having a mod that uses satin, reduces performance heavily
for example Paradise Lost: https://github.com/devs-immortal/Paradise-Lost

this has likely to do with out render target changes.

happens in VR and NONVR, since we apply the changes in both versions

specifically this call is slow

Is there a fix for it? Will it ever get fixed?

current workaround, is disabling the eyestencil in the rendering settings

fixed with 1.2.0, which autoimatically disalbes the use of the stencil buffer when satin is detected
