Compulsory Deferred shading kills FPS in VR

[Charlie-1]

This is really disappointing having upgraded on the premise of improved memory and offline play to find deferred shading now compulsory and HDR option gone. The thing is as nice as DS looks, it kills FPS in VR, for me anyway.

 

A Nevada game with no clouds I normally achieve 50-90 FPS, but with Deferred Shading on its stuck below 40 and averaging more like 35.

 

Is this issue known to ED? If so, why ruin it for us VR players?

Agreed. Turn off MSAA will make a big difference frame rate wise, but visually it will be very shimmery and jaggy.

DCS looks great nowadays, the downside is that even a 1080Ti has to struggle to survive.

 

With all HIGH you basically end up 45-100fps, not 100-180fps

I'm no expert but from what I'm reading the advantage of Deferred Shading is for efficient rendering of scenes with hundreds or thousands of light sources. Other than that its less effective than forward shading due to its dual pass process. Might explain the performance hit?
