allready use quad view companion (foveated area 130%, ouside area 10%). QVF and eye tracking is reason why i bought PSVR2.

I lowered shadows to flat, was on high. Turned off SSAO, was on...and lot more. And it stutter. Only solution is PD to 0.8, but it's terrible. Steam VR render is on 100%.

Could be that 4070ti super is just not enough. Or 5800x3d not enough for 90fps. Or i am missing something big. I need that fov reduction/crop.
